Solve for m.

3m+7/2=−2m+5/2

-1/5 = m

Step-by-step explanation:

3m + 7/2 = -2m + 5/2

subtract 5/2 from both sides

3m + 2/2 = -2m

simplify

3m + 1 = -2m

subtract 3m from both sides

1 = -5m

divide by -5

-1/5 = m

a

step-by-step explanation:

the answer is a

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
