Lola's hair today is 24" long. It grows 1.5" per month. She is a pretty tall girl for her age, about 60" right now! Her brother has long hair too. His hair is about 12" long. What does the y stand for?

Sagot :

If I'm correct, you're asking which variable is the dependent variable y from the question

Answer and explanation:

The equation can be modelled:

y= 1.5x

Where y is the current length of the hair

x is the number of months of hair growth

We can see from the equation therefore that y is a dependent variable that depends on x the independent variable, the number of months, to get a value. In other words given that her hair grows at a constant rate of 1.5 inches per month, her hair length is based on number of months x of growth in inches of hair.
