Does order matter in subtraction?
yes
What is the difference between a constant and coefficient term?
A constant is always the same number, no matter what formula or equation it is used in (this is different from using the same symbol for several constants, in which case it might be interpreted incorrectly as the wrong constant is used). Some exmaples are pi the circular constant, e the natural number constant and G the gravitational constant. A coefficient is the number multiplying a variable, e.g. in 5x2 and 9y, 5 and 9 are the coefficients of the x2 and y terms.
How is subtracting fractions different from adding fractions?
In subtraction you take away rather than add. Also, addition is commutative, subtraction is not so the order of the numbers does matter for subtraction.
What are the independent variables of a function?
An independent variable of a function is the variable that you cannot change by changing the other. Changes to it are not caused by the equation. If you want to graph how the money you invest in a bank account against the time that the money has been in the account, time is the independent variable. This is because the time will change at a constant rate, no matter how much or how often the money collects interest. If you change the equation, the money earned will change, but the time will not.
How do you know when a equation has an infinte number of solutions?
-- A single equation with more than one variable in it has infinitely many solutions. -- An equation where the variable drops out has infinitely many solutions. Like for example x2 + 4x -3 = 0.5 (2x2 + 8x - 6) As mean and ugly as that thing appears at first, you only have to massage it around for a few seconds to get -3 = -3 and that's true no matter what 'x' is. So any value for 'x' is a solution to the equation, which means there are an infinite number of them.
When subtracting an algebraic equation which comes first a variable or the constant?
It does not matter.
What is the difference between a constant and a coefficient?
In a linear equation given as y = mx + c, the c represents a constant. This is because the x- and y- variables don't directly influence it, and it remains exactly what it is - constant - no matter what.The m is the coefficient - the value which provides scale. It also remains constant, but it is coupled to the variable of this equation, x.In the quadratic equation y = ax2+ bx + c, the 'c' here is a constant, and both 'a' and 'b' are coefficients.Both 'a' and 'b' are attached to the variable x, so both are considered coefficients. This rule holds true for all orders of polynomials.(Important note: The letter 'c' is not always used to represent the constant value in an equation, so watch out - so long as it isn't influenced by the variable of the equation, it's the constant.)
With the substitution method which variable should you solve for first?
It often doesn't matter which one you solve for first. But if you can easily solve one of the equations for one of the variables, that's the one you should solve for.

What doese a coefficient tell you?
In chemistry, a coefficient in front of a chemical formula tells you how many moles you have. When balancing a chemical equation, the law of conservation of matter must be upheld. To do this, you add coefficients as needed, and these coefficients represent mole ratios of either reactants or products.

What is the number to the left to a chemical formula?
Balancing a chemical equation can often require a whole-number coefficient placed in front of a chemical formula. This upholds the Law of Conservation of Matter, which says that matter cannot be created or destroyed. These coefficients must be in the lowest possible ratio.

What does it mean when a differential equation is linear?
It means that the dependent variable and all its derivatives are multiplied by constants only, not by themselves nor by functions containing the independent variable.. For example, (dy/dx) + xy = 0 is non-linear but (dy/dx) + y = (x^2)coswx is linear. (Note that it doesnt matter how the function of the independent variable is)
Which phase of matter a variable volume?
Gas.
