ABSOLUTE VALUE - Solving Inequalities

ABSOLUTE VALUE - Solving Inequalities

Author: Kate Sidlo
Description:

By the end of this tutorial students will be able to solve absolute value inequalities with one variable

Students will be able to graph absolute value inequalities on a number line using the two solution inequalities

 

This tutorial introduces students to solving absolute value inequalities following four simple steps:

1) Balance so the absolute value is alone
2) Write two inequalities (a positive absolute value and negative absolute value equation)
3) Balance the inequalities
4) Check your solution by substitution and/or number line

The tutorial uses a handful of examples to demonstrate the steps.
