Answer:
Triangles ABC and DCB are congruent by SAS
Step-by-step explanation:
Angle CAB is congruent to angle CDB. Side DB is congruent to side AC. Then Ab is congruent to side CD.
Initial fee charged by Joe's canoe = $20
Hourly charge of Joe's canoe = $4
Hourly charge of Callie's canoe = $14
No initial fee is taken by Callie's canoe.
Let us assume the number of hours after which both places charges will be the same = x hours
Then
20 + 4x = 14x
20 = 14x - 4x
20 = 10x
x = 20/10
= 2
So after 2 hours the charges taken by both of them will be the same. I hope the procedure is easy and clear enough for you to understand.
To find
, you can switch the "x" and "f(x) or y" in the equation.
![y = \sqrt[3]{x-2}+ 8](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%5B3%5D%7Bx-2%7D%2B%208)
![x = \sqrt[3]{y-2}+8](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B3%5D%7By-2%7D%2B8)
Now you need to isolate the "y"
Subtract 8 on both sides
Cube ( ³ ) each side to get rid of the ∛
![(x-8)^{3} = (\sqrt[3]{y-2}) ^{3}](https://tex.z-dn.net/?f=%28x-8%29%5E%7B3%7D%20%3D%20%28%5Csqrt%5B3%5D%7By-2%7D%29%20%5E%7B3%7D)
Add 2 on both sides
