Step-by-step explanation:
Given
f(x) = 12x + 2
f^-1(x) = ?
Now
Let y = f(x)
or y = 12x + 2
Interchanging the role of x and y
x = 12y + 2
x - 2 = 12y
y = <u>x </u><u>-</u><u> </u><u>2</u>
12
Therefore f^-1(x) = <u>x </u><u>-</u><u> </u><u>2</u>
12

Answer: -7.45
Step-by-step explanation -7 5/11 is -82/11 as an improper fraction, which is -7.45 in decimal form.
If I understand the question, you have to get n alone. in this case, you have to subtract 7 from both sides, resulting in n (is less than) -10
It was $930.
To over check, multiply it by 20% , you will get $186.
Hope this helps !
