Find the slope of the line that passes through the points (2,-5)(7,1) ? step 1: (x 1,y1)

slope = (y2-y1)/(x2-x1)    (x1,y1) = (2,-5)  (x2,y2) = (7,1)

 = (1- (-5))/(7-2)

= (1+6)/(5

step-by-step explanation:

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
