<p>the x + y one was A. 10</p>
<p>4 for the candy and paradigm are what I had. For the candy the guy lost 1 and gained three for a net gain of three, and the girl vis versa. I'm pretty sure it was four. Anyone with further insight?</p>
<p>you mean (x+y)^2 - (x-y)^2=84 </p>
<p>yes! the answer is ten ..... x=7 y=3
100-16=84</p>
<p>what was the answer to something like f(x)= SQRT 2x and if f(c)= 4 what is c. I put 8 because SQRT(2*8)= 4</p>
<p>I think I got paradigm too.</p>
<p>woah
i thought you set it equal
sqrt (2x) = 4
square both sides
2x = 16
x = 8</p>
<p>yes, the answer was 8 .....</p>
<p>What if we expressed our answer as a decimal on the one that was 1/2? I put .5</p>
<p>:S</p>
<p>I got eight...it seemed ay too easy though.</p>
<p>does anyone remember journalism answers??</p>
<p>decimals are fine</p>
<p>Corey,</p>
<p>A decimal or a fraction is fine.</p>
<p>i put .5 as well Corey - that is fine</p>
<p>Decimal conversions of fractions are accepted.</p>
<p>So 1/2 and .5 are both acceptable</p>
<p>I'm hoping the equilibrium for National Semi FAnalist will be low, because this Psat was pretty hard compared to ones I've done in the past.</p>
<p>sar ... that was the one interesting passage on this whole exam! Why, you have a question?</p>
<p>I think you wrongly used "equilibrium" in that context :-p</p>
<p>yeah, second question on that, what is passage 2 about, do you remember what you put? and the last one talking about both</p>
<p>the journalism questions were nasty and lame. I don't know if I got them right or not.</p>
<p>really?! I thought that was the easiest part ..... sorry sar, I dont exactly remember the questions - come to think of it... I remeber one of the answers being "hopeful" - that was one of the tone questions .......</p>
