This compound inequality reads, “, 1.” The shaded part of the graph includes values that are greater than or equal to, Correct. You read −1 ≤ x < 5 as “x is greater than or equal to −1 and less than 5.” You can rewrite an and statement this way only if the answer is between two numbers. Sometimes, an and compound inequality is shown symbolically, like a < x < b, and does not even need the word and. In words, x must be less than 6 and at the same time, it must be greater than 2, much like the Venn diagram above, where Cecilia is at once breaking your heart and shaking your confidence daily. In other words, both statements must be true at the same time. When the arrow points away from each other in the number line, then the inequalities are joined by 'and', if arrow points on same direction, inequalities are joined by 'or'. A compound inequality is a statement of two inequality statements linked together either by the word or or by the word and. Check the solutions in the original equation to be sure they work. A) h < 3 or h > −3 Incorrect. First, draw a graph. The solution to the compound inequality [latex]x\gt3[/latex] or [latex]x\le4[/latex] is the set of all real numbers, and can be described in interval notation as [latex]\left(-\infty, \infty\right)[/latex]. If we are describing solutions to inequalities, what effect does the or have? The distance between these two values on the number line is colored in blue because all of these values satisfy the inequality. First, it will help to see some examples of inequalities, intervals, and graphs of compound inequalities. For example, this Venn diagram shows the intersection of people who are breaking your heart and those who are shaking your confidence daily. What do you notice about the graph that combines these two inequalities? Use x for your variable. The next step is to decide whether you are working with an OR inequality or an AND inequality. In the following example, you will see an example of how to solve a one-step inequality in the OR form. Inequality: [latex] \displaystyle x\ge 4[/latex], Interval: [latex]\left[4,\infty\right)[/latex], Solve for x:  [latex] \displaystyle {5}{x}-{2}\le{3}\text{ and }{4}{x}{+7}>{3}[/latex]. Then, solve both inequalities and graph. Test. This tutorial will take you through the process of splitting the compound inequality into two inequalities. Simplifying logarithmic expressions. There are two types of compound inequalities: conjunction and disjunction. Solve for x. Isolate the variable by subtracting 7 from all 3 parts of the inequality, and then dividing each part by 2. Because compound inequalities represent either a union or intersection of the individual inequalities, graphing them on a number line can be a helpful way to see or check a solution. Draw a graph of the compound inequality: [latex]x\lt5[/latex] and [latex]x\ge−1[/latex], and describe the set of x-values that will satisfy it with an interval. Inequality: [latex] \displaystyle x>5\,\,\,\,\text{or}\,\,\,\,x<3[/latex], Interval: [latex]\left(-\infty, 3\right)\cup\left(5,\infty\right)[/latex]. Sometimes, an and compound inequality is shown symbolically, like [latex]a3[/latex]. Notice that in this case, you can rewrite x ≥ −1 and x < 5 as −1 ≤ x < 5 since the solution is between −1 and 5, including −1. The correct answer is h > 9 or h < −3. Interval: [latex]\left[-4,4\right][/latex]. Compound inequalities can be manipulated and solved much the same way any inequality is solved, paying attention to the properties of inequalities and the rules for solving them. [latex]x+2>5[/latex] and [latex]x+4<5[/latex], [latex] \displaystyle \begin{array}{l}x+2>5\,\,\,\,\,\,\,\,\,\text{AND}\,\,\,\,\,\,\,x+4<5\,\,\,\,\\\underline{\,\,\,\,\,-2\,-2}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\underline{\,\,\,\,\,\,-4\,-4}\\x\,\,\,\,\,\,\,\,>\,\,3\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,x\,\,\,\,\,\,\,<\,1\\\\\,\,\,\,\,\,\,\,\,\,\,\,\,x>3\,\,\,\,\text{and}\,\,\,\,x<1\end{array}[/latex]. The next example involves dividing by a negative to isolate a variable. Compound Inequality Calculator. Scientific notations. Notice that this is a bounded inequality. Since this compound inequality is an or statement, it includes all of the numbers in each of the solutions, which in this case is all the numbers on the number line. In cases where there is no overlap between the two inequalities, there is no solution to the compound inequality. The solution to this compound inequality can be shown graphically. > 3 has an open circle on 3 and a blue arrow drawn to the right to contain all the numbers greater than 3. has a closed circle at 4 and a red arrow to the left to contain all the numbers less than 4. Incorrect. The solution could be all the values between two endpoints. The correct answer is −8 ≤ x < −1. Many times, solutions lie between two quantities, rather than continuing endlessly in one direction. When you divide both sides of an inequality by a negative number, reverse the inequality sign to get, 9 but less than 3, and see if they make the inequality true. D) −8 ≥ x < −1 