Astudent government organization is selling christmas trees as a fundraiser. on friday, they sold 5 noble fir trees and 3 douglas fir trees for a total of $420. on saturday, 12 noble fir trees and 9 douglas fir trees were sold for a total of $1,080. what is the cost per tree for each type?
nevermind, i figured it out. noble fir trees= $60 and douglas fir trees= $40

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy

Suppose y varies directly with x. write a direct variation equation that relates x and y. then find the value of y when x=12 y=7 when x=3
