1. Determine whether the points (-5,8) and (-5,-4) lie on the same horizontal or vertical line. Explain how you know. Then, find the length of the line segment that connects them. 2. Skye’s city is on a grid like the coordinate plane. He unicycles from point (11,15) to point (11, -12). How many units does he travel? Explain how you found your answer using absolute value.

51-50

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
