Answer: f^{-1}(x) = 3-x/3
Step-by-step explanation: Let y = f(x) and rearrange making x the subject, that is...
1. y = - 3x + 3 ( add 3x to both sides )
2. 3x + y = 3 ( subtract y from both sides )
3. 3x = 3 - y ( divide both sides by 3 )
4. x = 3-y/3
Change x back into terms of y
f^{-1}(x) = 3-x/3
Answer:
Rounded to the nearest tenth: 2,252.5
Step-by-step explanation:
This number can't be a whole number since there is a decimal.
8/9 = 0,8
0,8/4 = 0,2
so each piece was 0,2 yard long
Answer:
403.75
Step-by-step explanation:
we can write the following equation
.75m+145=price
we just need to plug in 345 for m
.75*345+145=price
put this into a calculator and get 403.75
This is the answer!! Also I use Photomath to help with my hw!
