Ch 3: Solving and Graphing Inequalities

About This Chapter

Watch online math video lessons and learn how to graph inequalities, systems of inequalities, absolute value inequalities and more. Each lesson is accompanied by a short multiple-choice quiz you can use to check your understanding of these inequalities topics.

Solving and Graphing Inequalities

Are inequalities something you don't fully understand? Perhaps you need to brush up on your skills in this area, or you feel like there's more you need to learn about inequalities. If so, you've come to the right place. We have a range of video lessons that will help you to gain skills and understanding in the area of inequalities.

What is an inequality? Do you know the answer? If not or if you're even slightly unsure, then let us teach you about where they exist in real life. We'll also help you to discover more about 'less than', 'greater than' and 2-variable and 1-variable inequalities. If you yearn to know more, we also cover systems of inequalities and compound inequalities. You may also check out what we have to teach on the topic of absolute value inequalities and set notation. We even provide you with the ability to practice solving absolute value inequalities problems.

If you are having troubles graphing inequalities, then we can help you with that, too. Take a look at what we have to share about how to graph 2-variable inequalities, including practice problems that will ensure that you completely understand the topic. Finally, learn about things like solid line vs. dotted line.

Learning inequalities will be straightforward, accessible, and even fun, thanks to our engaging animated video format. The video lessons are taught by subject matter experts and presented by professional video editors. Thanks for watching!

What is an Inequality?

1. What is an Inequality?

Deciding how to spend your money can be a tricky thing. Should you save it, invest it, or enjoy it? Learn how inequalities can help you make your decision!

How to Graph 1- and 2-Variable Inequalities

2. How to Graph 1- and 2-Variable Inequalities

So an inequality is just an equation with a less than or greater than symbol. But what is the difference between 1 and 2 variable inequalities? What does have a greater than or equal to symbol change? When do you use a number line instead of a coordinate plane? Get those answers here!

Set Notation, Compound Inequalities, and Systems of Inequalities

3. Set Notation, Compound Inequalities, and Systems of Inequalities

In this lesson, we'll explore the conditions of compound inequalities and learn how to express them using set notation and interval notation. Test you knowledge afterward with a short quiz.
