1.5 Equations and Inequalities

Absolute Value: A number’s distance from zero on the number line. Remember: Distance is always POSITIVE!

Find the absolute value of each expression.

Solving Absolute Value Equations To solve |ax+b| = c : ax+b = c or ax+b = -(c) Example: |3x| = 15 3x = 15 or 3x = -(15)

Solving Absolute Value Equations Solve: |x| = 3 Solve: |x+1| = 6 Solve: |x| = -4
