Algebra: Solving Linear Inequalities

Mon, 22 Mar 2010 14:30:27 -0700

[NOTE: This video is only the first 23 minutes of the full lesson. Please visit my website to purchase/rent complete version]

This lesson consists of providing you with a Self-Tutorial on how to solve typical linear inequalities of the form: ax + b > c (any of these symbols: <, >, ≤, ≥ can be used).

The tutor goes over how to draw number line graphs. Also covered is the Double Inequality (a < x < b). Properties of Inequalities are reviewed. Answers are presented in Inequality Notation, Interval Notation, and Set Notation.

Compound Linear Inequalities are solved and graphed. Finally, English Phrases are translated into inequalities and some Word Problems are solved.

Algebra: Solving Linear Equations - Part 2: Applications - Sample 2

Mon, 22 Feb 2010 02:12:04 -0700

Part 2 of 2. [NOTE: This video is only a 12 minute portion of the full 3 hour lesson. Please visit my website to purchase complete version]

This lesson consists of providing you with a Self-Tutorial on how to solve typical linear word problems (story problems or applied problems). I will show you how to solve for a specific variable in formulas. I also discuss how to covert a repeating decimal into a fraction (which was skipped in Basic Math: Lesson 6 -"Fractions") and will teach you how to convert units of measurement.

Examples of word problems done include:

Finding a number based on certain criteria.
Word problems involving some geometry (triangle, rectangle, circle).
Age problems.
Mixture problems.
Money problems (story of my life!).
Rate-Time-Distance problems.
Percent Equations/problems.
Ratio and Proportion (concepts and solving problems, including similar triangles).
Problems dealing with Unit Price.
