Plug in each number

0: (1/2)*0+4 > 9
0+4>9
4>9-------Not true

4: (1/2)*4+4 > 9
2+4>9
6>9--------Not True

9: (1/2)*9+4 > 9
4.5+4 > 9
8.5 > 9-----Not true

10: (1/2)*10+4 > 9
5+4>9
9>9---------Not true

11: (1/2)*11+4>9
5.5+4>9
9.5>9-------Yes true

17: We already know this one is true from common sense hopefully.

So the only #s which were true are 11 and 17
