Answer:
The land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively
Step-by-step explanation:
Let the area of Country B be x
We are given that Country A is larger by 473 square kilometers.
Area of Country A = x+473
Total area of both countries = x+x+473
Total area of both countries = 2x+473
We are given that The combined land area of the countries A and B is 159,973 square kilometers.
So, 
x=79750
Area of Country A = x+473=79750+473=80223 sq.km.
Hence the land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively
2x + 5y = -8 . . . (1)
-133x - 4y = -8 . . . (2)
(1) * 4 => 8x + 20y = -32 . . . (3)
(2) * -5 => -665x + 20y = 32 . . . (4)
(3) - (4) => 673x = 0
x = 0
From (1), 2(0) + 5y = -8
5y = -8
y = -8/5

<u>Answer:</u>
No, the given set of pairs does not represent a function
<u>Step-by-step explanation:</u>
For a set of values to be a function, each input must have one and only one output value
Now, for the given set, we can note that:
The input -13 has two output values; 4 and 9
<u>Therefore</u>, this set is not a function
Hope this helps :)
