4. SOLVE ABSOLUTE VALUE INEQUALITIES 5.5

5. ABSOLUTE VALUE Absolute Value is the distance a number is from 0 on the number line. You can see from the diagram that |4|=4 and that the |-4|=4

6. ABSOLUTE VALUE Try these |5|= |-11|= |-2|= |6|= |-7|=

7. NOW TRY THESE |what|=2 |what|=7 |what|=4

8. SOLVING ABSOLUTE VALUE The key to solving absolute value problems is that you need to understand that what I s inside the absolute value can be positive or negative. Get the | | by itself Rewrite it as two equations, one with positive value and one with the negative value Solve each equation. There will likely be two solutions.

9. EXAMPLE Solve: |x|=7

10. EXAMPLE Solve: |x – 3|= 8

11. EXAMPLE Solve: 3|2x – 7|-- 5 = 4

12. EXAMPLE Solve: |3x + 5| + 6 = 2
