<p>what was the answer to the problem where the number was increasing by 8 and it was asking you to solve what N was equal too what the sum of the first N was 200? it was either 6 or 7. i put 6…</p>
<p>@silverspooon9449 hahhaha thats exactly what i did too, this test was unusually hard and so i didn’t know how to them so i guessed B for about 8 questions lol…im praying for a major curve</p>
<p>i think the answer was 7 for the arithmetic question</p>
<p>7
10 char</p>
<p>sequence
5,13,21,29,37,45,53=203
so 7th term is greater than 200</p>
<p>Wooo B buddies! With any luck we might get a few of them correct :P</p>
<p>what was the question about a circle and a triangle, and the triangle was a 5,12,13. WHat did it ask for?</p>
<p>it asked for the length of bc, which was the length of the radius (5) minus the total length of that side, which was thirteen. i believe answer was 8</p>
<p>Just for clarification to an earlier post, the answer to that abs(x+5) <-5 or something, it was the empty set. I don’t understand how it’s so difficult. Absolute value is positive. Thus, -5 is impossible…</p>
<p>The solution set was empty cause the absolute value of anything will never be less than a negative</p>
<p>Wait. Are you sure the problem was abs(x+5) </= -5? I’m almost positive it was abs(x+5) >/= -5.</p>
<p>I got the infinity<-7 3< infinity answer too. Which problem was that for?? There’s confusion about it.</p>
<p>Okay, the question with the absolute value of blahblahblah < -5 is definitely empty set. Unless that absolute value equation had a negative OUTSIDE of the absolute value symbol (lol what’s the mathematical term for those things), there’s no way it can equal a negative.</p>
<p>Um, any others that people remember?</p>
<p>I am positive that the -5 is not the right number its was like 3 or something abs(x+5) </= -5</p>
<p>What ever it is, I am positive that the answer is infinity<-7 3< infinity</p>
<p>Yeah. I think the right number might have been positive. Whatever it was, the answer was definately infinity<-7 3<infinity. I plugged in a lot of values to test my answer choice so I’m very confident that was the answer.</p>
<p>any internationals from Australia or form 69Bs here??</p>
<p>To clarify, the question currentyl under debate was:</p>
<p>Give the solution set of abs(x+2) ≤ -5 </p>
<p>I don’t remember if it was + or - 2, but either way, it’s irrelevant because the absolute value of any number must be positive. (Unless some of us had a slightly different question.) Perhaps those of you who claim there was a solution set did, or maybe the absolute value bars were overlooked.</p>
<p>why was the question for the arithmatic sequence? It was 5, 13, 21, 29, 37, 45, 53. I said it was 6 but it might have been 7. If someone remembers the question it will help a lot.</p>
<p>^It was 7. It asked to find the fewest terms required to make the sum of the sequence greater than or equal to 200. a1=5, a2=13, a3=18, etc. and if you add them up (or use the formula, which I personally forgot), you need the first 7 to break 200.</p>
<p>Didn’t it say it had to be LESS than 200 though? Or did I read it wrong?</p>
