SOLVE ASAP! Given f(x) = -5x + 1, solve for x when f(x) = -4.

x = 1

Step-by-step explanation:

Substitute f(x) = -4 as we get:-

-4=-5x+1

-4-1=-5x+1-1 —> subtract both sides by 1

-5=-5x

-5/-5=-5x/-5 —> divide both sides by -5

1=x

Therefore x = 1

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

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
