For which pair of points can you use this number line to find the distance? A number line going from negative 2 to positive 8. Points are at 1 and 7. (–4, 1) and (7, –4) (–4, 1) and (–4, 7) (–1, –4) and (–4, 7) (–4, –1) and (–4, –7)

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

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed
