What does x equals x mean?
The "equals" means that you claim that whatever is on the left of the equal sign is the same as whatever is on the right of the equal sign. In this case, it is claimed that x is the same as x - a true claim.
Does the x and y coordinate have the same sign?
Not necessarily.
Do the x- and y- coordinates have the same sign?
Yes
How are math expressions and math equations the same?
They are the same except equations use the equal sign =
In which quadrants for the x-coordinates and the and y-coordinates have the same and sign?
The quadrants where the x-coordinates and y-coordinates have the same sign are Quadrant I and Quadrant III. In Quadrant I, both x and y are positive, while in Quadrant III, both x and y are negative.

Do x 5 and 5 x represent the same thing?
The answer depends on the sign (if any) between 5 and x : which we cannot see. If there is none, or if it is the sign for multiplication or addition then "yes". Otherwise, no.
What are the rules for points reflected over the x-axis?
The x value remains the same, but the y value changes sign
How do you subtract two integers with the same sign?
It is normal subtraction. if the tw numbers are x and y then the subtraction is x-y
Do X and y coordinates have same sign?
Sometimes they do, sometimes they don't.It depends upon which quadrant the point is in:In quadrant I they both have the same sign - positive;In quadrant II they have the different signs - x is negative whilst y is positive;In quadrant III they both have the same sign - negative;In quadrant IV they have the different signs - x is positive whilst y is negative;
In which quadrant(s) do the x- and y-coordinates have the same sign Check all that apply.?
The x- and y-coordinates have the same sign in the first and third quadrants. In the first quadrant, both x and y are positive, while in the third quadrant, both x and y are negative. Therefore, the correct quadrants are Quadrant I and Quadrant III.
When is true that absolute value of x plus y equals sum of their individual absolute values?
When 'x' and 'y' both have the same sign.
Does cos x equal cos negative x?
Yes. Cosine is adjacent side over hypothenuse. Adjacent side is the same sign when x is positive or negative.
