What is a Varriable Expression?
Any expression that contains one or more variable, such as x; x+2; x+y; x2, etc. Depending on the values of the variables, the expression can also have different values.
What is the value of the rational expression x plus 4 divided by 4 minus x?
8
If an original expression is defined for all values of x you do not need to specify the absolute value in the simplified expression.?
The assertion is not true. Consider the function f(x) =|x - 3|, which is the distance of x from the point 3. The function is defined for all x but the absolute value is required.
How is an equation different from an algerbraic expression?
X2 Is an algebraic expression. X2 = 4 Is an equation that can be solved for X. The variable, X, in this case, has two values. In the expression any value can be substituted for X.
If an original expression is defined for all values of x you do not need to specify the absolute value in the simplified expression T F?
first, you have to divide. Then, you have to add X to what you got when you divided. After that, you shove it up your butt and cry
Which expression has the same value as tan(-x) for all values for x?
tan(-x) = -tan(x)

What is the square root of 6X-5?
11
What values of x make the expression 5-xx(x-2) undefined?
The expression 5 - x(x)(x-2) will be undefined when any factor in the expression results in division by zero. This means that x cannot be equal to 0, x, or 2 for the expression to be defined. Therefore, the values of x that make the expression undefined are x = 0, x = 1, and x = 2.
Are the any values for x for which each rational expression is undefined xoverx plus 8?
The expression X/(X+8) is undefined at X=-8, because that would be division by zero.
What values of x is expression meaningless 4x-26x-8?
-22x-8
What is yx50000?
It is an algebraic expression whose value depends on the values of y and x.
How do you evaluate a expression?
Replace all the variables in the expression by their numerical values and calculate the result.
