What equation is true for some values of its variable and is not true for others?

No equation can have that property.
It cannot be an equation if it is not true. If necessary, the domain must be amended. An equation can have different forms over different parts of its domain.

What is the difference between identity and a conditional equation?
Identity: An equation satisfied by every number that is a meaningful replacement for the variable. Example: 3(X+1)=3X+3Conditional Equation: An equation that is satisfied by some number but not others, such as 2X=4
What makes an equation a quadratic function?
Basically the fact that some variable is squared - or that one variable is multiplied with another variable.
Which table of values could be generated by the equation 10x 5y15?
The equation isn't quite clear - some symbols get lost in the questions. In any case, you can solve the equation for "y", then replace some values of "x" and use the equation to calculate the corresponding values for "y".
What is the difference between a function and an equation?
A function describes a relation between several variables. For example the function f(x)=x2 describes a mapping from the variable x to a value that is the square of x. That is, for every real number we put as x, we will get a value for f(x). A function is defined for some domain and gets values from some range. An equation takes two terms and says they are equal. Usually both terms are functions of the same variable(s). For example, to build the equation x2 = x+2, we will use f(x) = x2, g(x) = x+2 and say that f(x)=g(x). Solving an equation means finding the set of values of the equation's variables which satisfy the equation. This set of values has to be part of the domains of the functions in both terms of the equation.
What is a literal equation?
Literal Equations are what are commonly referred to as formulas, or formulae. They are recipes for finding the numeric value of a variable, assigned a "letter" name (hence "literal") that typically stands for some sort of real-world quantity, such as Volume, Temperature, Pressure, amount of interest an investment earned, and so on.This variable has an established relationship to other quantities that are also assigned "letter" names in the recipe (the equation),that gives the relationship between (or among) the quantities. The deal is, if we know the values for all of the variables in the recipe except one, then we can plug those values into the recipe and solve for the one variable whose value we don't know.
Why would you want to solve a literal equation for a variable when you could simply plug in known values and then solve the resulting linear equation?
if you solve by plugging in the known values ahead of time you won't have a general formula for the variable in the literal equation. Therefor if the known values change, you would have to start all over again, making each problem more individualized. Once the literal equation is solved for some variable, if the known values change all you have to do is plug in those new numbers to your literal equation, and out pops your answer
What is x values?
They comprise a set of values for some variable x.
Which property justifies 3x-6 equals 17?
There is no property that justifies it. The equation is true for some values of x, not for others.
When a variable appears in the denominator of one or more terms of an equation?
It is a variable fraction. The exact nature will depend on the form in which the variable appears:as part of an algebraic, trigonometric, etc function. In some cases the fraction will have a name, in others it will not.
How do you create an equation for a parabola?
An equation for a parabola always has some type of irregular variable, usually a squared variable or higher.
What is the difference between identity and a conditional equation?
Identity: An equation satisfied by every number that is a meaningful replacement for the variable. Example: 3(X+1)=3X+3Conditional Equation: An equation that is satisfied by some number but not others, such as 2X=4
What can be useful when finding the value of a variable?
A value of some function of the variable at some point and an equation which links the two.
What is difference between parameter and arbitrary constant?
A parameter is a variable which takes different values and, as it does, it affects the values of some other variable or variables.
Which table of values could be generated by the equation 10x 5y15?
The equation isn't quite clear - some symbols get lost in the questions. In any case, you can solve the equation for "y", then replace some values of "x" and use the equation to calculate the corresponding values for "y".
What makes an equation a quadratic function?
Basically the fact that some variable is squared - or that one variable is multiplied with another variable.
How do you solve a variable?
You cannot solve a variable. You can solve an equation to find the value (or range of values) of a variable. How you do that depends on the nature of the equation that you have. Linear and quadratic equations are relatively simple, as are many trigonometric and exponential equations. But some cannot be solved in such a way and a numerical solution is required. Here you would make a guess and then improve on that guess and then improve on that until you were satisfied that you were close enough to the real answer.
Why is yoga an independent variable?
Yoga can be an independent variable in some experiments and a dependent variable in others.
