find the equation of the line that is perpendicular to y= -1/5x-3 and contains the point (1,2) answer all boxes please

Y = 5x -3

Step-by-step explanation:

Let's look for the gradient to solve this question for.

We are given y= -1/5x-3

Any line perpendicular to the above line will have a graient of m'.

Where mm'= -1

m = -1/5 from the line equation

So

mm'= -1

-1/5m'= -1

m' =5

For the equation of point (1,2)

(Y-y1)/(x-x1) = m'

(Y-2)/(x-1)= 5

Y-2= 5x -5

Y = 5x -3

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

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
