Answer:
Option (2)
Step-by-step explanation:
Given function is,
9y - 6 = 3x
y =
To find the inverse of the given function,
1). Substitute x in place of y and y in place of x.
x =
2). Now we have to solve this equation for the value of y.
9x = 3y + 6
3y = 9x - 6
y = (3x - 2)
Therefore, inverse of the given function is y = (3x - 2)
Option (2) will be the answer.
Try the last one; it doesn't mention anything foreign.

Janes weight = x
Twelve pounds less than twice janes weight is 270 pounds
12 less than 2x is 270
2x -12 = 270 (add 12 to each side)
2x = 270 + 12
2x = 282 (divide 2 from each side)
x = 282/2
x = 141
The answer is 141 pounds
