Aschool is planning for an addition in some open space
next to the current building. the existing building ends at
the origin. the graph represents the system of equations
that can be used to define the space for the addition. what
is the system of equations that matches the graph?

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.

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29
