F(c)= 9/5c+ 32 I just don't understand how to find the inverse of the function
Viefleur [7K]
F = 9/5 C + 32
- 32 -32

subtracting - 32 from both sides

F - 32 = 9/5c
5/9 F -32 = 5/9(9/5)C

Invert 9/5 to 5/9 multiply to both sides

5/9F - 32 = C

The answer is 5/9F-32 = C

If frank has 380 condoms and he uses 180 in two weeks and by the 4th week he has 2 left how many did he use in 2 weeks (btws thi
anastassius [24]

You have said that he used 180 in the first two weeks.

That left him with 200 at the end of the first two weeks.
Then you said that he had 2 left after another 2 weeks.
So during those 2 weeks, he used (200 - 2) = 198 in the 2nd 2 weeks.

What we all expected has not happened at all:  Frank is not slowing down !

But, even so, we have to ask ourselves just what Frank is doing with them all.

Nobody can blame you for wondering.
