Answer:

Option 1, 2 and 4

Step-by-step explanation:

3x-4y-8= 12

3x-4y= 12+8 (bring constants to 1 side)

3x-4y= 20 (simplify)

For a point to be a solution of the above equation, substitute the x and y coordinates into 3x-4y and see if it equals to 20.

Option 1: (0, -5)

3(0)-4(-5)= 20

3(4)-4(-2)=20

This is correct

3) (8,2)

3(8)-4(2)= 16

This is incorrect.

4) (-16, -17)

3(-16)-4(-17)= 20

This is correct.

5) (-1, -8)

3(-1)-4(-8)= 29

This is incorrect.

For China: 1,545,744,200

For Mexico: 145,507,500

For Zaire: 92,237,875

Step-by-step explanation:

For Australia: Population in 2000 is 19,169,000 and it is increasing steadily at a rate of 0.6% per year.

Therefore, the population in the year 2025 will be

$19169000[1+\frac{0.6 \times 25}{100} ]= 22,044,350$ (Answer)

For China: Population in 2000 is 1,261,832,000 and it is increasing steadily at a rate of 0.9% per year.

Therefore, the population in the year 2025 will be

$1261832000[1+\frac{0.9 \times 25}{100} ]= 1,545,744,200$ (Answer)

For Mexico: Population in 2000 is 100,350,000 and it is increasing steadily at a rate of 1.8% per year.

Therefore, the population in the year 2025 will be

$100350000[1+\frac{1.8 \times 25}{100} ]= 145,507,500$ (Answer)

For Zaire: Population in 2000 is 51,965,000 and it is increasing steadily at a rate of 3.1% per year.

Therefore, the population in the year 2025 will be

$51965000[1+\frac{3.1 \times 25}{100} ]= 92,237,875$ (Answer)
