Question

Which relationships have the same constant of proportionality between yyy and xxx as the equation 3y=27x3y=27x3, y, equals, 27, x?

Answer 1

The answers are A B and C

Explanation:

I just got it right

Answer 2

See Explanation

Explanation:

The options are not given; however, the solution is as follows;

`3y = 27x`

Required

Determine relationships with the same constant of proportionality (k)

`3y = 27x`

Divide both sides by 3

`(3y)/(3) = (27x)/(3)`

`y = (27x)/(3)`

`y = 9x`

The relationship between y, x and k is:

`y = kx`

Comparing
`y = kx` with
`y = 9x`; then

`k = 9`

Hence, any of the options with k=9 answers the question.

Take for instance:

`2y = 18x`

Dividing both sides by 2 gives

`y = 9x` and hence;
`k = 9`
