Since the function depends on 4 variables (assuming that p and P are the same variable), the full graph would require 5 dimensions. You can, however, graph something like a cross-section for the graph, in the sense that you keep most of the variables constant, and study the dependency of the function on a single variable at a time.
25y2 - 9 = 0Factor the expression on the left side of the equation:(5y + 3) (5y - 3) = 0The equation is a true statement if either factor is zero:5y + 3 = 05y = -3y = -3/5and5y - 3 = 05y = 3y = 3/5
Two equations. x+y=56000 .07x=.05y Solve both of these equations simultaneously and it will be the answer. x+(.07/.05 x)=56000
