65 basketball cards because 260 split in to (divided) r groups equals 65
The answer is 12.5, but if you round it, it will most likely be 13, so the answer is C.13, hopes this helps!!:)
Y + 1 = -3(x - 5)
y + 1 = -3x + 15
y = -3x + 15 - 1
y = -3x + 14 <== or f(x) = -3x + 14
All you do is multiply 15 and 6 you get 90. then divide 90 by 9 and you get 10.
