Plot two points that are 7 units from Point D and also share the same 2-coordinate as Point D.

-4,8 and -4, -6

Step-by-step explanation:

The two plots that 7 units from point d and also share the same x- coordinate as point d are shown in the graph

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

answer: its the third option.
