My answer was 56/27. Here is the work I did.
Old coordinate
As center of dilation is origin the scale factor only multiplied with B
So
new coordinate
B'
- 1/2(2,-6)
- (2/2,-6/2)
- (1,-3)
1. 30 MPH
(divide hours (4.5) from miles (120))
2. $55.80
(divide fencing per cost (8) from cost (12.40) to get how much it costs per foot (1.55) then multiply it by how much feet you need (36))
The answer is D: 16,800 because you multiply the principal ($6,000), rate (7%), and time (4 years) to get the interest
