Answer:
f^-1(x) = 9(x+2)
Step-by-step explanation:
To find the inverse function, exchange x and y and then solve for y
y = 1/9 x -2
Exchange x and y
x = 1/9 y-2
Solve for y
Add 2 to each side
x+2 = 1/9 y-2+2
x+2 = 1/9y
Multiply each side by 9
9(x+2) = 9*1/9y
9(x+2) = y
The inverse function
f^-1(x) = 9(x+2)
Answer:Alex earned $12
John earned $36
Step-by-step explanation:
j=3a
a+3a=48
4a=48
a=48/4
a=12
j=36
20% in fraction form is....
1) 20 is the percent
2)to put it in a fraction form.......
3) you need to divide it by 100.
4) 20 /100 equals 0.2
5) 0.2 says it's out of 2/10
6) if you want to simplify you can so go ahead: 2/10 >>> (turns into) 1/5
7) 1/5 is your answer...
8) PLEASE GIVE THIS A THANKS AND THE BRAINIEST ANSWER/CROWN...IF NOT...WELL PLEASE DO :) :) :) :) :D :D :D ;D:D
