Answer:
-6+x
Step-by-step explanation:
Let the number=n
x-n=6
-n=6-x
n=-6+x
The commutative property<span />
Xy=k, whenever the product of two variables is a constant it is called inverse variation. This is an inverse relationship, intuitively because, as the value of one variable increases, the other decreases and vice versa.
It is easy to spot as xy=k or y=k/x.
Answer: Choice B) 
Work Shown:

Note: secant is positive in quadrant Q4, when theta is between 3pi/2 radians and 2pi radians (270 degrees and 360 degrees). So that's why we don't consider the minus form of the plus minus.
