1=-20+x i just need yall to show me the work .

Let's solve your equation step-by-step.

−1=−20+x

Step 1: Simplify both sides of the equation.

−1=x−20

Step 2: Flip the equation.

x−20=−1

Step 3: Add 20 to both sides.

x−20+20=−1+20

x=19

Hope this helps. :)

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

according to egenuity the answer is
