Find the value of x. PLEASE HELP

I need to show my work.

x-60

Step-by-step explanation:

Well the expressions lie on a straight line so I know that both of the added together will equal 180.

So the equation looks like this-(x-1+2x+1=180)

So when I substitute 60 in the equation it looks like this-(60-1+2(60)+1=180)

To solve-60-1+120+1::59+120+1::60+120

180

a - base

b - exponent

so,

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
