Warm UpSolve the following equation—words, graph, and solution.

1.

2. Solve the following inequality.

1.6 Compound InequalitiesA compound inequality consists of inequalities joined with the word AND or the word OR.

You must solve each part separately.

“AND” InequalitiesSo far, you know…

But sometimes we’ll have inequalities with three parts…

Our goal is still the same:

Get the alone on the LEFT!

Ticket Out The DoorUse the ideas you learned today in class to…

1. AND Example Create an original problem Solve Graph (make sure the graph looks correct!!!)

2. OR Example Create an original problem Solve Graph (make sure the graph looks correct!!!)
