A. y=-2x-4

b. y=2x-4

c. y=-4x+2

d. y=4x+2

B

Step-by-step explanation:

(x,y) so you have positive 2 for x, and on the y axis, the line goes through -4, so thats your y, so it will become y=2x-4

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

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
