The data shown in the table is best described as

Suppose that x and y vary inversely. Write a function that models each inverse variation if x = 6 when y = 2.

Write a function that models for the following situation; z varies jointly with x and y and inversely with w.

Each pair of values if from a direct variation. Find the missing value.

(4, 10) , (8, y)

Each ordered pair is from an inverse variation. Find the constant of variation.

(5, 10)

Fundraising In a bake sale, you recorded the number of muffins sold and the amount of sales in a table as shown.

What is a function that relates the sales and the number of muffins?

Fundraising In a bake sale, you recorded the number of muffins sold and the amount of sales in a table as shown.

How many muffins would you have to sale to make at least $250.00?

Painting The number of buckets of paint n needed to paint a fence varies directly with the total area a of the fence and inversely with the amount of paint p in a bucket. It takes three 1-gallon buckets of paint to paint 84 square feet of fence. How many 1-gallon buckets will be needed to paint 120 square feet of fence?

Potential Energy On Earth with a gravitational acceleration g, the potential energy stored in an object varies directly with its mass m and its vertical height h.

What is an equation that models the potential energy of a 3-kg skateboard that is sliding down a ramp?

Potential Energy On Earth with a gravitational acceleration g, the potential energy stored in an object varies directly with its mass m and its vertical height h.

The acceleration due to gravity is g = -9.8 m/s^2. What is the height of the ramp if the 3-kg skateboard has a potential energy of -39.2 kg m^2/s^2?

Suppose that x and y vary inversely. Write a function that models each inverse variation if x = 10 when y = 5.

Write a function that models for the following situation; z varies inversely with the product of w and y.

The time required to process a shipment of goods at Wal-Mart varies directly with the number of items in the

shipment and inversely with the number of workers assigned. If 15,000 items can be processed by 8 workers in 10 hours, then how long would it take 12 workers to process 20,000 items?

Which equation represents an inverse variation?
