Answer:
b=15
How I got it:
32 + (7x4) = 32 + 28 = 60
60 divided by 4 = 15
Checking:
15 - 7 = 8
8 x 4 = 32
32 = 32
<em>You can tell b = 15 is the correct answer.</em>
-4,-4 - 9,-1 is the answer, i think
Certin, because they can be any two cards.
Letter B would be the correct answer
No this is not a function because 4 is used twice on the y side
