Answer:
1000
Step-by-step explanation:
first you times 36 by 14 witch equals 54. Then do 54 x 20 = 1000 the 4 is gone because of the zero. So your answer should be 1000
The generic equation of the line is:

Where,
m: slope of the line
(T0, H0): ordered pair belonging to the line.
The slope of the line is:

Substituting values we have:

Rewriting:


Then, choosing an ordered pair we have:

Substituting values we have:

Rewriting the equation:

Then, for 8 hours we have:
Answer:
a linear equation to model the relationship between height H of the candle, and T time is:
the candle will be 12 inches after burning 8 hours
I think the answer could be A but I'm not so sure because at first Kayla has 6 boxes with x amount of books in the boxes with four left over so the equation would be 6x+4= number of books. So if she then replaces the now five boxes with x amount of books in them and adds four books to each of the five boxes you get 5x+4=number of books so it all equals out to the same number of books on both sides of the equal sign for 6x+4=5x+4
