It has been estimated that one million people are added to the world's population every 4.5 days. Use this rate to answer the following question. How many babies to the nearest million are added each year?

81 million

Step-by-step explanation:

In one year there is 365 days, if you divide 365/4.5 the answer is 81.1. And every 4.5 days add 1 million people, then you multiply

81.1*1 000 000 = 81 100 000

approaching to the nearest million, 81 million of babies are added each year.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
