Which set of ordered pairs shows a function? O A. {(2, 3), (2, 6), (2, 9). (2, 12), (2, 15) }
O B. {(2, 6), (-3,6), (-8, 11), (6, 2) (9,-7))
O c. {(3, -5), (4, -4), (5,-3), (4, -2). (3, -1)}
O D. {(3, 8), (-3,2), (-6,0), (-3, -2), (3,-8)}

B, hope this helps!

Step-by-step explanation:

Functions can not have repeating X values.

O B. {(2, 6), (-3,6), (-8,11), (6, 2) (9,-7)}

Step-by-step explanation:

answer: 40.95

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
