Answer:
21. B. Graph Z
23. A. neither function nor relation
24. D. relation only
Step-by-step explanation:
21. Graph Z is the only graph which does not pass the vertical line test
23. The graph does not pass the vertical line test, AND it is not merely given x and y points like a relation. It is graphed as a squiggly line with no given x and y points, therefore you could not make a relation from it either.
24. There is an x value of -4 twice, meaning the set does not pass the vertical line test, HOWEVER, it is a given collection of x and y values, making it a relation.
I would appreciate brainliest, have an amazing day

Answer:
C. 14 inches
Step-by-step explanation:
The perimeter is double the sum of length and width:
P = 2((4a +3) +(6b -2) = 8a +12b +2
For the given values, this is ...
P = 8(0.75) +12(0.50) +2 = 6 + 6 + 2 = 14
The perimeter is 14 inches.
