answer:

35 - 7y

step-by-step explanation:

a product refers to multiplication, so we have to multiply 7 and y, and then subtract that from 35.

answer:

the answer is 7y-35

step-by-step explanation:

it asks you for the product of 7 and y which is, 7y after you put -35.

addition

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
