2-10 Solving Inequalities by Multiplying or Dividing
What You’ll Learn To solve inequalities by dividing To solve inequalities by multiplying
2
Example 1: Solving inequalities by Dividing
Solve – 3y < -27 -3y < -27 -3y/3 > -27/-3 y > 9 Divide each side by -3 Reverse the direction of the symbol Because dividing by a negative simplify
3
Solve and graph each inequality
- 8m > -24 7n > - 21
4
Solve Inequalities by Multiplying
Solve y/-8 > 2 y / -8 > 2 y / -8 * - 8 < 2 * - 8 y < - 16 Multiply each side by – 8 Reverse sign Because multiplying by a negative Simplify
5
Solve and Graph Inequalities
k / -5 < - 4 p / - 7 > 6 m / 9 < - 6 Practice: Text page 119 # 4-19 Assign Practice 2-10 Review for test Re 2-8 to 2-10 Test Move to slope form
