In triangle abc, z is the centroid. show all work. given: az = 9 and cn = 5.5. a. what does it mean that z is the centroid and what does it tell us about segments an, bo, and cm? b. calculate the value of cb.

A: If Z is the centroid, it means that it is the median to all segments it is on.

B: CN = 5.5 , we know that the given long end of a segment is 2 times the size of a whole (which , in total, is divided into 3 parts).

AZ = 9, since its a long side, 4.5 is half of that given line (AZ). Which means that the continuation of that whole line AN, which is ZN, is also 4.5. Hence, CB = 4.5•3= (13.5)

Step-by-step explanation:

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
