<p>m x -1/m = -1</p>
<p>From wikipedia: </p>
<p>Comparisons</p>
<p>implication: if P then Q; first statement implies truth of second
inverse: if not P then not Q; negation of both statements
converse: if Q then P; reversal of both statements
contrapositive: if not Q then not P; reversal of negation of both statements
contradiction: if P then not Q; negation of second statement</p>
<p>@luca- yes that is correct</p>
<p>What number was the contrapositive? Like the >=3 thing. I had no idea on that one. </p>
<p>basketball, I got C and D for the ones u were talking about. you’re safe.</p>
<p>so ln(x)=e^-x</p>
<p>you should do this using a graph, seeing where graph intercepts, take that x and plug it into lnx.
however, algebraically,</p>
<p>ln(x)=1/e^(x)
ln(x)(e^x)=1
then use a ti89 solver, get 1.3098 for x,
do ln (1.3098),
=.2698
=.27</p>
<p>how would you go about solving it algebraically without ti89 solver?</p>
<p>How did u get “Perimeter of triangle on a cube with side length 7: 26.8”</p>
<p>And for
“Graph shift, f(x) = f(x-2) + 3: two to the right, three up”</p>
<p>It said it had to go 3 up?</p>
<p>the asnwer was (2,3) for that one</p>
<p>I don’t have time to read through all the posts, but what is the general consensus for the test? I thought it was harder than sparknotes… omitted 3 T_T</p>
<p>I thought it was incredibly easy. Not as easy as the one in the giant CB book, but definitely easier than Barron’s and SparkNotes.</p>
<p>another problem could be added:</p>
<p>5^2x-1=96</p>
<p>i think the answer was A. pretty straightforward problem.</p>
<p>wow the length of this thread double today lol</p>
<p>Hmmm well everyone I know is saying it was harder than usual 
I omitted 3… hopefully that pulls out an 800 :/</p>
<p>I’m cancelling mine…WHY AM I SO BAD AT STANDARDIZED TESTING, YET HAVE PERFECT GRADES? CAN ANYONE EXPLAIN THIS?</p>
<p>You have easy teachers? lol</p>
<p>lol me 2 i fail standardized tests but not cuz of easy teachers cuz im like in one of the toughest schools in the state</p>
<p>maybe you get too nervous or just blank out. try practicing in a real-environment so you’ll be better prepared</p>
<p>What is 3 omit, 1 wrong?</p>
<p>How many wrong would be the min for a 750?</p>
<p>oh and i don’t know how this correlates to easy teachers and grade inflation. i hate when people say that. some people don’t get things as easily as others yet it doesn’t mean the teachers are easy.</p>
<p>Kid 1: Has a 3.7. Works hard, studies, and really thrives to do his best at school. Does below average on his SATs.</p>
<p>Kid 2: 3.0. Average kid. Slacks off, just has the natural ability but doesn’t strive to do his best. Does amazing on his SATs. </p>
<p>I wouldn;t say that’s easy grading. Kid 1 just works harder, and therefore has a higher GPA. Some people just don’t do well on standardize testing. The valedictorian of my class got a 1230 on his SATs with a 3.75 GPA. His score was below of what was expected of him, yet he got into USC, Duke, UPenn, and was even wait listed to Stanford.</p>
<p>My school is a California Distinguished School with a very high API score. Trust me, its not easy.</p>
<p>I earn my grades through hard work and studying. And the teachers aren’t easy. In my chemistry class (honors btw), the highest grade you can receive is a 90% on a lab…if you do everything perfectly that is. </p>
<p>Basically, my grades in most or all of my classes is made of quizzes, tests, and a final exam.</p>
<p>History - 60% of grade is tests, quiz and final
English- 75% of grade is essays/projects on each book unit
H. Science- 60% projects and tests/quizzes
H Chemistry- 100% lab/quizzes/tests/final
Precalculus- 75% tests/quizes/final exam
Spanish - 55% tests/quizzes/final</p>
