f r(x) = 3x – 1 and s(x) = 2x + 1, which expression is equivalent to ?

Answer: The first option.
Step-by-step explanation:
You have the following functions:
[tex]r(x)=3x-1\\s(x)=2x+1[/tex]
You have that [tex](\frac{r}{2})[/tex] indicates the following:
[tex](\frac{r}{s})=\frac{3x-1}{2x+1}[/tex]
Now, you must substitute x=6, then you obtain:
[tex](\frac{r}{s})(6)=\frac{3(6)-1}{2(6)+1}[/tex]
Therefore the answer is the first option.
Answer:
Choice A is correct answer.
Step-by-step explanation:
We have given two functions.
r(x) = 3x – 1 and s(x) = 2x + 1
We have to find the quotient of the given two functions.
(r/s)(x) = ? and (r/s)(6) = ?
The formula to find the quotient is:
(r/s)(x) = r(x) / s(x)
Putting given values in above formula, we have
(r/s)(x) = 3x-1 / 2x-1
Putting x 6 in above equation, we have
(r/s)(6) = 3(6)-1 / 2(6)-1 which is the answer.
