Jeanne is opening a shop and plans to sell cakes. the cost, in dollars, of producing x cakes can be represented by c(x). the revenue, in dollars, brought in by selling x cakes can be represented by r(x). jeanne claims that she will need to sell 300 cakes in order for the cost of producing cakes to equal the revenue brought in by selling the cakes. select three methods that can be used to prove jeanne’s claim. a. graph y = c(x) and y = r(x), and show that the intersection point is (k, 300) for some k. b. graph y = c(x) – r(x) and y = 0, and show that the intersection point occurs when x = 300. c. graph y = c(x) – r(x), and show that the x–intercept occurs at the point (300, 0). d. graph y = c(x) and y = r(x), and show that the intersection point is (300, k) for some k.

Drag the tiles to the table. the tiles can be used more than once. nd g(x) = 2x + 5 model a similar situation. find the values of f(x) and g(x) let's say that the functions f(x for the given values of x. fix)=5(4) * g(x) = 2x+5

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
