Answer:
f^-1(x) = 3 - 5x, second option
Step-by-step explanation:
To determine the inverse simply interchange the variables and solve for y;
f(x) = 3 - x / 5 -> Interchange the variables
x = 3 - y/5 -> Multiply either side by 5
5x = 3 - y -> Subtract three from either side
- y = 5x - 3 -> Divide either side by - 1
y = - 5x + 3
Your solution is f^-1(x) = 3 - 5x
Answer:

Answer:
One. It is a = 7/3
Step-by-step explanation:
Let's simplify the equation 6a − 3a − 6 = −2 + 3 by combining like terms:
3a - 6 = 1
Adding 6 to both sides, we get:
3a = 7.
Dividing both sides by 3, we get
a = 7/3.
This equation has ONE solution, which is a = 7/3.
