Question

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

Answer 1

The correct options for this question are missing: Here are the options:

1) 3(6) - 1/ 2(6) + 1

2) (6) / 2(6) + 1

3) 36 - 1/26+1

4) (6) - 1/(6) + 1

Answer:

r(x) = 3x - 1

s(x) = 2x + 1

The ratio for r/s(x) will be equal to 3x - 1/2x + 1

and for this x will be equal to 6

now we will put in the value of x in the equation

3(6) - 1/ 2(6) + 1

So for this question the answer is the first option

3(6) - 1/ 2(6) + 1

Answer 2

r(6)/s(6) = 3(6) -1

--------------

2(6) +1

Explanation:

r(x) = 3x-1

Let x=6

r(6) = 3(6) -1

s(x) = 2x+1

Let x=6

s(6) = 2(6) +1

r(6)/s(6) = 3(6) -1

--------------

2(6) +1
