Answer: I don’t honestly know. I just need points
Explanation:
Answer:
The option 'b' is true.
Step-by-step explanation:
Given the expression

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

Replace x with y

solve for y

Thus,

Therefore, option b is true.
The answer to this is a=3.6
Answer:
y= -6+2/3x
Step-by-step explanation:
2x-3y=18
Minus the 2x from both sides
-3y=18-2x
Then divide both sides by -1
-3y÷-1=18÷-1 -2x÷-1
Lastly divide both sides by 3
3y÷3= -18÷3+2x÷3
