Which best represents the solution set of all real numbers? [ [ PLEASE ANSWER , I'M CONFUSED ] ]

B.

Step-by-step explanation:

Since the solution set is all real numbers, our solution graph must cover the entire number line.

We can see that B contains the graph that extends infinitely in both directions,  thereby covering the entire number line.

Therefore, our answer is B.

A is not correct because it leaves out [-6, 1] (approximately).

C is not correct because it leaves out everything to the left of -7 and everything to the right of 1.

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
