= 
÷ 
Cancel common factors on numerator/ denominator of both fractions
= 
÷ 
Change ÷ to × and turn second fraction upside down
= × 
Cancel the common factor 4x - 1 on numerator/ denominator, leaving
Answer:
Step-by-step explanation:
To obtain the inverse of f(x)
let y = f(x) and rearrange making x the subject, that is
y = 2x - 1 ( add 1 to both sides )
y + 1 = 2x ( divide both sides by 2 )
= x
Change y back into terms of x with x = 
(x) , thus
(x) = 
Evaluate g(3) and substitute the value obtained into (x)
g(3) = 3² + 1 = 9 + 1 = 10, then
(10) = 
=

x + xy + 2y + xy Distributive property
x + xy + xy + 2y Commutative property of addition
[a + b = b + a]
x + (xy + xy) + 2y Associative property of addition
[(a + b) + c = a + (b + c)]
x + 2xy + 2y Combine like terms

Answer: 5742
================================================
Work Shown:
x = number of yes votes
(number who said yes)/(number who said no) = 4/5
x/3190 = 4/5
5x = 3190*4 .... cross multiply
5x = 12760
x = 12760/5 ... divide both sides by 5
x = 2552
There were 2552 people who voted yes
The total number of votes is 2552+3190 = 5742
