Answer:

Step-by-step explanation:







For this case we have the following inequality:

To solve, we follow the steps below:
We divide between 5 on both sides of the inequality:

We multiply by -1 on both sides taking into account that the sense of inequality changes:

Thus, the solution is given by all values of "y" greater than or equal to 3.
Answer:

The vertical axis represents the "y" axis
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
The formula for the volume of a cube is length times width times height. Since the sides of a cube are all the same, it would be 12 cubed (12 x 12 x 12). The answer is 1,728 centimeters cubed.
