The function with a rate change of 3/2 whose graph passes through the point (4,10.5)

y= 3/2x +4.5

Step-by-step explanation:

If you plug the slope in a graphing calculator you can then guess and check to find the y intercept that gets you the coordinate (4,10.5)

30005

yes ok                                            

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
