if x varies directly at I and x=6 when I=2.what is the relationship between x and i. what is the value of I when x = 15

The equation will be x=3l and the value of l is 5 when x=15

Step-by-step explanation:

Proportion is defined as the change in one quantity cause change in other quantity.

Writing x varies directly at l

x∝l

Removing the proportionality symbol introduces a constant of proportionality

x=6 when I=2, Putting values

The equation will become

Now to find the value of l when x=15, putting x=15 in equation

Hence,

The equation will be x=3l and the value of l is 5 when x=15

answer: .64
