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.
The answer is 5:2 ration, it's already fully simplified
Answer:
-1/3
Step-by-step explanation:
To find the slope, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 9-10)/(10-7)
= -1/3
Answer:
-12x+29
Step-by-step explanation:
= -2(x+3) – 5(2x – 7)
= -2(x)+(-2)(3)-5(2x)-5(-7)
= -2x-6-10x+35
= -2x-10x-6+35
= -12x+29
It’s A or D but I have a strong feelin it’s A
