<p>physicsboy:
are you referring to the ellipse question?</p>
<ol>
<li>can u provide more info on this 1? i dont remember it</li>
<li>it can be odd or even, it does not have to a multiple of 8 and 3, i forgot the 3rd one</li>
</ol>
<p>i think the odd or even statement was the only true one?</p>
<p>I think the line had to go through the origin and be parallel to a line with equation 2x-y=1.</p>
<p>If I remember correctly the third one was that the score cannot be 13 right?</p>
<p>The third option was that it was possible to optain a total score of some number around 11 (=3+8), but that wasn’t 11, so it wasn’t possible</p>
<p>@dawgy</p>
<p>yea i think ur rite</p>
<p>2x-y=0 it had to go through the origin too. i dont think thats the exact equation though</p>
<p>How about the one about which values for a and c would make ax^2 + bx+c=0 have two real roots?</p>
<p>Are any of you keeping track of how many more we’re missing?</p>
<p>it was -3 and -1</p>
<p>b^2-4ac < 0</p>
<p>i think it was E? not sure. i ended up graphing out all the possibilities lol</p>
<p>yea E is correct</p>
<p>Physicsboy: you and I make a good team, I remember questions vaguely and you fill in the details, which in turn helps me remember more about the question :)</p>
<p>;D</p>
<p>10 char</p>
<p>and every five posts I ask if I can still get 700 
lol</p>
<p>How about the one about symmetry with respect to x=3?</p>
<p>And with every answer revelation, I get more and more depressed.</p>
<p>Hiking: I remember that one. I put like 1, but my basis for that answer was a whim… lol</p>
<p>ok it has to be symmetric so i thought of the parabola y = (x-3)^2 + c
i plugged in the point =p</p>
<p>i really hope im right on this, took me some time =p</p>
<p>@Hiking7610 oohhh I forgot about that question… I think I made a mistake
There was a point I think it was (-1;1) and I put (7;1)</p>
<p>edit: parabola??? ops</p>
<p>The answer to the reflecting for (3,2) about y=-x is actually (-2,-3).

<p>Sorry I couldn’t contribute more… track practice…</p>
