<em>Note: Your question seems a little bit ambiguous. So, I am assuming the given function f(x)=9x+7.</em>
<em>Thus, I am solving based on it. It would still clear your concept. </em>
Answer:
The inverse of f(x)=9x+7
Step-by-step explanation:
Given the function

A function g is the inverse of function f if for y=f(x), x=g(y)
Replace x with y

solve for y


Therefore,
The inverse of f(x)=9x+7 is:
i.e.

Answer:
B
Step-by-step explanation:
hope this helps with the work
Joyce and Tina had an equal amount of money
Lets x = # of days they spent money
Joyce spent $24 still had $64 left = 24x + 64
Tina spent $28 a day and spent all her money, no left = 28x
Both has equal amount of money so
28x = 24x + 64
Subtract 24x from both sides
4x = 64
Divide both sides by 4
x = 16
Answer:
Tina spent all her money in 16 days.
The answer is 327. Remember that when you multiply a number by ten, you move the decimal point to the right one place.
Hope that helped you.
