Which methods could you use to calculate the x-coordinate of the midpoint of a horizontal line segment with endpoints at (0, 0) and (20, 0)? Check all that apply.

In this case,

→

Then divide by 2 to get 10. The value of the x coordinated of the midpoint is 10.

C, is really the only practical solution imo

Step-by-step explanation:

We are only doing the x coords here, so im going to leave the y values out of the midpoint formula.

I could write the midpoint formula, but its a lot easier to truly understand what it means. When youre taking the midpoint of a line, you want to know the middle, obviously, which means the average among the line. The average of anything is adding the two values then dividing them by 2.

In this case, it is 0 + 20 = 20. Then divide by 2 to get 10. The value of the x coord of the midpoint is 10.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
