This video involves solving linear inequalities. This video starts off with a black screen because the narrator uses it as a 'chalkboard' by using the Paint Program.

An instructor shows why we flip the sign when multiplying or dividing by a negative when solving inequalities. He uses a flip chart and shows several examples including both inequalities and word problems.

In this video, Sal Khan explores how to write inequalities using a word problem (that involves a touring band). Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Awa...rd in Education. (02:01) There is a lot of information on the screen--the viewer may want to open the video to 'full screen.'[more]

This lesson consists of providing you with a Self-Tutorial on the basics of equalities and inequalities. I go over how to write results in interval notation, inequality notation, and set (set-builder) notation. I also explain in the printed notes how... to use your graphing calculator to help you make comparisons between numbers.[more]

This video shows graphing linear inequalities, linear programming, solving systems in three variables, matrix addition and subtraction, and using matrices to represent translations. (10:37)

Advanced Algebra Concept Exam #7 (concepts 9-13). This video discusses direct variation, linear modeling, graph and translate absolute value functions and inequalitites, graph linear and absolute value inequalities, and solving linear systems: subst...itutions and eliminations. (14:42)[more]
