Answer:
A. 
Step-by-step explanation:
Given:
Volume of the cylindrical container before dilation, 
Scale factor of the dilation, 
Therefore, the volume of the dilated cylinder is given as:

Plug in 1 gal for
and
for SF. Solve for
. This gives,

Therefore, the volume of the dilated cylinder is
gallons.
8/10
4x2=8
5x2=10
this is how you know they are equal
Add 2 to each x coordinate because it is moving to the right. For example. For (2,1), add 2 to the x coordinate (2). 2+2=4, so the prime point would be (4,1).
Just divide those two number on how you usually do it but with a decimal this time.
