In a plane, line n is parallel to line o, line o is parallel to p, and line l is perpendicular to line n. which must be true? n. which must be true?

The correct answer is:

Line L must be perpendicular to both line O and line P as well.

Explanation:

Since N, O and P are all parallel, any line that intersects N will intersect O and P at the same angle.  Since L is perpendicular to N, intersecting at a right angle, this means it must be perpendicular to O and P also.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
