Two buses are driving along parallel freeways that are 4 miles apart with one bus heading east and the other heading west. Assuming that the bus traveling east drives a constant 70 mph and the bus traveling west drives a constant 62 mph, find the rate at which the distance between the busses is changing when they are 5 miles apart, heading away from each other.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
