Y = 7x + 3
Find the x and y intercepts of the line

The x-intercept of the line is

The y-intercept of the line is 3

Step-by-step explanation:

If the equation of a line is y = m x + b, then

Let us use these facts to solve the question

∵ y = 7x + 3

→ Substitute y by 0 to find the x-intercept

∵ y = 0

∴ 0 = 7x + 3

→ Subtract 3 from both sides

∵ 0 - 3 = 7x + 3 - 3

∴ -3 = 7x

→ Divide both sides by 7 to find x

∵ =

∴ = x

∴ The x-intercept of the line is  

∵ y = 7x + 3

→ Substitute x by 0 to find the y-intercept

∵ x = 0

∴ y = 7(0) + 3

∴ y = 0 + 3

∴ y = 3

∴ The y-intercept of the line is 3

step-by-step explanation:

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
