The coordinate (-2,5) is a solution to -x+ 5y= 37 true false?

Plugging the values in, you get 2+25=37. This is not true, so the answer is false.

False

Step-by-step explanation:

if you plug in (-2,5) into -x+5y=37 you get 27=37 which is not true

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
