What is 2x-6=x+4 I need help breaking down

x=10

Step-by-step explanation:

2x-6=x+4

We subtract x from both sides, to cancel it out from the right side

2x-x = x and x-x = 0

x-6=0+4

x-6=4

add 6 to both sides, since 6+-6 = 0 (to isolate x on the left side)

-6+6 = 0

4+6 = 10

x=10

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
