Course: Algebra I / Elementary Algebra
Topic: Linear Equations and Inequalities
Subtopic: Solving Compound Inequalities


Compound inequalities means to combine two or more inequalities together. There are three ways to do this.

The final answers to these compound inequalities will usually be written in interval notation, but could be given in interval notation or graphed on a number line.

Treat this section as an introduction to compound inequalities. This topic will be covered more thoroughly in a college-level course.


By the end of this topic you should know and be prepared to be tested on:


Define: compound linear inequality, intersection ∩, union ∪

Text Notes

Many textbooks cover business applications of inequalities at this time. If yours does you can SKIP the business applications, revenue function, cost function, profit function, and all of the graphing stuff! You will NOT be tested on these topics in this level course.

If your textbook covers equations/inequalities that contain absolute values you may SKIP these problems! You will NOT be tested on these topics in this level course.
