Question

Please help!! i need to know if my answer is right.



Which point lies in the solution set for the following system of inequalities?
y > x + 4
y > -x + 2

(1, 6)

(-2, -1)

(-3, 2)

(1, 1)
My answer : B

Answer 1

well, let's test B

(-2, -1) => x = -2 y = -1

1st inequality
y > x + 4
(-1) > (-2) + 4
-1 > 2

# so now, is -1 really bigger than 2 ?

Answer 2

No so it can't be B. My other guess would be D.

Answer 3

Answer 4

well, you're not supposed to be guessing :|
you're supposed to test them, each one.. you think is D, well, test D then

Answer 5

1 > 1 I think that's right. :p I will just go with that.

Answer 6

1 > 1? hehe
so 1 is bigger than itself?

how can a number be bigger than itself?

Answer 7

\(\bf 1 \ge 1\) would be valid 1 > 1, is not

Answer 8

:p i guess your right. I'm new to this stuff >..<

Answer 9

so I guess is not D, though not a guess per se k=)

Answer 10

-3 > 2 isn't it either.

Answer 11

nope, 2 > -3

Answer 12

-3 is smaller than 2, so no dice on that one either

Answer 13

No it would have to be A.

Answer 14

hmm, how are you testing?

Answer 15

I just used what you showed me.
