The equation y = 3.25x can be used to determine the cost of purchasing x cans of chili. what is the constant of proportionality for this relationship?

3.25

Step-by-step explanation:

We are given an equation and we are asked to find the constant of proportionality.

Since we know that directly proportional equations are in form of , where k is proportionality constant.

Upon comparing both equations we can see that value of k is 3.25 for our given equation. Therefore, constant of proportionality for our given equation will be 3.25.

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
