is dependent variable x or y?
is domain x or y?

anonymous · Answer

Umm, not sure\: Didn't understand this question.

anonymous · Answer

do you know what independent variable means?
do you know what dependent variable means?
do you know what domain and range are? do you know which is which?

anonymous · Answer

Independed = A variable which the variation does not depend on it.
Depended variable = opposite of Indepedent which the variable does depend on the variation.
Domain and range I dont know.

anonymous · Answer

Independent* Dependent*

anonymous · Answer

independent variable is what you change
dependent variable is what changes based on what you change

anonymous · Answer

Ahhh.

anonymous · Answer

domain is the values of x you use
range is the values of y that can come out

anonymous · Answer

Alright, so how could I figure this out\:

anonymous · Answer

so if they change the amount they charge nothing happens to the number of cars that come, so what does that tell you about the independent and dependent variables?

anonymous · Answer

I have no idea. Gahh

anonymous · Answer

how about this. Which one depends on what the other one is?

anonymous · Answer

Dependent Variable.

anonymous · Answer

the amount of money they make or the number of cars they wash?

anonymous · Answer

Amount of money they make.

anonymous · Answer

yes, so that is the dependent variable

anonymous · Answer

Alright so Independent would be the number of cars they wash.

anonymous · Answer

and therefore the other one is the independent variable

anonymous · Answer

So it would be B?

anonymous · Answer

Well, B or C.

anonymous · Answer

B or D I mean

anonymous · Answer

now you look at domain and range

anonymous · Answer

the independent variable always goes on the x-axis, the dependent variable goes on the y-axis

anonymous · Answer

How would I find that out?
