Find the midpoint of A and B where A has coordinates (-5,3) and B has coordinates (3,-1).

(-1,1)

Step-by-step explanation:

The midpoint of 2 points (a,b) and (c,d) is:

((a+c)/2,(b+d)/2)

You plug in the values (a = -5, b = 3, c = 3, d = -1), and get:

(-2/2,2/2)

Which simplifies to

(-1,1)

a: 1/6, j: 1/4

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
