Answer:

\frac{3(6)-1}{2(6)+1}\text{ or }\frac{18-1}{12+1}\text{ or }\frac{17}{13}

Step-by-step explanation:

Given functions,

r(x) = 3x -1------(1)

s(x) = 2x + 1-----(2)

\because \frac{r}{s}(6)=\frac{r(x)}{s(x)}

From equation (1) and (2),

\frac{r}{s}(x)=\frac{3x-1}{2x+1}

Put x = 6,

\frac{r}{s}(6) = \frac{3(6)-1}{2(6)+1}=\frac{18-1}{12+1}=\frac{17}{13}
