Maya and her friends are planning a car wash event. Maya creates a function C(x) to model the group's costs for washing x cars and a function R(x) to model the revenue the group will make from washing x cars. The net profit the group will earn is represented by the function P(x) = -60 + 4.5x, which is equal to R(x) - C(x). Select the two functions that could represent the cost and revenue for the car wash.

How do you find the area of this triangle.

Malia is observing the velocity of a cyclist at different times. after two hours, the velocity of the cyclist is 15 km/h. after five hours, the velocity of the cyclist is 12 km/h. part a: write an equation in two variables in the standard form that can be used to describe the velocity of the cyclist at different times. show your work and define the variables used. (5 points) part b: how can you graph the equations obtained in part a for the first 12 hours? (5 points) if you can try and make this as little confusing as you can
