it asks if \(xy>0\) right?

Answer 4

the only way for the product of two numbers to be positive is if

b) they are both negative

Answer 5

yep
and xy<0 and x/y<0 and x/y>0

Answer 6

ok so your looking at the x and y for the positive and negative?

Answer 7

you lost me

Answer 8

the question states that the product of the two numbers is positive
that means they could both be positive, like \(2\times 3=6\) or they could both be negative, like \((-2)\times(-3)=6\)

Answer 9

ok i get that

Answer 10

if one is negative and the other positive, then when you multiply them you will get a negative number

Answer 11

and the question has part a,b,c,and d xy>0 is part A, then there is xy<0 and x/y<0 and x/y>0

Answer 12

ok did you get that if \(xy>0\) then there are two choices ?

Answer 13

yah sorry i just got it, took me a while!
