Given: F(x) = 5x-6 and G(x) = x - 4 (F • G)^-1 =

A. ( x + 10)/5

B. (x+26)/5

C. -5x+26

step-by-step explanation:

f

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

answer: 0.64

step-by-step explanation:

the answer is 21%.
