Question

If (x)=3x-1 and s(x)=2x+1, which expression is equivalent to r over s (6) ?

Answer 1

Answer:

$\frac{3(6)-1}{2(6)+1}$

Step-by-step explanation:

we have

$r(x)=3x-1$

$s(x)=2x+1$

so

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

substitute the value of $x=6$ in the expression

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