DECEMBER 2008 SAT Subject Test: Math Level 2

<p>The 2^n and 4^m only had three ordered pairs that satisfied it: (n,m)= (0,0) (-2,-1) (2,1)</p>

<p>It asked how many ordered pairs BETWEEN -4 and 4 satisfied the equation.</p>

<p>There was an answer choice that said 1 - sin (x). I hope you didn't pick it :p</p>

<p>no it said -4 4 inclusive. I'm pretty sure. So was it 2/9 or not?</p>

<p>what about (1, 2) and (-1, -2)? im guessing those count as ordered pairs too right?</p>

I believe it said inclusive, didn't it? I think that includes -4 and 4. I put five.</p>

<p>I thought the x and y needed to correspond to m & n?</p>

<p>lol yeah it said inclusive, it was 5 possible.</p>

<p>Was 1-sin x even the right answer?</p>

<p>lolol that's the one with the 1- sin x. gl with the rest of your questions.</p>

<p>oh nvm...i got 5 because i counted 4 and -4 as inclusive</p>

<p>I don't think it was the right answer. That would be like 1 - the vertical line in your drawing.</p>

<p>its 1-cosx i believe</p>

<p>Oh, right, I was doing that problem for a bit got 1 - something weird then I skipped :/</p>

<p>i m hopin there was no choice 1 - sinx??? and only a 1 - cosx option</p>

<p>wait so it was 5 or 3......?!?!?!</p>

<p>and omg I put 1-cos(x)</p>

<p>a lot (in fact consecutive) c and d in tthe end?</p>

<p>It was definitely 5. I dunno about the consecutive answer choices in the end. I usually stress out when I see a pattern, and I didn't stress out.</p>
