1. Warm ups – solve and graph 1. |x + 4| = 20 2. |4 – x| < 11 3. |2x + 3| < 7 4. |2x – 1| < -5

2. 7-6 Absolute Value “>” Objective: to solve open sentences involving absolute value and graph their solutions. Standards 3.0, 25.0

3. “>” = OR Great”OR” is “OR” |2y + 5| > 3 2y + 5 > 3 or 2y + 5 < -3 Change: Inequality sign Make number after “>” negative

4. Example 2 |8 - t| > 3 8 - t > 3 or 8 - t < -3 Change: Inequality sign Make number after “>” negative

5. Special Cases 1. |3y – 9| > 0 2. |y + 10| > -2 All numbers

6. TOO 1. |w + 8| > 1 2. |x - 9| > 0 3. |1 – 3y| > 2 4. |4t + 8| > -6

7. Working backwards… Given the graph, you come up with inequality involving absolute value… |x-middle #| Distance to middle and? or?

8. TOO Given the graph, you come up with inequality involving absolute value… |x-middle #| Distance to middle and? or?
