To find the pre image you need to back track on the image. To get to the image you used (x-6,y+8). Now you need to use the exact opposite to get back to the pre image. For this you would change the signs to look like (x+6,y-8). Now we just apply this to (-4,1).
(-4+6,1-8)
(2,-7) should be the pre image point.
let's recall Cavalieri's Principle, <u>solids with equal altitudes and cross-sectional areas at each height have the same volume</u>, so even though this cylinder is slanted with a height = x and a radius = 8, the cross-sectional areas from the bottom to top are the same thickness and thus the same area, so its volume will be the same as a cylinder with the same height and radius that is not slanted.

Fast internet : 60 + 50.45m
Quick internet : 57.95m
to find the number of months they would be equal....set them equal to each other and solve for m, the number of months
60 + 50.45m = 57.95m
60 = 57.95m - 50.45m
60 = 7.50m
60/7.50 = m
8 = m.....so they will be the same at 8 months
