15.2 Inequalities in a Triangle (Practice)

# Compound inequalities

Sal solves the compound inequality 5x-3<12 AND 4x+1>25, only to realize there's no x-value that makes both inequalities true.

# Testing solutions of inequalities

A solution to an inequality makes that inequality true. Learn how to test if a certain value of a variable makes an inequality true.

# Graphing linear inequalities

Graph the inequality y > 2 - 2x

# Compound inequalities

Sal solves the compound inequality 3y+7<2y AND 4y+8>-48.

# One-step inequalities

In addition to solving the inequality, we'll graph the solution. Remember to swap if you mutiply both sides of the inequality by a negative number.

# Multi-step linear inequalities

Sal solves several multi-step linear inequalities.
