<p>the balloon one was 4....</p>
<p>it was matching different color balloons for a party</p>
<p>Are you all sure about x-t+s being the answer to the books question?</p>
<p>lets say she has 5 books and if she adds 10 more books
(t), she will have 15 (x)....Instead of adding 10 books, she adds 5 (s), which means she has 10 books....so the answer would be x-s...</p>
<p>i thought it was x+s</p>
<p>Did Anyone have the question where it was slope formula </p>
<p>Y=MX+B</p>
<p>and you got a table</p>
<p>X - Y
2-4
8-8
20-16</p>
<p>and had to find the intercept (B)?</p>
<p>What about that intersecting squares one too....You would think the answer was 16 bc the area of the first sq was 64, but it didnt fit directly into 1/4 of the square you knew the area of and you had no idea what the area of the 2nd square was...Can someone explain that one to me as well? </p>
<p>It honestly stumped me because It didnt follow normal slope rules.</p>
<p>@ Tilgaham</p>
<p>for the y=mx + b, you had to find the slope first, after that you could find b using any of the points given</p>
<p>as for the 2 square one, the one square was just rotated a little. I one was to rotate it clockwise a little bit, it would line up perfectly.</p>
<p>wowwwwww</p>
<p>@ 1st problem What a simple problem to crush my brain. (B was 1 wasnt it?)</p>
<p>Y=2/3X+1? </p>
<p>@ 2nd problem How can you assume that it was rotated or that the triangle was 1/4 of the original square when you do not know the area of the second square and part of the triangle was clearly in the 2nd square?</p>
<p>Tilgaham-yeah, you just find the slope, and then plug in a point to get the intercept. Or run a regression on your calculator, that's what I did. I think the answer was 8/3?</p>
<p>No it's not x+s it's x-t+s</p>
<p>The question was:
If a person adds T books, then she has X number of books. Instead of adding T, she decides to add S. What is the expression</p>
<p>She added 5(t) and got 20(x). Instead of adding 5(t), she decides to add 3(s). So it becomes 20-5+3 = 18.</p>
<p>can someone post the updated answer list again? thanks.</p>
<p>b was 8/3.
For example, one of the points was (20, 16), so 20 = (2/3)(16) + b. Solve for b, so it is 8/3</p>
<p>as for the square, the second squares edges were at the center of the 1st square.</p>
<p>she has x books after she adds t books... if she doesnt add t books she has x-t books, which is the original # of books. so you add s to that to get the answer</p>
<p>x-t+s was the correct answer. iwaswalking has the question right ^^</p>
<p>Lets hope my CR and W scores make up for what looks to be a poor math score in my first sitting of SAT.</p>
<p>dont mean to be annoying...but...anyone know what the answer was to the question where g(x) is greater than f(x), had to do with intervals. i had 4 math sections. im trying to decide which one was experimental. im thinking it was the one after the grid-in, because they dont make the grid-in experimental right?</p>
<p>I believe i also got 16 for the 2 sq question...</p>
<p>I believe i found the area of the triangle (if you moved the side to fit the sq completely instead of the weird "polygonic" shape it was then you will get the height as 4 and the base as 4 and 4...</p>
<p>(4 x (4+4) ) / 2 = 4x8/2 = 32/2 = 16</p>
<p>and the experimental i believe would be section 6... we should all have the same experimental section #, not the same experimental but the # should be the same</p>
<p>dude it is so much easier than that tomackze. the corner of one square reached the center of the other square which means exactly 1/4th of the square was shaded in. 64/4= 16 </p>
<p>easy as pie.</p>
<p>Just make two new variables for the problem, C=# in collection beforehand and N=# after T is added to the collection</p>
<p>C+T=X,
C=X-T
C+S=N
N=X-T+S</p>
<p>How did you guys figure out the slope for the y=mx+b problem?</p>
<p>yea it s was 8/3</p>
<p>the overlapping squares one...i got 16...i guessed, b/c it looked like 1/4th of the smaller square was shaded (and since the corner of the larger square didnt touch the origin, i assumed it might even be a little less than 1/4th if the larger square was identical to the smaller). so yeah, 64/4= 16.</p>
<p>did anyone get the one about balloons "if this girl wants 2 or 3 red ballons, 2 or 3 yellow, two or three red, and 1 or 2 yellow, and wants a combination of ten, then how many combinations can she make?" (the numbers are wrong, but you get the gist of the answer). </p>
<p>how did you do it? i didnt answer it, b/c i didnt have the slightest clue.</p>
