Answer:
The correct answer is
Step-by-step explanation:
Method 1
We want to simplify,
The double negatives becomes positive,
We now add the whole number parts and the fractions separately
This will give us,
The least common denominator for the fractional parts is 9.
Method 2
We want to simplify,
The double negatives becomes positive,
We first convert the mixed numbers to improper fractions to obtain,
We carry out the multiplication in the numerator to get,
We add in the numerator to get,
The least common denominator is .
We convert back to mixed numbers to get,
Translate it
remember that
translates to 
so we can say it equals y
so
translates to 
we want to find the values of x that make it undefined
well, we know that
must be greater than 0
so we do
it is defined for
x-4>0
add 4
x>4
it is defined for all values such that x>4