Incorrect. In other words, both statements must be true at the same time. Because compound inequalities represent either a union or intersection of the individual inequalities, graphing them on a … 2 and [latex]−2[/latex] would not be solutions because they are not more than 3 units away from 0. The solution to the compound inequality is. [latex] \displaystyle \begin{array}{r}\,\,\,\,\,\left| x+3 \right|>4\,\,\,\,\,\,\,\,\,\,\,\,\,\,\left| x+3 \right|>4\\\left| -10+3 \right|>4\,\,\,\,\,\,\,\,\,\,\,\,\,\,\left| 5+3 \right|>4\\\,\,\,\,\,\,\,\,\,\,\left| -7 \right|>4\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\left| 8 \right|>4\\\,\,\,\,\,\,\,\,\,\,\,\,\,\,7>4\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,8>4\end{array}[/latex], Inequality: [latex] \displaystyle x<-7\,\,\,\,\,\text{or}\,\,\,\,\,x>1[/latex], Interval: [latex]\left(-\infty, -7\right)\cup\left(1,\infty\right)[/latex], Solve for y. The graph of each individual inequality is shown in color. The points on the line are NOT solutions! You're going to see what I'm talking about in a second. Here are a few examples of compound inequalities: x > -2 and x < 5 -2 < x < 5 x < 3 or x > 6 We can write “no solution,” or DNE. The solution to the compound inequality is x ≥ 4, as this is where the two graphs overlap. Interval: [latex]\left(-\infty, -3\right)\cup\left(3,\infty\right)[/latex]. Square root of polynomials HCF and LCM Remainder theorem. Since the word and joins the two inequalities, the solution is the overlap of the two solutions. C) h > −9 or h < 3 Incorrect. We are saying that solutions are either real numbers less than two or real numbers greater than 6. This can be described using a compound inequality, When two inequalities are joined by the word. Then you'll see how to solve those inequalities, write the answer in set builder notation, and graph the solution on … The solution to the compound inequality x > 3 or x ≤ 4 is the set of all real numbers! [latex] \displaystyle 1-4x\le 21\,\,\,\,\text{and}\,\,\,\,5x+2\ge22[/latex]. In the next section you will see examples of how to solve compound inequalities containing and. Other compound inequalities are joined by the word “or”. In the last example, the final answer included solutions whose intervals overlapped, causing the answer to include all the numbers on the number line. Example 1: Solve and graph: 4≤2x≤8 4≤2x and 2x≤8 (intersection of sets) 4≤2x ≤ 2≤x x≥2 2x≤8 ≤82 x≤4 2≤x and x≤4. Correct. How To Graph Compound Inequalities? The correct answer is h > 9 or h < −3. This compound inequality reads, “x is less than or equal to −8 and greater than −1.” The shaded part of the graph includes values that are greater than or equal to −8 and less than −1. Solve compound inequalities in the form of. You may need to solve one or more of the inequalities before determining the solution to the compound inequality, as in the example below. This compound inequality reads, “x is less than or equal to −8 and greater than −1.” The shaded part of the graph includes values that are greater than or equal to −8 and less than −1. The graph of each individual inequality is shown in color. Can you see why we need to write them as two separate intervals? Incorrect. The first step to solving absolute inequalities is to isolate the absolute value. In this section we will learn how to solve compound inequalities that are joined with the words AND and OR. The graph of a conjunction is typically a line segment on the number line. The solution to an and compound inequality are all the solutions that the two inequalities have in common. When you place both of these inequalities on a graph, we can see that they share no numbers in common. Write both inequality solutions as a compound using or. Compound Inequality Graphs (MATH UNIT 5) STUDY. Solving and Graphing Compound Inequalities in the Form of “or”. The solution could be all the values between two endpoints. After working the problem, they find the solution as a compound inequality, a graph and in interval notation. The following Venn diagram shows two things that share no similar traits or elements but are often considered in the same application, such as online shopping or banking. To solve the inequality 3 – 2, 2. [latex]\left|2x+3\right|+9\leq 7[/latex]. LESSON 3-6 COMPOUND INEQUALITIES Objective: To solve and graph inequalities containing “and” or “or”. So are 1 and [latex]−1[/latex], 0.5 and [latex]−0.5[/latex], and so on—there are an infinite number of values for x that will satisfy this inequality. The correct answer is h > 9 or h < −3. Using interval notation, we can describe each of these inequalities separately: [latex]x\gt6[/latex] is the same as [latex]\left(6, \infty\right)[/latex] and [latex]x<2[/latex] is the same as [latex]\left(\infty, 2\right)[/latex]. Vocabulary compound inequality – two inequalities joined by the word and or the word or solution for and inequalities – (Intersection) any number that makes both inequalities true solution for or inequalities – (Union) any number that makes either inequality true STEPS … If the information on the word problem