Section 1.7 continued Solving Absolute Value Inequalities

In absolute value inequalities: If the absolute value is < or ≤ then it is a compound inequality joined by the word “and”. If the absolute value is > or ≥ then it is a compound inequality joined by the word “or”.

5.) Solve:  x + 2  > 5 Absolute value: 2 answers (±) > Joined by “or”

6.) Solve:  5x + 2  - 6 < 22 Absolute value: 2 answers (±) < Joined by “and”

7.) Solve:  2x - 2  ≤ - 2

8.) Solve:  2x  ≥ x - 1
