Which of the following lines are parallel to the line y = 7x + 2/3?

y = -1/7x

y = - 1/7x - 12

y = 1/7x - 3/2

y = -7x + 3/2

pi x^2

step-by-step explanation:

pi times x squared

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
