1. Learning Targets I will be able to… *Solve absolute value equations *Decide if an absolute value equation has no solutions or infinite solutions

2. The distance between x and 0 3 3

3. Remember: The quantity inside the absolute value could be positive or negative.

5. x - 4 = 6 and -(x - 4) = 6 -x + 4 = 6 -x = 2 x = 10 and x =-2 This means that 10 and -2 are 6 units away from 4. 6 6

6. x + 7 = 3 and -(x + 7) = 3 -x - 7 = 3 -x = 10 x = -4 and x = -10 Meaning: -10 and -4 are 3 units away from -7. 33

8. Why is the absolute value of a number never negative?
