Answer:
I gotchu <333
Step-by-step explanation:
A: y = 0.50x + 5
(y= total amount of money)
(+5 = birthday money)
B: (25) = 0.50x+5
-5 -5
--------------------------------
20 = 0.50x gilberto needs to get 40 correct answers
(divided) / 0.50 /0.50
-------------------------------------
40 = x
C:
y= 0.50 (12) + 5 gilberto will recieve 11 dollars !
y = 6+ 5
y = 11

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
