Question 239776: For this problem write the equation that expresses the relationship among the variables, and then use the given data to solve for the variation constant
y is directly proportional to x, and y=38 when x=114
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
y = k*x
if y = 38 and x = 114, this becomes:
38 = k*114
k = 38/114
k = (1/3)
This is saying that y = (1/3) * x
38 = (1/3) * 114
38 = 38 confirming the value for k is good.
they are directly proportional which means that an increase in one yields an increase in the other by the stated proportion.
suppose y = 1
formula states that 1 = (1/3)*x which makes x = 3.
An increase of 1 in y will result in an increase of 3 in x.
2 = (1/3)*x makes x = 6
y increased by 1
x increased by 3
