Problems 7-9 involve exponents, inequalities, and geometric figures (diameter and radius), all of which Sal explores eagerly. After misreading one problem, he takes care to correct his mistake, showing students how important it is to...

With pen in hand and diagrams at the ready, Sal demonstrates problem-solving and test-taking skills in this informative video. Problems 7-9 involve inequalities, linear equations, and measuring angles in a right triangle.

Inequalities mean not equal—and are not difficult at all. An engrossing YouTube video teaches scholars how to write inequalities from verbal statements. It also explains how to determine if a value is a solution to an inequality and how...

When you graph an inequality on the coordinate plane you will get two half-planes. The line itself is called the boundary line. One of the halves is called the closed half-plane and the other half is called the open half-plane. How do...

Do you know how to graph a linear equation? If you do then graphing an inequality will not be a problem for you. There are a couple of differences: is the line solid or dashed, and which half plane do you have to shade. Watch this video...

Divide decimals to solve this inequality! Learners can watch the instructor in this thorough video as she works through an inequality that contains decimals. This resource is appropriate for teaching, reinforcing, or reviewing the concept.

If your class is studying inequalities, consider this video. The focus is on solving a decimal inequality that has negative numbers in it. A lecturer works through an example problem, commenting on the steps and properties necessary to...

Go over how to solve a compound inequality and graph it with this video. The video is clear and concise. A lecturer solves a compound inequality and graphs it on the spot, explaining each operation in detail. Great for in-class or...

What makes an expression an inequality? Well, it would be considered an inequality if the expression has a greater than symbol, a less than symbol, a greater than or equal to symbol, or a less than or equal to symbol. This would mean...

Check to see if a given ordered pair is a solution to an inequality. Just plug the given values into the given inequality and do the math. If the resulting statement is true then the given ordered pair is a solution. If the statement is...

In this video, you will learn how to solve inequalities in algebra that only have one variable. You will learn that solving inequalities is very similar to solving equations and many of the same rules apply. After we arrive at the...

This lesson will teach you the basics of absolute value including a definition of absolute value, examples of absolute value in real life situations and practice solving absolute value equations.

This lesson will teach you the basics of absolute value including a definition of absolute value, examples of absolute value in real life situations and practice solving absolute value equations.

In this lesson, students will learn Absolute Value Inequalities: Graphing Distance

Here we look at how to relate compound inequalities to real world problems.

This lesson will demonstrate how to solve a compound inequality that contains the word "or."
