Check the explanation
Step-by-step explanation:
US has a comparative advantage in producing rice.
This means US's opportunity cost of producing rice is less than that of Korea.
Korea's opportunity cost of producing rice will be given as:
For producing 9 units of Rice, Korea gives up 5 cars.
For producing 1 unit of rice's, Korea will give up 5/9 units of car.

Answer:
A
Step-by-step explanation:
In this question, we are concerned with selecting which of the options best represents the difference of two squares.
Let’s have an exposition below as follows;
Consider two numbers, which are perfect squares and can be expressed as a square of their square roots;
a^2 and b^2
where a and b represents the square roots of the numbers respectively.
Inserting a difference between the two, we have;
a^2 - b^2
Now by applying the difference of two squares, these numbers will become;
a^2 - b^2 = (a + b)(a-b)
So our answer out of the options will be that option that could be expressed as above.
The correct answer to this is option A
Kindly note that;
x^2 -9 can be expressed as x^2 - 3^2 and consequently, this can be written as;
(x-3)(x + 3)
Answer:
{x,y} = {1/3,1/9}
Step-by-step explanation:
Solution :
{x,y} = {1/3,1/9}
System of Linear Equations entered :
[1] 4x + 6y = 2
[2] -4x + 3y = -1
Graphic Representation of the Equations :
6y + 4x = 2 3y - 4x = -1
Solve by Substitution :
// Solve equation [2] for the variable y
[2] 3y = 4x - 1
[2] y = 4x/3 - 1/3
// Plug this in for variable y in equation [1]
[1] 4x + 6•(4x/3-1/3) = 2
[1] 12x = 4
// Solve equation [1] for the variable x
[1] 12x = 4
[1] x = 1/3
// By now we know this much :
x = 1/3
y = 4x/3-1/3
// Use the x value to solve for y
y = (4/3)(1/3)-1/3 = 1/9
Solution :
{x,y} = {1/3,1/9}
