<p>Does anyone remember what the question was that had 9 as an answer?</p>
<p>Two Equation Q</p>
<p>(x + 2y) = 3</p>
<p>x^2 + 4xy + 4y^2</p>
<p>If you simplify the second equation, you realize it's (x + 2y)^2 so then it's 3^2 = 9</p>
<p>EUGH, but aw man, i think i only realized that afterwards, and now i don't know if i changed the answer</p>
<p>JimShaw: I got that the x^(3/2) thing was all of them:</p>
<p>I. "x radical x" is correct
II. "radical x^3" is correct
III. "(x^2)/radical x" is correct too.</p>
<p>Please correct me if I'm wrong, which isn't that improbable...</p>
<p>The U.S history thread is longer than this. THIS IS SAD! Come on people post post post!</p>
<p>jmarsh, i plugged in a number, and got all 3, is that right?</p>
<p>well, this topic has also splintered off into 3 topics to address the problem of experimentals. That can also be a reason why it's significantly shorter</p>
<p>does anyone remember the absolute value one with x on a number line
what where the three choices?</p>
<p>The axle question was 2n +2 right?</p>
<p>Jmarsh, yeah i think it is all three.</p>
<p>no, plmok, it was 2n-2 becasue you had to subtract 2 dollars because for the first two axles its two for one</p>
<p>I plugged in a number too and got all three</p>
<p>icedkiwis, i remember getting 9 as an answer to that question, but was it a grid in? also, which grid in question had 7 as an answer?</p>
<p>3/5 was the answer to which grid in question?</p>
<p>i dont remember if i put 3/4 or 3/5 anyone remember the question or their answer?</p>
<p>and what about the intersecting lines problem where you had to solve for a</p>
<p>and does anyone remember the absolute value one with x?</p>
<p>lbtg-- the intersecting lines one, i think it asked for the slope, not for a. i think the answerd was 5/4 or smthng.</p>
<p>3/5...was that the question about how much of the rectangle was shaded?</p>
<p>absolute value one 2/x<2</p>
<p>intersection lines the point was -.4, 2.2</p>
<p>Okay, but wouldnt it be 3/4? How would you possibly get 3/5?</p>
<p>iced no thats a different questions</p>
<p>the one im talking about says the interstion of lines are at(a,b) and asked you to solve for a
the first choice was
a=b
i think i put a=2b-4 or something which was E</p>
<p>and no descending 3/4 of that rectangle was shaded- that wasnt a grid in</p>
