F(C) = 95C + 32...
F(C) is y.
y = 95C + 32
Switch Y & C.
C = 95y + 32
C - 32 = 95y
(C - 32) / 95 = y
In the inverse, y is F-1(C)
F-1(C) = (C - 32) / 95
Answer:
3.33333
Step-by-step explanation:
You have to put:
If 15 ------------- becomes 5
then 10--------- becomes X
like this type of rule says, you should do:
(10x5)/15= 3.33333
4 thousands = 4,000
21 tens = 21*10 = 210
210 + 4,000 = 4,210
Answer: 4,210
The is number 3 or c. I hope this helps.
