you must first have a complete equation (something = something else)
then using valid mathematical rules simplify the equation and begin to isolate the variable to one side giving the answer on the other side
whoever asks this question is gay! math is for geeks! LOOSER! B-)

Difference between nominal and real variable?
A nominal variable is a variable measured in current dollars (the value of the dollar for the specific period discussed), and a real variable is a variable measured in constant dollars (the value of the dollar for the base period). That is, a real variable adjusts for the effects of inflation.
What rule assigns each value of the independent variable to exactly one value of the dependent variable?
It is any invertible function.
What does a bar graph display?
Each bar displays the value of one variable for one value of a second variable. The second may be a qualitative variable or a quantitative one.
A variable whose value is a numerical outcome of a random phenomenon is called?
random variable.
Is the expected value of a discrete random variable equal to the mean of the random variable?
yes?
Why do you isolate the variable on one side the the equation when solving a linear equation?
Isolating a single variable in terms of the rest of the equation provides a solution to that variable. That is, if you know the equation that equals the variable, then you can figure out its value.
How you can modify an integer variable value in a function?
with an assignment: variable = value variable += value variable /= -3; ...
What is a depened variable?
The key word here is 𝘥𝘦𝘱𝘦𝘯𝘥𝘦𝘯𝘵. This means that the variable's value depends upon something else. For example, to figure out Y, you need to multiply 4 times X and then add 3. Whatever value you put for X determines what Y's value will be. So Y depends upon the value of X . That makes Y a dependent variable.
Variable is the value whose value depends upon the value of the independent variable?
The dependent variable is the variable that depends on the independent variable.
How do I plug in a variable?
You cannot plug in a variable, what you do is plug in the value for a variable. If you know the value of the variable in an equation (or formula), the process of replacing that variable whenever it appears in the equation by its value is called plugging in the value for the variable.
What is a variable expression that has a decreasing value as the value of the variable increases?
what is a variable expression that has a decreasing value as the value of thevariable increases?
What is independent a dependent variables?
The independent variable is the variable that is altered by the scientist, and the dependent variable's value is dependent on the value of the independent variable.
How do you quantify a variable?
explain what it means to quantify a variable I think to quantify a variable is to be able to place a value/figure to something. eg: smoking 1 cigarette a day can reduce your life expectancy by say... 7mins. Any other ideas... someone?
What are the ways to solve a system of linear equations in two variables?
the substitution method in which you take each variable and you find out the value and then plug it into the original equation.the adding and subtracting method in which you subtract\add equations to take out a variable and you can figure out what the other variable is. then you also substitute that into that into the original variable
What is y in math?
In math y or any other letter is known as a variable. Because to figure out the problem you must find out the value of y.
A represents an unknown or changeable value?
a variable
What is the variable that depends on the value of the other variable?
dependent variable
