Use the drawing tool(s) to form the correct answers on the provided graph. Graph the lines that represent the following system of linear equations.

2x + 1.5y = -60
2x + y = -50

Then, mark the point on the graph that represents the solution to the system.

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

care to share were the trapezoid shown is ?
