Today the cost of a gallon of gas is $2.65. every week for the next 10 weeks, it will increase by $0.05 a gallon. if you wrote a linear equation to model this situation, what would the slope be?

Suppose that the price p (in dollars) and the weekly sales x (in thousands of units) of a certain commodity satisfy the demand equation 4p cubedplusx squaredequals38 comma 400. determine the rate at which sales are changing at a time when xequals80, pequals20, and the price is falling at the rate of $.20 per week.

Anyone? 15m is what percent of 60m; 3m; 30m; 1.5 km?

50 plz, given the system of equations, match the following items. x + 3 y = 5 x - 3 y = -1 a) x-determinant b) y-determinant c) system determinant match the following to the pictures below.
