The inequality 10x + 20y > 500 models all of the combinations of scores of 10 and 20 points that will give a total greater than 500 points in a game. what is not true about the values for x and y? a. they will whole numbers. b. they will be positive numbers. c. they will all be in the first quadrant. d. they will each be greater than 5.

The inequality shows that there x makes up the 10-point scores, and y makes up the 20-point scores. To know which of the choices cannot be true, we can analyze each choice:

A. It is not possible to have a fraction of a score, so this must be true.
B. They must be positive numbers. 
C. Similar to B, they must be positive numbers.
D. Even with a value less than 5, the inequality can be met. 

Therefore, the correct answer is D.
