The scale factor used to create the dilation is 3
You can easily find out by counting the sides
The coordinates of the pre-image are
(-2,-1) , (-2,1) , (-5,1)
the vertical line counts to 2 boxes
the horizontal line counts to 3 boxes
The coordinates of the image are
(4,-1) , (4,5) , (-5,5)
the vertical line counts to 6 boxes
the horizontal line counts to 9 boxes
= 3
= 3
The scale factor is 3
If the top number the numerator is bigger than the denominator then you would have a fraction that can be turned into a mixed number.
if it is less then it is a fraction.
Answer:
2 miles
Step-by-step explanation:
Given that :
Distance from home to store and back = 1/2 mile
In a week :
Number of times he walked from home to store and back = 1 time
Number of times she rode to store and back = 3 time
Note distance does not change whether she rode or walked:
Hence,
miles walked = 1/2 miles * 1 = 1/2 miles
Miles biked = 1/2 miles * 3 = 3/2 miles
Total Number of miles :
(1/2 + 3/2) = (1 + 3) /2 = 4/2 = 2 miles
