Graph: x < 2 x ≤ -2 x > - 4 x ≥ 3

When you multiply or divide by a negative number, you must flip the inequality symbol!!!

-2x + 7 < x < x > -5

2x + 3 < 5 OR x < x < 1 4x – 2 > x > x > 3 x 3

-2 ≤ 3x – 8 ≤ ≤ 3x ≤ ≤ x ≤ 6

The high temperature on a certain day was 98°F and the low was 78°F. Write a compound inequality that models the range in temperatures. 78 ≤ x ≤ 98

x  3x  3 x  2   5 x  2   5 x  7 Solve | x  2 |  5 The equation has two solutions: 7 and –3.

x + 5 can be any number between -6 and < x + 5 < < x < 1

Positive x – 4 > x > 7 Negative x – 4 < x < 1 x – 4 can be anything bigger than 3 or smaller than -3. OR x > 7 OR x < 1
