1. Absolute Value in Open Sentences
Chapter 3
Section 3.5

2. Objective
Students will solve equations and inequalities involving absolute value.

3. Concept
You learned that a is the distance between the graph of a number a and the origin (0) on a number line.

4. Concept
x = 3 means x is 3 units from 0 x = -3 or x = 3 x < 3 means x is less than 3 units from 0 -3 < x < 3 x > 3 means x is more than 3 units from 0 x < -3 or x > 3

5. Concept
To solve absolute values in open sentences, set the absolute value part =, <, or > to the positive and negative of the number. Example: x + 4 = 1 x + 4 = -1 x + 4 = 1

6. Example
Solve and Graph x – 2 = 4

7. Example
Solve and Graph x + 1 < 3

8. Example
Solve and Graph x – 3 > 2
