Step-by-step explanation:
y = f(X) = 3x - 7
3x = y + 7
x= (y +7)/3
f ^-1(x) = (x + 7)/3
Answer:
(Choice B)

-Combine like terms:
Answer:
The answer would be A. 3.3x
Step-by-step explanation:
3.3x can be broken down as 3.3.x
3.3 equals 9 and the 'x' is multiplied to 9.
Hence, it equals to 9x.
First off you need to convert the numbers into mixed numbers.
1 3/7 goes to 10/7
3 2/3 goes to 11/3
Then you multiply the numerators together:
10 * 11 = 110
Do the same for the denominators:
3 * 7 = 21
Then place it into a fraction and you make the fraction positive because the signs at the start are the same:
110/21
Then you can turn it into a proper fraction:
5 5/21
