Answer:
Use a calculator its easier
Step-by-step explanation:
Answer:
for 9 miles = (9 x 1.50) + 2 = 15.5
For m miles = (m x 1.50) + 2 = 1.5m + 2
X+y=45
2x+5y=120
2(x+y=45)
2x+5y=120
-___________
-3y=-30
y=10 is the answer
Answer:
![\frac{AB}{A"B"} = \frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BA%22B%22%7D%20%3D%20%5Cfrac%7B1%7D%7B3%7D)
Step-by-step explanation:
Given
See attachment for ![\triangle ABC](https://tex.z-dn.net/?f=%5Ctriangle%20ABC)
Required
Determine the relationship between
and ![\triangle A"B"C"](https://tex.z-dn.net/?f=%5Ctriangle%20A%22B%22C%22)
The reflection over
does not have any impact on the side lengths of both triangles because reflection does not alter side lengths and angles
The dilation from
to
by scale factor 3 implies that:
![\frac{A"B"}{AB} = 3](https://tex.z-dn.net/?f=%5Cfrac%7BA%22B%22%7D%7BAB%7D%20%3D%203)
![\frac{B"C"}{BC} = 3](https://tex.z-dn.net/?f=%5Cfrac%7BB%22C%22%7D%7BBC%7D%20%3D%203)
![\frac{A"C"}{AC} = 3](https://tex.z-dn.net/?f=%5Cfrac%7BA%22C%22%7D%7BAC%7D%20%3D%203)
The above equations mean that options (c) and (d) are incorrect because A"B" does not correspond to BC
Take inverse of the above equations
![\frac{AB}{A"B"} = \frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BA%22B%22%7D%20%3D%20%5Cfrac%7B1%7D%7B3%7D)
![\frac{BC}{B"C"} = \frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7BBC%7D%7BB%22C%22%7D%20%3D%20%5Cfrac%7B1%7D%7B3%7D)
![\frac{AC}{A"C"} = \frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7BAC%7D%7BA%22C%22%7D%20%3D%20%5Cfrac%7B1%7D%7B3%7D)
means that (b) is correct
