What is the value of X?

Absolute value of -x is x.

In expressions such as "x-y", both "x" and "y" can have any value. The value of "x-y" will depend on what the value of "x" and the value of "y" are.

If the reflection is over the x value, the x-value does not change.

zero. The absolute value of a number is just the positive version of that number, so the absolute value of x is x, and x minus x is zero.

That depends what the value of x is.

If an expression is true "for no value" of x, it means that there is no value you can substitute for x to make it true. For example, x=x+1 is true for no value of x, because x is always strictly less than x+1.

That completely depends on the value of 'x'. Whenever 'x ' changes, the value of (2 + x) instantly changes.

It depents from the value of x. If x>0 then, |x|=x If x<0 then, |x|=-x

The domain is the x value

y is a function of x if for each value of x (in the domain) there is a value of y, and for each value of y (in the range) there is at most one value of x.

That is how the absolute value is defined. For x < 0 the value of x is negative (by definition). Therefore, the value of negative x is positive (negative of a negative). So abs(x) = -x when x < 0

If a number is not less than zero then that is its absolute value. If a number is less than zero, its negative is its absolute value. So, if |x| denotes the absolute value of x, then |x| = -x for x<0 [since if x<0 then -x>0] and |x| = x for x>= 0

The value of 'x' is 50.

The absolute value of a number is how many spaces the number is away from 0. So if the number was 32, the absolute value would be 32. And if the number was -54, then the absolute value would be 54. ========== The definition of "absolute value" for a number x (written as |x| ) is: |x| = x for x >0 |x| = 0 for x=0 |x| = -x for x<0

The absolute value of the opposite of x is x. The absolute value is the number's distance from zero on a number line. Distance can not be negative, so basically, to find the absolute value of a number you just need to make it positive. The opposite of x is -x. |-x|=x - you make the x positive Of course, if x, to begin with, represents a negative (less than zero) number than the absolute value would be -x. For example if x=-3, the opposite value of x would be 3 and the absolute value of x would also be 3 which happens to be -x.

x can have any value in the domain.

The value of x is directly proportional to to the value of y.hence when the value of x increases the value of y decrteses and vice verse

If you mean: 5x = 10 then the value of x is 2

If you mean: x+y = 30 and the value of y is 15 then the value of x is also 15

Do you mean "what is the value of x when 3x - 2x = 15?" in that case, the value of x is 15

what is the absolute value of -4

Suppose x is a rational number -x is the [additive] opposite of x. If x < 0 then -x > 0 so that the absolute value is -x (if x is negative then -x is positive). if x >= 0 then the absolute value is x.

The absolute value of a positive number is the same number - in this case, 1.5. The absolute value of a negative number is the number, without the sign. Note that the absolute value of an expression like (-x) is not necessarily (x); rather, you have to separately consider the case that x is positive, or that x is negative. For example, the absolute value of x is x (if x is positive), or (-x) (if x is negative).

There is no possible value of x that will satisfy the given equation. There is no possible value of x that will satisfy the given equation. There is no possible value of x that will satisfy the given equation. There is no possible value of x that will satisfy the given equation.
