<p>I put them up there</p>
<p>|3x-2| = -|x+21|</p>
<p>Try squaring both sides to find out if theres a solution algebraically!</p>
<p>to everyone, the absolute value equation has no solutions. a solution means an intersection point but when you graph it, they do not intersect. one goes infinitely in the positive direction and the other in the negative direction.</p>
<p>i have a new question. for the one where it was n > 1 when (equation), what is p? does anyone remember the EXACT equation? i feel like when you plugged in 1 into the unknown equation, p = 3 when when you plugged in 2 into the unknown equation, p = 11. i think that is why i put down p is odd & > 3… but i frankly dont remember much…</p>
<p>so far, i have 4 wrong and 0 omit. i know thats an 800 still but does anyone know what the limit is? is it 6 wrong or 5 wrong? I’m scared that I simply added or multiplied wrong. :(</p>
<p>^which problem was that? numebr i mean</p>
<p>If 7^a = 49^b
7^a = 7^2(b)
7^a = 7^2b
in which case a= 2b
So a=2b is correct! There was a log option which was wrong!</p>
<p>for the 7^b = 49^a or whatever, the question was asking which of the following is FALSE? and the log one IS true… 7^b = 49^a is the same thing as b log 7 = a log 49. i think the right answer was D (?) not 100% sure. idr the exact answer, but i know A&B&E were right</p>
<p>the number question was like if p = 2 - 1(-1)fklkfdslkjdf (i dont remember the eq) , and n > 1, p is…?
and the options were:
p is odd
p is odd & > 3
p is odd & > 5
p is even
p can be anything</p>

<p>Im pretty sure, the answer to the 7^a = 49^b thing was B because I tried the others, they all work</p>
<p>Never mind lol, the 1st side yields 16.25 while the other is -16.25</p>
<p>yeh, my bad. lost the sign change lol</p>
<p>Wait need some more clarification, one of the problems gave you 3 equations and asked which had f(x) >= 0 for x=all reals. Was the 3rd equation</p>
<p>tan squared (x) - 1
or
tan squared(x-1)</p>
<p>I think it was tan squared(x-1).</p>
<p>fortunately i took a breather after sats so i havent really touched my calculator XD
anyways, for the p one the equation is:
P=n+(n^2-1)^((1-(-1)^n)/2)
if the condition was n>1
isn’t p=3 at n=2?</p>
<p>oh and i thought it was tan^2(x)-1 
…because i remember saying that it wasnt going to be always positive…>.> maybe i saw/remember it wrong</p>
<p>I believe it was tan^2(x) - 1, distinctly recall checking it on my graph for tan^2(x), then answering that it at some point is negative because tan^2(x) = 0 where x = 0, thus, 0 -1 = -1, and -1 < 0.</p>
<p>I might be thinking about the wrong question then… Can someone clarify what exactly it said?</p>
<p>Was it a I, II, III question?</p>
<p>it was definitely p is odd. </p>
<p>Anyone know what a 40 raw score will get me? any chance of a 780?</p>

<p>Honestly, I wouldn’t bother retaking a 770.</p>
