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?
It looks like you're missing part of the question, like some options for things that aren't true? Otherwise about the only thing you can conclude is that x and y are probably both nonnegative, since one normally doesn't lose points in most games.
