Homework Answers

Answers to problem sets from textbooks in a variety of subjects including Math, Biology, and Chemistry.

Prentice Hall California Algebra 2 Answer Key Page 76 Problem 9 Section 2.3 +  

9. Yes, constant of variation = 12

The constant of variation is another term for the slope of the line which the equation maps.

California Algebra 2 Answer Key Prentice Hall Section 2.3 Page 76 Direct Variation Problem 8 +  

8. y is not directly variable to x

In this particular case there is no direct variation between y and x, meaning there is no constant of variation. y and x are related by some indirect means instead.

California Algebra 2 Answer Key Prentice Hall Section 2.3 Page 76 Direct Variation +  

This section deals with direct variation, the answers for problems 1-5 are as follows:

1. The constant of variation is 2
y = 2x
2. The constant of variation is -3
y = -3x
3. y is not directly varying with the value of x
4. The constant of variation is 1/3
y = 1/3x
5. The constant of variation is 7
y = 7x
6. y is not directly variable to x
7. The constant of variation is -2
y = -2x

Algebra 2 Answer Key Glencoe McGraw-Hill California page 43 problem 7 +  

7. -2 < x < 2

The answer to this problem essentially states that x is between 2 and negative 2, establishing limits upon the domain of x.
