9.3. Absolute Value Inequalities
Solving an inequality with an absolute value means finding values for x that make the inequality true.
Type the inequality as given in the problem with one inequality per line.
Examples
Solve each absolute inequality.

Calculator solutions
1) Enter the expression: |2x - 1| by using the absolute value key |x|.
Type the less than sign ( < ) by tapping the open parentheses " ( " three times.
2) Enter the expression: |3x - 4| > 5.
Type the greater than sign ( > ) by tapping the closed parentheses " ) " three times.
3) Enter the expression: 3|x - 4| > 15 as "3|x - 4| >= 15."
Type the greater than or equal to sign ( > ) by first typing the greater than sign and then the equals sign " >= ".
4) Enter the expression: 3|x - 4| < 15 as "3|x - 4| <= 15."
Type the less than or equal to sign ( < ) by first typing the less than sign and then the equals sign " <= ".
