Is the system of equations is consistent, consistent and coincident, or inconsistent? y=−3x+1 2y=−6x+2

To determine which among the given choices best fit as the description of the equations of the line, we determine the relationship between their slopes. In a slope-intercept form of the line such as,

   y = mx + b

m is the slope.

The value of the slope of the first equation is -3 and that of the second equation is also -3. Then, we look into their y-intercept, b.

The y-intercept ofhte first equation is 1 and that of the second equation is also 1. Since both lines have the same slope and y-intercept, they are said to be COINCIDENT.

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
