=2/sqrt(3) .... now rationalize
=2sqrt(3)/3
State tax is computed by first subtracting the amount of exemptions
(5*$1000=$5000) from annual income and then multiplying it by the state
tax.
($18150-$5000)*5%= $657.50
5(∛x) + 9(∛x)
= ∛x (5 + 9)
= 14∛x
Answer is the third option

Answer:
129-14 is 115 than minus 6 than add 12
Step-by-step explanation:
Answer:
![f[2-f^{-1}(x)]=x](https://tex.z-dn.net/?f=f%5B2-f%5E%7B-1%7D%28x%29%5D%3Dx)
Step-by-step explanation:
Given function is,
f(x) = 
Equation form of the function will be,
y =
Interchange x and y,
Solve for y,
y = 2x + 1
Therefore, inverse of the function 'f' will be,
Now ![[2-f^{-1}(x)]](https://tex.z-dn.net/?f=%5B2-f%5E%7B-1%7D%28x%29%5D)
= 2 - [2x + 1]
= -2x + 1
Value of ![f[2-f^{-1}(x)]](https://tex.z-dn.net/?f=f%5B2-f%5E%7B-1%7D%28x%29%5D)
= f(2x + 1)
From the given function,
f(2x + 1) = 
= x
Therefore, value of
