Which ordered pair is in the solution set of 0.5x - 2y ≥ 3?​

C

Step-by-step explanation:

The answer is c because when 2, -1 is plugged into the equation, you get

.5(2) - 2(-1) >/= 3

when solved -

1 + 2 >/= 3 -

3 >/= 3

and this is in the solution set because three is equal than or greater to three

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
