The independent variable is the one you use or have first. 

Eg.      Y=x+4

Normally you have an  x value then you plug it into the equation to get the y value.

So the x is the first value. It is independant. The y is the second value it depends on what x is.

This can be extended to normal and statistical meaning to.

Whether or not you are wearing wet weather gear is dependent on whether or not it is raining.

It does not work the other way around. Putting wet wrather geat on will not MAKE IT rain. So the rain is the independent variable.

Look at this.

No it isn't, it is Mathsfordays !

99.9= 999/10

I'd like to see the equation for this one too.

Physics always fascinates me. :)

I found this page but I am still confused.

You make great use of this reference site Solveit, hopefully some of the students here will bookmark this site you constantly refer to so they can get their questions ansered immediately sometimes. :)

if an amount of money is invested at an annual interest rate of 6%,it doubles every 12 years.if alejandra invests $500, how llong will it take her investment to exceed $2000 (assuming she doesn't contribute any additional funds)?

WEll it doubles every 12 years so    (assuming the initial statement is correct)

start                       $500

beginning of 12th year    $1000

beginnnig of 24th year    $2000

So 24 years.
