<p>Does anyone remember the problem that was: If f(x)=x+1, what is the value of f(x)-1? I think I put x, but then I thought I saw something on the boards with a different answer. Unless I'm remembering the problem incorrectly...</p>
<p>ur right, the answer was x</p>
<p>Can anyone reproduce the car question for me? I don't really remember if it was mult-choice or grid-in, but if it was mult-choice can anyone reproduce the options as well? Both 80 and 28 sound familiar and I don't remember what I put so maybe I can just do it again.<br>
Another one I'm not sure of is a grid-in one. I don't remember the question but I remember putting 2880, and I see some people have 2400 posted earlier in the thread.
Anyway, if those two were the only ones I got wrong what could my score be? What if only one was wrong?</p>
<p>the 2400 one was like:</p>
<p>the ratio of children to adults was 1:4 at a party. If there were 480 children, how many people were at the party total?</p>
<p>480 * 4 = 1920 + 480 = 2400</p>
<p>the answer was x for that one about the functions. So have we discussed all the math questions (other than the ones at the beginning), safe to say my score stands at a 74.</p>
<p>what was the answer for an angle one was 2 and the other one was 27 i believe how did u have to find the other angle? i got so confused on that question cause i thought there wasnt enough information for some reason cause it didnt specifie what kind of triangle it was</p>
<p>.:Indian:.</p>
<p>oh crap did u have to add the children too? i thought it asked only for adults not the kids included</p>
<p>snuggle, was it the one where you had to say one possible angle for two already given angles? the grid-in question</p>
<p>BTW here's last year's maht curve
80 - 38
77 - 37
74 - 36
72 - 35
70 - 34</p>
<p>yeah snuggle u had to add the adults too</p>
<p>hey whats a -6 in CR PSAT, -4 Math and hopefully no more than -2 or 3 on writing..... is tehre no way it could be semi finalist =(</p>
<p>(x-y)(x^2+y^2)=0 <for this one wouldn't it be:
x^3 - y^3 = 0
x^3 = y^3 <<I think it was choice E or something.<br>
I don't even remember x^2 = y^2 being an answer choice.</p>
<p>"anyone get x^2 = y^2 for that last question of first math section?"</p>
<p>I put x=y but it was pure guess since I was almost out of time and wanted to go back to answer the artist submitting their painting question (got 7 for that). It seemed logical. I also remember putting down 80, 2400, .25, 52.5 for the student-produced.</p>
<p>Okay, this is about the PSAT (but not math). What did you all get for the gorilla reading question that said something like "how does the river act as a cultural barrier?" I was stuck between 2 answers: "It prevent them from exploring different habitats" and "It prevents them from learning technical skills from other gorillas"</p>
<p>The former seemed more sensible, but I chose the latter, because in my experience, I tend to be surprised by specificness of right answers.</p>
<p>it was definitely x^2 = y^2 ...letter c, i believe?</p>
<p>naidu90 yes i figured it out i had to do square root after not divide by two to find the angle i feel so dumb now small mistakes ugh</p>
<p>Was it just me or was the whole PSAT much easier this year... XD or maybe I just learned alot over 1 year.</p>
<p>For the sunday one I just counted... Wrote mon-sun a few times on my paper and counted them up XD Mathematically sound I know.</p>
<p>for the (x+y)(x+y)(x-y)=0 would x=y work because if it is a - number they still go to zero in (x-y).</p>
<p>For example x=-1</p>
<p>-1-(-1)=
-1+1=0</p>
<p>Now that we have 0 won't the product be 0. Help me understand!</p>
<p>any forums on the writing/critical reading section</p>
<p>Or how about that question that was like- susie's coworkers were surprised at her mean comment or something. in the choices was like- repartee and soliloque and some d word I didn't know...</p>
<p>x^2=y^2 is the only answer choice that is true in ALL cases.</p>
<p>For example, the answer choice x=y bears no fruit if x=2 and y=-2, because (x+y)(x^2-y^2) still equals in 0 in this case. Meanwhile, x=-y does not always work, because if x=2 and y=2, then, again, the above expression would equal zero. The only answer choice that encompasses all possible values of x and y, therefore, is x^2=y^2.</p>
<p>The answer to the question posed in comment 138 is "diatribe."</p>
<p>score. diatribe was what I marked. thank you. That really confusing one is on the saturday? XD I don't even remember it. Which means that I probably misread the question, assumed it was easy, and got it wrong. :/ Eh- what are you going to do? I hope I did well on the english part though.</p>
