Question

1. Classify the situation as direct or inverse variation.

Super Shine Car Wash charges $13 per wash.
Direct variation or inverse variation

2.Classify the situation as direct or inverse variation.
Super Shine Car Wash charges $13 per wash.
Direct variation or inverse variation

3. xy = 8
Direct variation or inverse variation

4. y/x = 2.5
Direct variation or inverse variation

5.Classify the situation as direct or inverse variation.
The longer you drive, the greater the distance you travel
Direct variation or inverse variation

Answer 1

1. and 2. is the same question, so the answer to both is direct variation

3. Direct variation

4. Inverse variation

5. I believe it is Inverse, but I'm not 100% certain

Answer 2

1. and 2. Direct variation

3. Inverse variation

4. Direct variation

5. Direct variation

Explanation:

In direct variation if one variable increase the other one also increase

In inverse variation if one variable increase the other one decrease

1. and 2. Direct variation. As the number of washes increase the cost increase.

3.Inverse variation. If x increase, y has to decrease so that their multiplication remains the same

4. Direct variation. If y increase, x has to increase so that their division remains the same

5. Direct variation. As you spend more time travelling the distance you travel increase
