Lesson 26 Solving Absolute Value Inequalities

Essential QuestionHow can you solve an absolute value inequality? Solving an Absolute Value Inequality AlgebraicallyEXPLORATION 1Solving an Absolute Value Inequality AlgebraicallyWork with a partner.Consider the absolute value inequality | x + 2 | 3.a. Describe the values of x + 2 that make the inequality true. Use your description to write two linear inequalities that represent the solutions of the absolute value inequality.b. Use the linear inequalities you wrote in part to find the solutions of the absolute value inequality.c. How can you use linear inequalities to solve an absolute value inequality?Answer:The given absolute value equation is:| x + 2 | 3

The following are the steps to solve the absolute value inequality:A) Isolate the absolute value expression on the left side of the inequalityB) If the number on the other side of the inequality sign is negative, then your equation either has no solution or all real numbers as solutionsC) Remove the absolute value bars by setting up a compound inequalityD) Solve the inequalities

c. How can you use a number line to solve an absolute value inequality?Answer:You begin the marking of the points on the number line by making it into separate equations and then solving them separately. An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative. You can write an absolute value inequality as a compound value inequality

EXPLORATION 1 Solving a Multi-Step Inequality Work with a partner.

Use what you already know about solving equations and inequalities to solve each multi-step inequality. Justify each step. Match each inequality with its graph. Use a graphing calculator to check your answer.a. 2x + 3 x + 5b. -2x + 3 > x + 9c. 27 5x + 4xd. -8x + 2x 16 < -5x + 7xe. 3 5x > -3x 6f. -5x 6x 8 8x xAnswer:a. 2x + 3 x + 5b. -2x + 3 > x + 9c. 27 5x + 4xd. -8x + 2x 16 < -5x + 7xe. 3 5x > -3x 6f. -5x 6x 8 8x xThe given graphing calculators are:Now,From the graphing calculators, we can observe that the graph is divided into 4 parts.The first part indicates +xThe second part indicates -xNow,

We can conclude that the solution to the given inequality is x -4The graph F) matches the solution of the given inequality

Question 2.How can you solve a multi-step inequality?Answer:The general procedure for solving multi-step inequality is as follows:a) Clear parenthesis i.e., Brackets on both sides of the inequality and collect like termsb) Addor subtract terms so the variable is on one side and the constant is on another side of the inequality sign

We can conclude that the given inequality has no solution

Algebra I focuses on solving quadratic functions using the quadratic formula and FOIL, as well as graphing parabolas and manipulating their appearance through changes made to the source equation. Other concepts that may be introduced at various points within Algebra I classes are statistics and probability, percent, and percent change. While not directly related to the overarching ideas of equations, functions, and graphs, these concepts may be taught in a way that mirrors the back-and-forth logic used to teach students about functions and their graphs. For instance, a focus when learning percents is how to convert a percent to a decimal and vice versa, and when expressing the probability of an event occurring, students also necessarily figure out the probability of the event not occurring. The mathematical concepts that students master in Algebra I form the core of their mathematical understanding in many later classes in math and the sciences.
