You can get this by switching the x and f(x) in the equation and then solve for f(x)
f(x) = 19/2x - 21 ---> now switch them
x = 19/2f(x) - 21 ---> now add 21 to both sides
x + 21 = 19/2f(x) ---> now multiply by 2/19 on both sides
(2x + 42)/19 = f(x) ---> ANSWER
Answer:
What are the choices?
Step-by-step explanation:
The answer would be 185 bc if you add all of them up that’s what u get
45 over 48 because 3 over 8 times 1 over 6 equals 3 over 48 and 48 take away 3 equals 45
