Ch 14: Graphing & Solving Inequalities

About This Chapter

Gain fluency and practice in solving and graphing inequalities by studying the lessons in this chapter. Review what an inequality is, what compound inequalities and systems of inequalities are, and strengthen your skills in working with them.

Graphing & Solving Inequalities - Chapter Summary

This chapter provides both instruction and hands-on practice in identifying, graphing, and solving inequalities. You will work with absolute inequalities, learn how to solve and graph them, and gain skill in translating between inequalities and mathematical sentences. The lessons teach you about:

  • Defining and graphing inequalities, and solving practice problems
  • Understanding sets, compound inequalities and systems of inequalities
  • Finding solutions to and graphing absolute inequalities, and completing practice problems
  • Making translations between math sentences and inequalities

Short, easy, expertly illustrated and well-presented lessons, coupled with self-assessment quizzes and a chapter test, all combine to form a powerful and comprehensive study guide that is as close to you as your smartphone or any device that allows online access. Each video lesson is accompanied by a fully transcribed version, and key terminology is set off in bold print for rapid identification and reference. Our instructors and subject-matter experts are available for questions upon request, so help is always at hand.
