## Math 098 - Chapter 3&4 Study Guide

1. Solve each equation algebraically. Six parts. Look at problems 3.1.31 - 3.1.65 (4 parts), 3.8.13 - 3.8.17 (1 part), and 3.8.55 - 3.8.71 (1 part)
2. Solve the formula for the given variable. Two parts. Look at problems 3.3.3 - 3.3.31.
3. Application problem. Look at problems 3.3.53 - 3.3.57. (Directly from text with numbers changed)
4. Application problem. Directly from text with numbers changed. Be sure you know the formulas from section 3.5. Look at problems 3.5.19, 25, 39, 41, 47, 57
5. Solve the inequality algebraically. Write the solution with interval notation and graph the solution set on the number line. Five parts. Look at problems 3.6.47 - 3.6.77 (1 part), 3.7.33 - 3.7.45 (1 part), 3.7.61 - 3.7.75 (1 part), 3.8.91 - 3.8.109 (2 parts)
6. Determine three solutions of the given equation and sketch the graph. Look at problems 4.1.39 - 4.1.53

8. Write an equation of the line having the given slope and containing the given point. Look at problems 4.4.21 - 4.4.35
9. Write an equation of the line that contains the given pair of points. Look at problems 4.4.39 - 4.4.51
10. Graph the inequality. Look at problems 4.5.19 - 4.5.37

### Notes:

• All problems except for the application problems are directly from the odd numbered exercises in the text.
• The applications problems are very similar to problems in the text, only the numeric values have been changed.
• The homework for Chapter 4 was incorrectly listed on your assignment sheet. The instructor mis-typed the information. Please note the corrected assignment below.
