I need help on. this one pliss

How do the graphs of y = 1/x and y=5/x+6 compare?

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?

Parabolas y=−2x^2 and y=2x^2 +k intersect at points a and b that are in the third and the fourth quadrants respectively. find k if length of the segment ab is 5.
