(1) let "r" denote number of rabbits, "c" number of chickens

Set up the equations:

$r + c = 1000\\4r + 2c = 3150\\\\-2r -2c = -2000\\4r + 2c = 3150\\\\2r = 1150\implies r = 575\implies c = 425$

Answer: There are 575 rabbits and 425 chickens

(2) m - number of Mike's stamps, a - number of Andrew's stamps.

Set up equations:

$m = 4a\\m-8 = 2(a+8)\\\\4a-8=2a + 16\\2a = 24\implies a = 12\implies m = 48\\$

Answer: Mike has 48 stamps. Andrew has 12 stamps.

Does the following represent a function? f = [ (3, -1), (2, 5), (4, -6), (3, 4), (5, -8) ]

ella [17]

Answer:

Not a function

Since x= produces y- -1 and y=-4, the relation (3,-1),(2,5),(4,-6),(3,4),(5,-8) is not a function.
