What is an equation with a variable in the denominator called?
A fraction.
How do you move a squared variable that is the denominator to the other side of the equation?
It's the same as if you have anything else in the denominator. You can multiply both sides by the squared variable. Example (using "^" for "power"): a = 1 / b^2 Multiply both sides by b^2: Step 1: a b^2 = b^2 / b^2 Step 2: a b^2 = 1
What is an expression that may include monomials binomials and more and That has no limit to the number of terms. However the variable if applicable CANNOT appear in the denominator of a fraction.?
A polynomial.
What are the values of the variable that must be excluded from the domain x plus 8 over x 4?
Any value of x which causes the denominator to equal zero. It's kind of vague, but if you mean the denominator to be (x raised to the 4th power), then x=0 must be excluded. If you mean (x + 4) then x=-4 will make the denominator equal zero, and if you mean (x-4) then x=4 will make it zero.
How do you get the variable by its self if its in a fraction?
if you have a variable in a fraction and want it by itself you have to rearrange the equation e.g. 2x/1=1 to get the variable by itself you first need to get rid of the fraction SO... you multiply both sides by the denominator (in this case it's 1) so you end up with 2x=1 to get the variable alone you then need to get rid of the coefficient, which in this case is 2. To get rid of this coefficient you need to divide both sides by two (because the variable is multiplied by 2) so then you end up with 2x/2=1/2 We can then simplify to x=1/2.
Which term describe a fraction that has a variable or variable expression in its numerator its denominator or both?
It is a variable fraction.
What is a nonpermissable replacement in rational expressions?
Replacing the variable in the denominator by a root of the denominator.
Explain how to find restrictions on the variable in a rational equation?
Substitute the variable in the denominator for a value that will make the denominator have a value of 0 or an imaginary number
What is an equation with a variable in the denominator called?
A fraction.
What can a monomial fraction NOT have in its denominator?
Variable exponents.
What term describes a fraction that has a variable or variable expression in its numerator or it's denominator?
It is a variable fraction. But it need not be algebraic.
When a variable appears in the denominator of one or more term is called?
It is called a variable fraction.
Which term describes a fraction that has a variable or variable expression in its numerator its denominator or both?

How do you multiply a fraction containing a variable by a variable?
in reducing fractions deviden the numerator by denominator
How do I remove a variable out of the denominator when you are working with a rational equation?
You multiply both sides of the equation by the denominator.
How do you find the excluded value when there isn't a variable in the denominator?
There could be a variable in the numerator which is not defined. For example, [tan(x)]/3 has no variable in the denominator but the expression is not defined for x = pi/2, for example (90 deg).
Which term describes a fraction that has a variable or variable expression in its numerator it's denominator or both?
It is a variable fraction, NOT an algebraic fraction.
