Question

Choose the equation that matches a relationship where the input (x) is doubled and 5 is added to the product in order to get the output (y).

(A)
2y + 5 = x
(B)
2x + 5 = y
(C)
2(y + 5) = x
(D)
2(x + 5) = y

Answer 1

First of all, we start with the input
`x`

Then we double it:
`2x`

Then we add 5 to this result:
`2x+5`

And this is the output:
`y=2x+5`
