Determine the type of variation:DirectInverseNeither - 3. Multiple ChoiceWhich of the following represents indirect variation?y = kxy = k/xy = x/ky = mx + b
- 4. Multiple ChoiceIf y varies inversely as x and x=5 when y=20, then what is the constant of variation, k?12141006
- 5. Multiple ChoiceThe cost per person to rent a mountain cabin is inversely proportional (varies inversely) to the number of people who share the rent. If the cost is $36 per person when 5 people share, what is the cost per person when 8 people share?$22.50$57.60$1.11$12.50
- 6. Multiple ChoiceIs the given table a direct or inverse variation? What is the constant of variation?Direct, 12Inverse, 12Direct, 1/12Inverse, 1/12
- 7. Multiple ChoiceIf y = 15 when x = 32 find y when x = 12.40-405-5
- 8. Multiple ChoiceAssume y varies inversely with x. If x=7 when y=4, what is y when x=2 ?414728
- 9. Multiple Choicey varies directly with x.
y is 84 when x is 16. What is the constant of proportionality?y = (21/4)xk = 21k = 5.25k = 4/21 - 10. Multiple ChoiceIn a direct variation, y = 39 when x = 3.
