You can simply put the equation as 9x = 36 and divide by 9, then x = 4
<em><u>Question:</u></em>

the answer to this question (-2,3)
<span>You can get those ordered pairs subtracting 9-0.5, then that result minus 0.5 because from the rate the candle reduces its height 0.5inches per each hour.Part B: Is this relation a function? Yes, because each value of x has a single result or output in “y” (image)Part C: Yes, only difference is the time, the candle reduces its height 0.45 inches per each hour, examples of ordered pairs: (0,9) (1,8.55) (2,8.1)</span>
Do you mind typing the equation it looks incomplete.
