Determine which of these relations are transitive. The variables x, y, x', y represent integers A.x~y if and only if x +y is pos
itive. B. (x, y)~(x/.y/) if and only if x+yx+y C.x~y if and only if xy 2 0 D.x~y if and only if x + y is even. Ex~y if and only if xy is negative. Fx~y if and only if x-y is a multiple of 10.
<span>zebra fish a then tetras fish (11 – a)
2.2a + 1.85(11 – a) = 22.80
2.2a + 20.35 – 1.85a = 22.80
0.35a = 2.45
a = 7 zebra and 11 – 7 = 4 neon fish
