moses makes a school spirit flag he has 1/3 as many yards of red fabric as blue fabric he buys 2 2/3 yards more red fabric Now he has equal amount of red and blue fabric use x to represent the amount of blue fabric which equation could you use to find the amount of red fabric moses has

f(x) = y

f(-3) = -5

step-by-step explanation:

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
