Chapter 6.2 Solving Inequalities Using Multiplication or Division Mr. Beltz & Mr. Sparks

P. 330 Goal: Solve and graph one-step inequalities in one variable using multiplication or division.

Using Multiplication a < 10 4 *4 *4 a < 40

Using Division 4x > x > 5

Multiplying & Dividing by Negative Numbers When you multiply or divide by a negative number, you must reverse the inequality sign. -4x > x < -5

Division with Negative Numbers a < *-4 *-4 a > -40

Practice P #1-10 Show your work.
