<p>omg was it xy=-8???!! i thought it was obvious until i saw all tht absolue value garbage lol</p>
<p>no the x had to be in an absolute value bar, because it has to be positive</p>
<p>ace 22 tennis, A was the correct answer.</p>
<p>how did you find 19 for the third side</p>
<p>The graph reflected across the x-axis....I got xy = -8. I just graphed it on my calculator. I wasn't very sharp with math today.</p>
<p>oooooo for the xy = 8 one... i said the reflection of the equation over the x-axis would be xy = -8... did anyone else get that?</p>
<p>i got 6 for the base of the trapezoid.</p>
<p>it's xy = -8, i just plugged it into my calculator</p>
<p>x didn't have to be positive...did it?</p>
<p>oh man..i must've misread the conserving energy question!! oh well..physics is kinda difficult to pay attention to..</p>
<p>hmm making the x values always positive would make the y values always negative and the reflection should have had both negative and positive values for y</p>
<p>If X had to be in the a.v. bar then...DARN. UGhh. </p>
<p>You know what.. I really shouldn't have logged onto this site...haha...Totally killing me.</p>
<p>x didn't have to be positive... when u reflect individual points over the x-axis, you multiply the original y in (x1, y1) by -1, so that the new point is (x1, -y1). if y1 were a negative number initially, it would become a positive number</p>
<p>so no absolute value sign. answer was xy = -8</p>
<p>i thought since the point wwas being reflected over the x axis and it was previously in the first quatrant, it was now ging to be in the forth where x is positive and y is negative, 2 times -4 gives you -8</p>
<p>blood types? choice I and III. i^BB and i^B??</p>
<p>yea thats what i got</p>
<p>yeah, that's the right answer but i HATED how the test made u call upon concrete knowledge such as that... for my own sake, i was fine for the mitosis questions and the blood type question, but i hope they throw out the viscosity question</p>
<p>yes blood was I and III</p>
<p>please, i got that one wrong also, i was looking for the definition for a while and could not find it!</p>
<p>gymfreak123: i hope they throw that one out too! i took ap chem and we had to know that, but i still got it wrong..=[ but my point is that you had to take a class like ap chem to learn something like that, its not even taught in honors</p>