can be linked with an "and", write the inequality as a single line with two inequality signs. Because compound inequalities represent either a union or intersection of the individual inequalities, graphing them on a … Solve each inequality separately. if the symbol is (≥ or ≤) then you fill in the dot, like the top two examples in the graph … [latex] \displaystyle \begin{array}{l}5z-3>-18\,\,\,\,\,\,\,\,\,\text{OR}\,\,\,\,\,\,\,-2z-1>15\\\underline{\,\,\,\,\,\,+3\,\,\,\,\,\,\,+3}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\underline{\,\,\,\,\,\,\,\,\,+1\,\,\,\,+1}\\\frac{5z}{5}\,\,\,\,\,\,\,\,>\,\frac{-15}{5}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\frac{-2z}{-2}\,\,\,\,\,\,<\,\,\frac{16}{-2}\\\,\,\,\,\,\,\,\,\,\,z>-3\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,z<-8\\\\\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,z>-3\,\,\,\,\text{or}\,\,\,\,z<-8\end{array}[/latex], Inequality: [latex] \displaystyle z>-3\,\,\,\,\text{or}\,\,\,\,z<-8[/latex]. Everything else on the graph is a solution to this compound inequality. In this case, the solution is all the numbers on the number line. In interval notation, this looks like [latex]\left(2,6\right)[/latex]. x must be less than 6 and greater than two—the values for x will fall between two numbers. 4 and [latex]−4[/latex] are both four units away from 0, so they are solutions. Incorrect. The common area is the solution of inequality. jessica_felix_ Terms in this set (16) a statement formed by two or more inequalities. ++ -10-9--8-7 -6 -5 4 3 2 1 1 2 3 4 5 6 7 8 9 10 x The solution to a compound inequality with and is always the overlap between the solution to each inequality. Solve for z. This can be described using a compound inequality, b < 139 and b > 120. Match each inequality to the best verbal statement that represents the … The solution to this compound inequality is all the values of x in which x is either greater than 6 or x is less than 2. Let’s start with a simple inequality. Identify cases with no solution. When you divide both sides of an inequality by a negative number, reverse the inequality sign to get h < −3. The graph has an open circle on 6 and a blue arrow to the right and another open circle at 2 and a red arrow to the left. In fact, the only parts that are not a solution to this compound inequality are the points 2 and 6 and all the points in between these values on the number line. We are looking for values for x that will satisfy both inequalities since they are joined with the word and. The inequality sign is reversed with division by a negative number. The correct answer is h > 9 or h < −3. This compound inequality reads, “x is greater than or equal to −8 and greater than −1.” The values that are shaded are less −1, not greater. The absolute value of a quantity can never be a negative number, so there is no solution to the inequality. Let’s take a closer look at a compound inequality that uses or to combine two inequalities. This is … Write both inequality solutions as a compound using or, using interval notation. Compound inequalities can be manipulated and solved in much the same way any inequality is solved, by paying attention to the properties of inequalities and the rules for solving them. Solve each inequality by isolating the variable. The correct answer is −8 ≤ x < −1. This time, 3 and [latex]−3[/latex] are not included in the solution, so there are open circles on both of these values. 2. Learn. Solve each inequality by isolating the variable. By using this website, you agree to our Cookie Policy. The graph of [latex]x\le4[/latex] has a closed circle at 4 and a red arrow to the left to contain all the numbers less than 4. Remember to apply the properties of inequality when you are solving compound inequalities. The graph of each individual inequality is shown in color. [latex]2y+7\lt13\text{ or }−3y–2\lt10[/latex], [latex] \displaystyle \begin{array}{l}2y+7<13\,\,\,\,\,\,\,\,\,\text{OR}\,\,\,\,\,\,\,-3y-2\le 10\\\underline{\,\,\,\,\,\,\,-7\,\,\,\,-7}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\underline{\,\,\,\,\,\,+2\,\,\,\,\,+2}\\\frac{2y}{2}\,\,\,\,\,\,\,\,<\,\,\,\frac{6}{2}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\frac{-3y}{-3}\,\,\,\,\,\,\,\,\ge \frac{12}{-3}\\\,\,\,\,\,\,\,\,\,\,y<3\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,y\ge -4\\\\\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,y<3\,\,\,\,\text{or}\,\,\,\,y\ge -4\end{array}[/latex]. You have several options: Use the Word tools; Draw the graph by hand, then photograph or scan your graph; or Use the GeoGebra linked on the Task page of the lesson to create the graph; then, insert a screenshot of the graph into this task. The solution to this compound inequality is shown below. If the inequality is greater than a number, we will use OR. In this case, since the inequality symbol is less than (<), the line is dotted. Replace the inequality symbol with an equal sign and graph the resulting line. (The region of the line greater than 3 and less than or equal to 4 is shown in purple because it lies on both of the original