Answer:
28
Step-by-step explanation:
The initial number n must be a multiple of 4 (otherwise n/4 will not be an integer) and must be bigger than 0. Therefore if the initial number is less than 28 then it should be a number in the next list: 4, 8, 12, 16, 20 and 24, but from those options just 12 could give a second stop but not a third stop.
so the smallest number that allow three stops is 28 since:
Therefore 28 could not only stop three times but infinite times.

Answer:
![f^{-1}(x) = \frac{x-5}{2}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20%5Cfrac%7Bx-5%7D%7B2%7D)
Step-by-step explanation:
![f(x) = 2x+5](https://tex.z-dn.net/?f=f%28x%29%20%3D%202x%2B5)
Step 1) Replace y = f(x)
![y = 2x+5](https://tex.z-dn.net/?f=y%20%3D%202x%2B5)
Step 2) Exchange x and y
![x =2y+5](https://tex.z-dn.net/?f=x%20%3D2y%2B5)
Step 3) Solve for y
![x =2y+5](https://tex.z-dn.net/?f=x%20%3D2y%2B5)
Subtracting both sides by -5
![x - 5= 2y](https://tex.z-dn.net/?f=x%20-%205%3D%202y)
![2y = x-5](https://tex.z-dn.net/?f=2y%20%3D%20x-5)
Dividing both sides by 2
![y = \frac{x-5}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7Bx-5%7D%7B2%7D)
Step 4) Replace ![y = f^{-1}(x)](https://tex.z-dn.net/?f=y%20%3D%20f%5E%7B-1%7D%28x%29)
![f^{-1}(x) = \frac{x-5}{2}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20%5Cfrac%7Bx-5%7D%7B2%7D)
Answer:
-√5/2
Explanation: I took the quiz.
Answer:
China should trade Aircraft to Shirt and American should trade shirt to Aircraft.
Step-by-step explanation:
We should make a comparison table between two country
China America
1 Aircraft 40000 100000
1 Shirt 4 2
It is clear that China's labor productivity in aircraft production is more outstanding than America and America's labor productivity in shỉrt production is better.
So China should trade Aircraft to Shirt and American should trade shirt to Aircraft.
