Ch. 5 Solving Inequalities

by James Flowers

Vocabulary

Remember, the terms used will be the operation or direction the inequalites will go.

Have you read: greater, lesser, increase, decrease, most, at least, no more than?

These all relatee to the direction of the inequality.

Remember Inverse Operations, thats what we will use to solve...
