  1. Solve & Graph Absolute Value Inequality

  2. Remember … Simplify the following: 1. |-5| = 2. |5| = 3. |8 + (-8)| = 4. |8| + |-8|= 5 5 |0| = 0 8 + 8 = 16 What does absolute value mean? The distance from zero.

  3. Solve & Check: |2m – 4| = 8 Solve: |2m– 4|=8 -8 = 2m - 4 2m – 4 = 8 OR +4 + 4 -4 = 2m +4 +4 2m = 12 . 2 2 . 2 2 -2 = m m = 6 Check: |2(6) – 4| = 8 |2(-2) – 4| = 8 |12 – 4| = 8 |-4 – 4| = 8 |8| = 8 |-8| = 8 ✔ ✔ 8= 8 8= 8

  4. Solve & Check: |3n +2| - 5 = 4n |3n+ 2| - 5 = 4n Solve: • + 5 +5 • |3n + 2| = 4n + 5 -(4n + 5) = 3n + 2 OR 3n + 2 = 4n + 5 -4n- 5 = 3n + 2 -4n - 2 -4n - 2 -n = 3 -3n + 5 -3n + 5 -7n = 7 ✗ n = -3 n = -1 Check: |3(-1) + 2| - 5 = 4(-1) |3(-3) + 2| - 5 = 4(-3) |-9 + 2| - 5 = -12 |-3 + 2| - 5 = -4 |-1| - 5 = -4 |-7| - 5 = -12 1 - 5 = -4 7 - 5 = -12 ✔ -4 = -4 ✗ 2 = -12

  5. What does absolute value mean?
