Answer:
Step-by-step explanation:
Given:
The table is given as:
x 0 4 7 8
y 0 24 42 48
The relationship between 'x' and 'y' is a proportional relationship.
A proportional relationship is one in which one variable varies directly with the other by a factor of 'k' also known as constant of proportionality and
A proportional relationship is given as:
Now, we plug in 'x' and 'y' values and find the value of 'k'.
Let
Therefore, the constant of proportionality is 6. Hence the complete equation is given as:
Answer:
In the given expression x:6 :: 3:9 , x = 2
Step-by-step explanation:
Here, the given expression is:
x:6 :: 3:9
or, x : 6 = 3 :9
So, by the RATIO OF PROPORTIONALITY:
or, x = 2
Hence, in the given expression x:6 :: 3:9 , x = 2
