<p>what was the question that had "the answer cannot be determined" as an answer choice? i can't remember whether or not i put that down.</p>
<p>What happened to all the <plug equations="" into="" solver=""> problems???? It seemed like the practice tests had WAYYYY more of those than the real test.</plug></p>
<p>@artstar: all I remember was that answer could be determined.. don't rem anythin else..</p>
<p>counterexample was 6. 6 and 30 were only ones where both 2 and 3 were actually factors, and in 30, 5 (2+3) actually is a factor</p>
<hr>
<p>yup.. I agree with nick..</p>
<p>yeah i don't think i picked that as a choice, but i remember contemplating it. i'd still like it if anyone could tell me what the question was.</p>
<p>...................</p>
<p>well.. there was no time left.. or els I would have definitely tried Y/(2x-y)=10 and X/(2y-x)=?</p>
<p>@rashi i think that the question had bad wording, i remember reading the "could" but i'm thought it suggested that it worked in all cases. </p>
<p>Anyone remember the polar question asking points that are NOT equal to (1,pi/2) or something like that???? I really would like to know the answer. I put (-1,-5pi/something--i think it was 4)</p>
<p>plug-in was the fastest way to do the X/y question imo</p>
<p>does anyone remember the question about the roots of some equation? it asked which equation had s+1 and r+1 roots. it was easy but i was literally working on that question on the last second and so im not sure if what i put was right.</p>
<p>oh atomicbomb i put the same answer as you.</p>
<p>@sillbill: 5 and 7 > 2 and 5+7+1=13 that is again prime.. so the ans was r+s+1</p>
<p>I had prob with that r+1 and s+1 roots..</p>
<p>Right, but it said that it would work as a rule, not as an exception. Unless it works for all primes > 2, I don't think that it was correct. How could they expect us to try and try until we come up with an example that eventually works for one of them? They wouldn't.</p>
<p>@art_star thats a relief.</p>
<p>For that question i can't help u cuz i solved the equation using Polysmlt and then plugged into the equations where the roots+1 worked. I think i put D though (maybe C), but thats really stretching my photographic memory to its limits.</p>
<p>i remember putting choice B...but if only i remembered what the equation was! i think it was x^2 +9x+ something. it definitely had a nine and i THINK a 4</p>
<p>i just put them on the graphing calculator and kinda estimated. anyway, im sure the tests have the answer choices mixed up.</p>
<p>.................</p>
<p>@sillbill: It said that the following rules could be possible.. but newa.. wot was the ans to the roots ques..?????</p>
<h1>50, 2 seconds?</h1>
<p>ok so the polar coordinates one was I believe the one with (1,13pi/4) (the last one). Unless the first part of that one was -1, which I'm now thinking I may have misread, that answer would point you to a point in the third quadrant</p>
