<p>1.5 is right.</p>

<p>the flipping over the x-axis problem for math</p>

<p>x+2y=-1 right? (answer choice B)</p>

<p>no, 0 is an integer, but not an even one. the answer was 1998. i'm not sure why people had trouble with this - i had trouble with 2 on section 1: the area of circle in square (i had to resort to guessing .. how sad) and the one with the girl and not being in one club, so what phrase would make us found out if she's in the hiking club</p>

<p>^
Yeah, that's right. It's impossible for two circles to intersect more than twice.</p>

<p>Oh, were you asking about the max of the parabola one? Yeah, that one is 1.5 since the maximum will be at the very middle where the sign change begins.</p>

<p>yay.
For the even interfer - What is the difference between the 1st and last 1000 even numbers
something like that.,
so i did 1000x2=2000 1x2=2 2000-2=1998</p>

<p>The girl in the club, I think the statement was: "No one who is not in the outdoors club is in the hiking club."</p>

<p>Question: Does being a National Merit Finalist [not semi-finalist] depend on state?</p>

<p>i think the max number two circles to intersect is four, but since one of the radius's was half of the other, the max was two in this case</p>

<p>for the flipping over x-axis, does anyone remember the original equation?</p>

<p>I'm absolutely sure the answer was something like " if she isn't a member of club a, then she isn't a member of club b".</p>

<p>x-2y=1 i think......</p>

<p>ya it was x+2y = 1 but when flipped, it was x + 2y = -1 i believe.</p>

<p>@zoax: yes.</p>

<p>question - the girl in the hiking club.
was the answer that whoever isnot in the hiking club does not go hiking?</p>

<p>ingette-dontremember sorry</p>

<p>I believe the equation was 2y-x=1 or y= x/2 + 1/2</p>

<p>Max would be infinite, no, if they have the same radius?</p>

<p>i'm pretty sure cb wouldn't use a double neg on the sat. but i agree with concept.</p>

<p>yes it depends on state</p>

<p>The answer to the even integer in 2000 one is 1998. 0 is not an even integer (it's nothing) thus 2000 - 2 = 1998.</p>

<p>Original equation for the reflection line is x + 2y = -1, I think?</p>

<p>also - for the intersection of 2 circles, the answer was 2 correct?</p>
