Answer:
Not necessarily, but they could be.
Step-by-step explanation:
The only time two lines are parallel is if they have the exact same slope. Since both are positive here, that could be true. However, if they differ even the slightest bit, than no, they would not be parallel.

To determine the amount of water Sam drinks in an hour, divide the total amount drunk by the number of hours
Amount drank in an hour = total litres drunk / time
÷ 
× 
= 
= 2
litres
X=4 so

2x4=8
8+31 =39

Answer: Hello there!
we have the equation a(n) = (1/2)n - 1 for n ≥ 1
First we need the first five terms:
a(1) = (1/2)*1 - 1 = -1/2
a(2) = (1/2)*2 - 1 = 0
a(3) = (1/2)*3 - 1 = 1/2
a(4) = (1/2)*4 - 1 = 1
a(5) = (1/2)*5 - 1 = 3/2
then we can see that each term is 1/2 bigger than the previous one, then a recursive relation can be written as:
a(n) = a(n-1) + 1/2
where n ≥ 2, and a(1) = -1/2
