If f (x) = one-ninth x minus 2, what is f>1(x)

Mathematics
1 answer:

Answer: f-1(x) = 9x + 18.

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y =  x - 2 ( add 2 to both sides )

y + 2 =  x

Multiply through by 9 to clear the fraction

9y + 18 = x

Change y back into terms of x

(x) = 9x + 18

Somebody please help with this math problem.19=4b-13
Veronika [31]
Start by adding 13 to both sides

19 = 4b-13
<span>19+13 = 4b-13+13
</span>32 = 4b
4b = 32

Then divide both sides by 4 to isolate b

4b = 32
4b/4 = 32/4
b = 8

So in the end, b = 8
