Chapter 1: Q19. (page 44)

Write an absolute value inequality for each of the following. Then graph the solution set on a number line.
all numbers greater than 8 or less than $- 8$

Short Answer

Expert verified

Absolute value inequality is $|x| > 8$

Solution set in number line is

Step by step solution

- Definition of absolute value inequality

For real numbers $a and b$ with b>0

Absolute value inequality is $|a| < b$ when $- b < a and a < b$ , and

Absolute value inequality is $|a| > b$ when $a < - b or a > b$

- Write an absolute value inequality

Let the real number be x

As $x > 8 or x < - 8$ so from definition, absolute value inequality is

$|x| > 8$

- Graph the solution set

For $x > 8 or x < - 8$ , number line starts from -8 to $- \infty$ and from 8 to $\infty$

Open circle on $- 8 and 8$ shows these points are not included in the solution.
