Help please! (easy question)

Answer 1

y = 7 - 2x

Explanation:

Your starting point is 7, so that will be by itself.

y = 7

If your candle burns 2 inches per hour, and x is the number of hours the candle burns you would want to combine the two.

You combine the two because multiplying 2 by the number of hours the candle burns gives you the total inches the candle loses. So:

2x

Now you just combine the two statements

y = 7 - 2x

Answer 2

y = 7 - 2x

Explanation:

Note that:

y = height of the candle

x = hours

The candle starts at 7 inches, and can only grow smaller as it is burnt. It also burns in a constant 2 inches per hour. Note that it is "2 inches per hour, or 2 * h (h = hour). It is also burning, or taking away, from the original, or 7. Therefore, y = 7 - 2x is your answer.
