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

Answer 1

`(17)/(13)`

Explanation:

Given that,

r(x) = 3x - 1 and s(x) = 2x + 1

We need to find an expression equivalent to
`(r)/(s)(6)`.

We know that,

`(r)/(s)(6)=(r(6))/(s(6))`

Put x = 6 in the above expression

`=(3(6)-1)/(2(6)+1)\\\\=(18-1)/(12+1)\\\\=(17)/(13)`

So, the equivalent expression is equal to
`(17)/(13)`.
