Inequalities & Equations

​The only difference between solving equations and inequalities is this:

Example: 12 - 8x > 4; when you multiply or divide by a negative coefficient; the sign must be flipped around.

-8x > -8; divide both sides by -8; the solution is x < 1

Try these: -4x - 3 < 5;

Inequalities

1. Best to complete Khan, classwork, and Test #1 before beginning this section

2. Test # 2, Inequalities is next Friday (Feb. 17). Classwork given Monday

3. Don't forget about test zero; multiplication tables. Unlimited practice and two shots at the test.
