In an integer proegramming problem if it is desired to have variable X be exactly twice the value of variable Y the constraint would be written how?
AmazinglyMoni
You could write it as X = 2Y, but in that case, you might as well drop one of the variables from the problem and substitute X = 2Y or Y = X/2 throughout.

Why you have to declare variable first in turbo c?
All variables (and constants) must be declared before they can be used. This is so the compiler knows exactly how much memory to allocate to the variable, as the declaration tells the compiler exactly what the variable's type is.
A function is a rule that assigns each value of the independent variable to exactly value of the dependent variable?
false
What does independent variable mean in math?
An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.
When can we say that a relation is not a function?
When it doesn't fulfill the requirements of a function. A function must have EXACTLY ONE value of one of the variables (the "dependent variable") for every value of the other variable or variables (the "independent variable").
When an experiment shows that's one variable makes another variable change and no other variables have any effect the experiment shows?
The experiment shows exactly what your title says!
What is it called exactly what you are going to measure?
A dependent variable.

A function is a rule that assigns each value of the variable to exactly one value of the dependent variable?
I found two answers for this question. A function is a rule that assigns to each value of one variable (called the independent variable) exactly one value of another variable (called the dependent variable.) A function is a rule that assigns to each input value a unique output value.

false
Specifying exactly what is to be measured in assigning a value to a variable is called what?
operationalization
What rule assigns each value of the independent variable to exactly one value of the dependent variable?
It is any invertible function.

An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.
When solving by the substitution method what happens when one variable cancels out?
That's exactly the purpose of the substitution method ... to get an equation with one less variable. When you have it, you solve it for the variable that's left.
What process involves deciding exactly what is to be measured when assigning value to a variable?
operationalization
Why is it important to test one variable at a time in an experiment?
If you change more than one variable at a time, you will not be able to tell which variable is responsible for what change. Scientists need to know exactly which variable caused the observed experimental results.
When can we say that a function is a relation?
When it doesn't fulfill the requirements of a function. A function must have EXACTLY ONE value of one of the variables (the "dependent variable") for every value of the other variable or variables (the "independent variable").
