Plz help does the point (-1, -1) lie on the line y= 4x + 3 ?

yes, it does

Step-by-step explanation:

point (-1, -1)

if (-1, -1) lies on this line, it will make below equation correct:

Answer is yes

Yes it does.

Step-by-step explanation:

For (-1, -1) to lie on the line y= 4x + 3 ; that would mean substituting x=-1 into the expression we should be able to get y=-1 so let's test that.

Substituting x=-1 in y= 4x + 3;

we have : y= 4(-1)+ 3 = -4 +3 = -1;

Since y=-1 tallies with the point (-1, -1)

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
