Hello Irina,

y = x-1

Lets assume x = 2 then y=1

Choices e,d,c, are wrong

Since y has to be positive then y cannot be equal to zero.

But I'm guessing this is what you already got.

B. Y has to be +ve, so Y is > 0.

we could make it little more interesting:

A) x > -1
B) x > = 0
C) x > 0
D) x > 1
E) x > 2

Hi,

AO is B.

By solving the inequality I also got B, but the changed to C, cuz y>0 includes fractions between zero and 1, meanwhile the stem says y and x are intengers. Wud appreciate your further comments.

x and y are +ve consecutive integers.

I got it, thank you Fistail!

Stem already says that y is not a fraction, little confusing, but i understand.

Should be D since x > y, x cannot be even 1. so x is 2 or > 2.

Argghhh I remember this question. accidentally hit C when I meant B.

Anyway its easy to see the answer.

The main stem says: x and y are POSITIVE CONSECTIVE INTEGERS.

So only B holds. b/c...

A: says that y can be 0. 0 is not a positive value
C: y can be 1.
D and E are just silly.
