Step-by-step explanation:
The ratio and proportion is the mathematical concept that can explain the correlation between the size of a dog and the amount of food it eats. For example dogs weighing 3 to 7 kg should consume 67 to 112 grams of food per day, that is, the amount of food must be proportional to the weight of the dog.
The ratio and proportion are interconnected concepts that allow the understanding of comparison between quantities.
Answer:
Step-by-step explanation:
Given:
Family of 2
Cost, C1 = $25
Family of 6
Cost, C2 = $65
Given that 2 points are given above as the following in coordinate form:
A(2,25) and B(6,65)
Rate of change is given as = (y2 - y1)/(x2 - x1)
= (65 - 25)/(6-2)
= 40/4
Therefore,
(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1)
(y - 25)/(65 - 25) = (x - 2)/(6 - 2)
(y - 25)/40 = (x - 2)/4
(y - 25) = 40/4 × (x - 2)
(y - 25) = 10 × (x - 2)
Expanding,
y - 25 = 10x - 20
y = 10x - 20 + 25
y = 10x + 5
