Every week for 40 weeks, Abeke earned $76 selling ice cream and 35$ delivering newspapers. Write a numerical expression to show how much money Abeke earned in 40 weeks.
Answers
Answer: 40 x (76+35)
Step-by-step explanation:
Given: Every week Abeke earned,
$76 by selling ice cream
$35 by delivering newspapers.
i.e. Total amount earned in 1 week = $ (76+35)
Now Total amount earned in 40 weeks = 40 x (76+35)
The numerical expression to show how much money( in dollars) Abeke earned in 40 weeks = 40 x (76+35)
We have to simplify it to get the total money earned in 40 weeks i..e. $4440.

Which function is the inverse of f(x)=9x-3
Answers
Answer:
The screenshot of my test is below
Step-by-step explanation:
The inverse function is [tex]f^{-1} (x)[/tex]=(x+3)/9.
The given function is f(x)=9x-3.
How to find the inverse of a function?Steps for finding the inverse of a function f(x).
Replace f(x) with y in the equation describing the function.Interchange x and y. In other words, replace every x with a y and vice versa.Solve for y.Replace y with [tex]f^{-1} (x)[/tex].Now, y=9x-3
Interchange x and y. That is x=9y-3.
Solve for y.
That is, 9y=x+3
⇒y=(x+3)/9
⇒[tex]f^{-1} (x)[/tex]=(x+3)/9
Therefore, the inverse function is [tex]f^{-1} (x)[/tex]=(x+3)/9.
