Answer:
The answer is 2nd point
Step-by-step explanation:
In this question, inverse of f(x) is equals to g(x). First, you must know how to find the inverse of f(x). In order to find the g(x), you must let f(x) = y and make x thd subject :
1.
Let y = (10x+9)/8
y = (10x+9)/8
8y = 10x + 9
8y - 9 = 10x
(8y-9)/10 = x
x = (8y-9)/10
g(x) = (8x-9)/10 (Remember to convert y back to x)
2.
Let y = x - 9
y = x - 9
y + 9 = x
x = y + 9
g(x) = x + 3
Next, by looking in no.1, the inverse of f(x) is wrong and in no.2, it shows the correct form of inverse. So only 2 is an inverse function

Answer:
The following shape is not a rectangle, but a square. I know this because the length and width are the same amount of square inch(feet, what ever the square counts for on your graph.) and rectangles width are typically longer than their length. However a square shares the same length and width,
Step-by-step explanation:
To determine how much you get per hour, divide 44 by 4, 88 by 8, and 132 by 12. Each time you get 11, so you get 11 dollars an hour.
If y = money earned and x = number of hours worked, then
y=11x
because the money you get is 11 times the amount of hours you work.
Hope this helps and I can provide further explanation if needed!