graphs.) Isolate the variable by subtracting 3 from all 3 parts of the inequality, and then dividing each part by 2. Check the end point of the first related equation, [latex]−7[/latex] and the end point of the second related equation, 1. Think about the example of the compound inequality: 1. Synthetic division. For example, if you substitute h = 2 into each inequality, you get false statements:  2 + 3 > 9; 3 – 2(2) > 9. Think about the example of the compound inequality: x < 5 and x ≥ −1. Two examples are provided below. This compound inequality reads, “x is less than or equal to −8 and less than −1.” The graph does not include values that are less than or equal to −8. The correct answer is h > 9 or h < −3. The correct answer is −8 ≤ x < −1. Compound Inequalities: Most compound inequalities have solutions containing a range of values. The selected region on the number line lies between, 1.” The values that are shaded are less, 1.” The graph does not include values that are less than or equal to, 8. Whatever operation you perform on the middle portion of the inequality, you must also perform to each of the outside sections as well. Created by. In the following video, you will see examples of how to solve and express the solution to absolute value inequalities involving both AND and OR.  And the solution can be represented as: The two inequalities can be represented graphically as: Rather than splitting a compound inequality in the form of a < x < b into two inequalities x < b and x > a, you can more quickly solve the inequality by applying the properties of inequality to all three segments of the compound inequality. It is the overlap, or intersection, of the solutions for each inequality. There are three possible outcomes for compound inequalities joined by the word and: In the example below, there is no solution to the compound inequality because there is no overlap between the inequalities. (The region of the line greater than 3 and less than or equal to 4 is shown in purple because it … Solve for x. Comparing surds. Spell. Graphically, you can think about it as where the two graphs overlap. The graph would look like the one below. -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 Compound Inequalities Now let's look at another form of a "double inequality" (having two inequality signs). This will help you describe the solutions to compound inequalities properly. Draw the graph of the compound inequality [latex]x\lt{-3}[/latex] and [latex]x\gt{3}[/latex], and describe the set of x-values that will satisfy it with an interval. For example, if you substitute, The solution of a compound inequality that consists of two inequalities joined with the word. To solve inequalities like [latex]a 9 or h > −3 Incorrect. [latex] \displaystyle \mathsf{3}\left| \mathsf{2}\mathrm{y}\mathsf{+6} \right|-\mathsf{9<27}[/latex]. The solution could begin at a point on the number line and extend in one direction. Gravity. The solution is the combination, or union, of the two individual solutions. This compound inequality reads, “x is greater than or equal to −8 and greater than −1.” The values that are shaded are less −1, not greater. PLAY. The solution to an and compound inequality are all the solutions that the two inequalities have in common. It includes values that are greater than or equal to, The solution to a compound inequality with. As with equations, there may be instances in which there is no solution to an inequality. Just remember. Pay particular attention to division or multiplication by a negative. If it is unclear whether the inequality is a union of sets or an intersection of sets, then ##test each region## to see if it satisfies the compound inequality. Compound Inequalities. Logarithmic problems. The next example involves dividing by a negative to isolate a variable. [latex]5z–3\gt−18[/latex] or [latex]−2z–1\gt15[/latex]. It is typically written in interval notation where the range is … The two inequalities would be joined by the word 'and' or 'or'. 3 and [latex]−3[/latex] are also solutions because each of these values is less than 4 units away from 0. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. The correct answer is h > 9 or h < −3. Draw the graph of the compound inequality [latex]x\gt3[/latex] or [latex]x\le4[/latex] and describe the set of x-values that will satisfy it with an interval. When the word that connects both inequalities is "and", the solution is any number that makes both inequalities true. Graphing absolute value equations Combining like terms. This number line shows the solution set of y < 3 or y ≥ 4. In this case, there are no shared x-values, and therefore there is no intersection for these two inequalities. Solving each inequality for h, you find that h > 9 or h < −3. Write a compound inequality for the graph shown below. Sometimes, an and compound inequality is shown symbolically, like [latex]a-3[/latex] has solutions that continue all the way to the right. Correct. In the following video, you will see an example of solving multi-step absolute value inequalities involving an OR situation.
