The difference of "x" and 7 is "-2"

x-7=-2

or, x=-2+7

or,x=5

the value of x=5 makes the difference of x and 7 ...

-2

x=5

Step-by-step explanation:

x=7-2

x=5

the value of x that subtract 2 from 7 is equal to 5

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
