Please help me with math

By observing the graph we can note down the following things about the boundary line:

Let's look at the shaded region. The origin lies inside it.

Thus, the point $(0,0)$ satisfies the equation of the region.

Upon putting it in the options, we find that only two options: 2 and 4 satisfy the inequality $0<5$

Now find the Y-intercept of the boundary line:

Option 4) $0-2y=5$

$y=\frac{-5}{2}<-2$

Since it is smaller than -2, it is the wrong option.

Hence, correct option is $\boxed{x-3y<5}$

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

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0
