Question

If r(x) = 3x – 1 and s(x) = 2x + 1, which expression is equivalent to mc015-1.jpg?

Answer 1

3(6)-1/2(6)+1 is the correct answer

Answer 2

we have

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

we know that

the ratio $\frac{r}{s}(x)$ is equal to

$\frac{3x-1}{2x+1}$

for $x=6$

substitute the value of x in the equation

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

therefore

the answer is the first option

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