Suppose that the height (in centimeters) of a candle is a linear function of
the amount of time (in hours) it has been burning.
Let x be the amount of time in hours
Let y be the heoght of a candle in centimeters
The two points are then as (9,24.5) and (23,17.5).
Now plug in x=21, we get
Thus the height of the candle after 21 hours is 18.5 centimeters.
Answer:
3n^2 - 5n - 28
Step-by-step explanation:
(n - 4)(3n + 7)
3n^2 + 7n - 12n - 28
3n^2 - 5n - 28
hope this hepls!!!

Answer:</h3>
x=2
<h3>
Solution:</h3>
- In order to isolate x, we should first of all take the square root of both sides.
- If we take the square root of the left-hand side, we will get
- How about the right-hand side? Well, we should take the square root of the numerator (9) and the denominator (4)
- So we have
- Move -1/2 to the right:
- x=2
Hope it helps.
