1.5 Solving Inequalities

Key Concept

Examples

You Try

Key Concept Multiplying or dividing each side of an inequality by a positive number does not change the truth of the inequality. However, multiplying or dividing each side of an inequality by a NEGATIVE number requires that the order of the inequality be REVERSED.

Key Concept

Examples Solve each inequality. Then graph the solution set on a number line. 1.3a + 7 ≤ < 3q – 3n > 7n 4.3x ≥ –9 5.4b – 9 ≤ 7
