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.
Not necessarily.
Yes
They are the same except equations use the equal 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.

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.
The x value remains the same, but the y value changes sign
It is normal subtraction. if the tw numbers are x and y then the subtraction is x-y
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;
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 'x' and 'y' both have the same sign.
Yes. Cosine is adjacent side over hypothenuse. Adjacent side is the same sign when x is positive or negative.
