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.
the value of x is 3
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.
The value of 'x' is 50.
The answer depends on the value of x, which is not given.
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.
It depends on the relationship between x and y.
The domain is the x value
x can have any value in the domain.
