Guided Lesson: Compound Inequalities - Theresa Joseph | Library

What is compound inequality?
A compound inequality is an inequality that combines two simple inequalities. Let's take a look at some examples.

Now try making a couple of compound inequalities of your own.

But what if the inequality is complex like
-5 ≤ x-4 ≤ 13
How can I represent this on a number line when x is not alone? 
Watch this video to figure it out!
