Answer:
y = 7 - 2x
Step-by-step 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.
~
You can isolate y on both sides, getting:
2x-17=y and x-10=y
Then, make the two y equal each other, and solve the equation
2x-17=x-10
The answer would be x=7.
then, plut in the amount into one of the equations:
x-y=10
7-y=10
y=-3
T
Therefore, the answer is x=7 and y = -3, or (7,-3)
