<p>it couldn’t have been positive b, there was a post that explained the problem. b had already been negative before.</p>
<p>ya if you plug in numbers you plug in a negative number for b because it was less than zero. Then if you plugged in lets say -5 for b, the result was -5 meaning that the answer was just b, not the opposite of b.</p>
<p>Use a=6 and b=-7. Solve it. It’s positive b.</p>
<p>When you solve, you get -7. Even though it’s a negative number, it’s still positive b since b was initially negative.</p>
<p>the asnwer was positive, you could of either plugged in values or even simplified the expression.</p>
<p>But wasn’t b itself <0 or something?</p>
<p>It’s negative b, just solve it algebraically.</p>
<p>I don’t remember the equation anymore, though.</p>
<p>for the 5 points on a line, and how many possible line segments:
the problem is essentially a combination problem.
So: it’s 10 combinations, taken 2 at a time = 10!/(2!8!) = 10
But unlike what RocknPiano said, it is NOT just n*2.</p>
<p>“Graph shift, f(x) = f(x-2) + 3: two to the right, three up”</p>
<p>Isnt the answer f(x+2)?</p>
<p>(abs(b)-abs(ab))/(abs(a)-1)</p>
<p>a>0, b<0. Let’s say a=6 and b=-7</p>
<p>(7-42)/(6-1)</p>
<p>-35/5</p>
<p>-7</p>
<p>-7=+b</p>
<p>wait i am not sure anymore, i need to see the problem again. w/e. >.<</p>
<p>If I omitted 10 questions, what’s the highest score I could get?</p>
<p>it was -b if you solved algebraically. I’m looking at mid 700s. I guess I’m gonna retake in october.</p>
<p>Oh wait a second, it’s clearly +b. I’m not sure if I missed that one or not, I really hope not. Solving algebraically gives you +b… yet I remember putting -b. Oh shoot, I think I did miss it.</p>
<p>I thought it was the absolute value of the entire top part of the equation, not just the separate parts.</p>
<p>Edit: Oh wait, nevermind. I just redid the problem and the answer is +b. Now that I remember, I put +b, not -b.</p>
<p>Okay I am really freaking out now. Math should be my strongest subject yet I’ve already missed two on this test. I know 44 is supposedly the 800 and I currently have a 47.5… was this easy? hard? How will the curve be? I really need an 800 on this.</p>
<p>yeah that makes sense, it is +b, whew, got a bit lucky right there lol</p>
<p>3134… I don’t think that’s the right equation</p>
<p>The sheer fact that I got a B in geometry, A- (or A? can’t remember) in Algebra II, and A- in Pre-Calc with 800’s on SAT Reasoning Math and likely SAT II Math hopefully will tell GT that I am, indeed, in a rigorous school. All you guys with the same grades that I’m reading about are saying you got low 700s.</p>
<p>what was the answer to n(n+1)(n+2)??</p>
<p>For those that are arguing about the GPA vs. SAT score, remember that the SAT, and SAT math II are both intelligence based. The math II not as much, but it has so many analytical-spatial-logic stuff.</p>
