These are the formulas you may need for the test:

The length (L) of a wall built in a day varies directly with the number of workers (W) on the job and inversely with the height (H) of the wall. If 8 workers can build a wall that is 6 feet tall and 20 feet long, what length of wall can be built with 11 workers that is 5 feet tall?

Determine the correct model (equation) for the following statement: “Weekly pay (P) varies directly with hours worked (H).”

A = (-2, 4), B = (4, 1) and C = (0, -2). What is the length of side AB?

If f(x) = 4x – 3, find the difference quotient,
