<p>@sound, the asnwer was 91.</p>
<p>also, for the n=0 one, I dont know if you could do that but I just did it using algebra and I got the same answer</p>
<p>Yes i also got 91 for the average one.</p>
<p>can anyone remind me what the question was where the answer was 77? Because I see it on the list but I don’t remember getting that…</p>
<p>lol randomly bubbled 8521!</p>
<p>ii got 91 too…so confirmed i guess</p>
<p>graph one was -7a + 13 or something?</p>
<p>and why am I ■■■■■■■■? like…sub in 0 and you get the answer…but i felt like subbing in 1…:@…WOWOWWOWOW</p>
<p>91 is confirmed.</p>
<p>Really now, so who here “randomly” bubbled in 8521?</p>
<p>for the one that everyone put 8521 thats what i had at first then i changed it to 9522</p>
<p>For the x^3 one I remember just plugging in 2 for x and 1 for n and it worked. Did I just get really lucky that that worked?</p>
<p>@wong: you could put n=0 because it said nonnegative</p>
<p>@MIT, the answer was 26 because you found the total number of values and since it was an even number you know you have to take the average between 2 values. So you divide the number by 2 and take the next term as well. You then realize that this term is like 2855 and 2856 or something which are both 26, so 26+26 /2 = 26</p>
<p>@Linger you could plug in because if the equation is true (which it states so it mus have been), then all positive real values would have worked.</p>
<p>I really hope this was experimental…did anyone have the question with the graph with x-intercepts 1 and 3 that had a maximum at (2,2). it asked for sum of y-intercepts of result of reflection about line y=x.??</p>
<p>I missed one then. Ah crap. Bye bye good score.</p>
<p>@awdr that was experimental.</p>
<p>anyone wanna reproduce that q. about n=0…and w/e? I wanna see why when I subbed in n=1 and x=2 it didn’t work.</p>
<p>i think i missed one…hopefully…what would the curve be…? any guesses/predictions?</p>
<p>REally viggy cuz it def worked for me. Maybe an arithmetic error?</p>
<p>shahe reproduced it, go back 1 or 2 pages.</p>
<p>n had to be in order the solution to be x^3, so you got 2x + x^2</p>
<p>and I missed the mean one too. Crap. that’s 2 I missed.</p>
<p>@viggyram, it was 2x^n+1+X^N+2=X^n+3. rewrite the exponents as powers of the sums. so 2(x^n*x^1)+x^nx^2=x^nx^3 then cancel stuff and solve.</p>
<p>According to what people said, that should be a 760ish</p>
