Solve and Graph Compound Inequalities

Lets keep the system working and show learners the three ways to solve linear systems of equations. Each method includes step-by-step instructions to work their way through the problem. The same problem is used for each method to show...

Although graphing a linear inequality on the plane is but a few steps added onto the graphing of a linear equation, for many learners the logical leap is quite intimidating. This approachable PowerPoint presentation breaks graphing...

One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

The teacher shows how draw a number line and graph an inequality using an open circle. She also shows how to graph a set of numbers on a number line.

Find the perfect amount of water for lemonade. Scholars solve the famous problem of measuring four liters of water using a three-liter container and a five-liter container. An interactive allows users to see each step of the solution.

Is the boundary line part of the graph of an inequality? Here's a hint: the sign of the inequality holds the answer! Are the brain cells firing up trying to figure out what that means? Watch this video as the instructor graphs the...
