Answer:
15 49-cent stamps
Step-by-step explanation:
We can solve this problem with the equations <em>0.49(x) + 0.21(y) = 9.45 </em>and <em>x - 5 = y</em>. Well, 0.49(15) + 0.21(10) = 9.45, so we know that there are 15 49-cent stamps and 10 21-cent stamps. The question is asking for the number of 49-cent stamps, so we can tell Travis bought 15 49-cent stamps.

In order to be a function, you canNOT have any duplicate x's.
A) x = -2, 6, 6, 10 --> 6 is used twice so it is not a function
B) x = -2, 10, 6, 10 --> 10 is used twice so it is not a function
C) x = -2, 1, 6, 10 --> all the x's are different. This is a function!!!
D) x = -2, 1, 6, 1 --> 1 is used twice so it is not a function
