Question

Please help fill in each black so that the resulting statement is true.

Answer 1

(x^2 + 4x) + (y^2 - 18 y) - 5, complete the square on on x by adding to both sides.

Explanation:

Answer 2

The 4th answer: ((x1+x2)/2 , (y1+y2)/2)

Explanation:

To find the midpoint of a segment, you get the average of the x intercepts and y intercepts. So for the x-intercept, add the x-intercepts and divide by 2 and for the y-intercept, add the y-intercepts and divide by two.

((x1+x2)/2 , (y1+y2)/2)
