Which ordered pair needs needs to be removed in order for the mapping to represent a function?
Fed [463]

Answer:

b - (-2,-1)

Step-by-step explanation:

A function is a mapping in which each element of the domain, or input, is mapped to one element of the range, or output.

In this mapping, the input value -2 is mapped to both 2 and -1; this makes the points (-2, 2) and (-2, -1).  If one of these two was removed, the mapping becomes a function.

The only one of these listed in the values given is (-2, -1).

Two linear equations are given below.
gladu [14]

Answer: You can't answer this, but here are some guidelines

Step-by-step explanation:

I would love to answer this question (coming from someone who has already completed algebra keystones) but I need to know what the linear equations are before I can. If the functions are reciprocals of one another (the slope is the opposite and the fraction is switched) it is a perpendicular line which means one solution.  If the slope is the same but the intercept is different (using y=mx+b) so if b is different but m is the same they are parallel and there is no solution. If they are the same line (same equation) there is infinite solutions. If this doesn't help I would suggest finding graph paper and trying it out and seeing the intersection points.
