Fill in the table using this function rule y = 4x + 3

Which triangles area would be calculated using the trigonometric area formula

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.

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14
