Lesson 6-2 Objective: Solve inequalities using multiplication or division.

Example 2-4a 12 s ≥ s ≥ 5

Example 2-1a < 12 g 3 (3) g < 36 Multiply both sides by 3

Example 2-1b Answer: n ≤ 12Answer: p < 4

RULE: When multiplying or dividing by a switch the direction of the inequality symbol: When multiplying or dividing by a negative number, switch the direction of the inequality symbol: EX: EX: ≥ becomes ≤ ≥ becomes ≤

Example 2-5a -8 q < q > -17 Since we divided by -8, switch the !

Example 2-2a Multiply both sides by the reciprocal Since we multiplied by – 4/3, switch the ≤ to ≥ ! d ≥ -8

Example 2-5b. Answer: z < -16Answer: m ≤ -9
