Find the inverse, interchange the variables to solve for y
f-1 (x)=-
![\frac{8- \sqrt[]{_2(-8+x)} }{2} ,](https://tex.z-dn.net/?f=%20%5Cfrac%7B8-%20%5Csqrt%5B%5D%7B_2%28-8%2Bx%29%7D%20%7D%7B2%7D%20%2C)
Inlet pipe can fill the pool in 6 hours, means: every hour the pool is filled 1/6
a drain can empty the pool in 9 hours, means: every hour the pool is drained 1/9
If the inlet and the drain are both left open, every hour the pool is filled 1/6-1/9=1/18
It will take 18 hours to fill up the pool.

Step-by-step explanation:
7.74 + 9.281 = 13.055
8.2 x 4.3 = 35.26
32.5 x 6.88 = 223.6
37.4 ÷ 5.5 = 6.8
16.85 ÷ 5 = 3.37
35.75 + 55.50 x 2 = 146.75
