True or False: The lines 4y-x=9 and 4x + y=-2 are perpendicular and intersect at the point (-1,2).

True

Step-by-step explanation:

the two equations graphed intersect at the point (-1,2) and are perpendicular according to the graph.

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.

Two because two of one thing is two.
