<p>^ thats wat i put wow lol sugarincarnate we’re getting the same answers on like all the problems…btw did you get the f(2) and ax(c-d) questions? because i didnt</p>

122

<p>I put 9 super</p>

123

<p>The 2xc - 2xd + ad - ac with c-d =-2 and 2x-a = 4 WAS -8</p>

124

<p>i def. didnt have that problem</p>

125

<p>reeya91, its never not enough information. ever. princeton review class said so. consensus here is its -1</p>

126

<p>did you guys get 9 for the question where you flip triangle over y=9?
20 consective numbers = 2r+100
graph false = years later than 1994 is always lower than previous years
x = y = 1/8</p>

<p>…btw guys there was DEFINITELY two versions of the test, because a lot of the questions u guys are talking about i didnt get</p>

127

<p>ok then it was -8 yes</p>

128

<p>ya santa agree with all of those</p>

129

<p>if F(-x)=-F(x), then what does F(2) equal …
or whatever it was.</p>

<p>F(2) = 1</p>

130

<p>What did you guys get for the question asking for the median of consecutive integers …</p>

<p>I skipped that problem, came back to it at the end, but ran just short of time. I half-guessed and put 19.</p>

<p>Was 19 correct?</p>

131

<p>9 isn’t an answer choice though</p>

132

<p>Really? In some of my big blue book practice tests the answer was not enough information.</p>

<p>How would you get -1? There wasn’t enough information at all…</p>

133

<p>llkll it was 20</p>

134

<p>anybody remembers the grid in answers?</p>

135

<p>haha wow, i didnt have a lot of the questions posted here. for november sat, i got 4 wrong and ended up with a 690! :(</p>

136

<p>…darn.</p>

<p>I got a 690 last time. It looks like I got 700 or less this time around.</p>

<p>Oh well.</p>

137

<p>Can anyone explain the</p>

<p>if F(-x)=-F(x), then what does F(2) equal …</p>

<p>I said there wasn’t enough information</p>

<p>It was 1. Test it. If f(2) = 1 then F(-2) needs to equal -1. 1 - 2 = -1</p>

138

<p>the answer for that question was 1…because 1-2=-1</p>

139

<p>does anyone have a definitive answer or explanation on the angles (the 1,2,3,4) problem - I put angle 3 is the same as angle 1, but I definitely got stuck on that one</p>

140

<p>more questions:

  • ratio of cube faces shown (shows 3) of total = 1/2
  • dimension of rectangle with area 12 (shows 6 smaller rectangles with dimensions 2x1) = 12x1
  • ratio circumfirance of smaller circle to larger one = 1/3
  • n>1, k<1 = 1/(n-2) < 1/(k+1) (not completely sure)
  • 6 ppl tournament 2 times each = 30</p>
