Proportional Relationships
A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if:
y=kx
for some constant k , called the constant of proportionality .
(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .")
This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.
The graph of the proportional relationship equation is a straight line through the origin.
Answer:
Option D : t = 5s + s/2 is the correct answer.
Step-by-step explanation:
Given that:
t = Combined weight of water and food
s = weight of the snail
Water drank by snail = 5s
Food ate by snail = s/2
Combined weight = Weight of water + Food
t = 5s + s/2
Hence,
Option D : t = 5s + s/2 is the correct answer.
