Algebra 1 Section 6.4 Solve absolute Value Equations and Inequalities Recall: The absolute value of a number is the distance a number is from the origin on a number line. Solve: |x| = 4 Solve: | 2x – 3 | = 9

Absolute Value Inequalities | x | < c means –c < x < c (All numbers less than c units from the origin on a number line) | x | > c means x<-c or x>c (All numbers more than c units from the origin on a number line)

Solve and graph | x| < 3 |x – 2 | < 6

Solve and graph | x| > 5 |x + 4 | > 7

Solve and graph | 3x – 6 | + 2 < 14 |1/2 x – 5 | + 2 > 6
