Below are the steps to solve an equation:

step 1: |x − 4| + 1 = 8
step 2: |x − 4| = 8 − 1
step 3: |x − 4| = 7

which of the following is a correct next step to solve the equation?
a x − 4 = −7
b x + 4 = −7
c −x − 4 = 7
d x + 4 = 7

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

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
