choose the pair of lines in the diagram that appear to be noncoplanar A.) AB and CB B.) DC and EB C.) CB and DC D.) XY and AB

15 units use socratic

step-by-step explanation: 15 units

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

the square root of what number? if you add that, then someone will probably answer the question.
