<p>Why was the one with divisible by 3 I and II?i got only I</p>
<p>@s2aeca are you talking about this problem:</p>
<p>7(x+y+z) = 49p. x+z equals 5. For what value of y does p equal 1?</p>
<p>To s2aeca: I don’t remember that one either.</p>
<p>To everyone:
For the question about the graph shifted to the left two units I got -4, or A.
For the question 7(x+y+z) = 49P and P = 1 and x + z = 2 I found that y = 5.</p>
<p>Oh nooo, I missed the one that was 50pi-96. I forgot to divide by 2. Not even one of the hard ones, that’s just rough.</p>
<p>For the 30rad3 one can someone tell me what the question was? i dont remember that answer.</p>
<p>for those who got 10 for k, how did you? i got 2.5</p>
<p>texas one, it said at least 5, which means there can be 5, which is false (i think). NC is from .75-.8 .75x5=3.75 (or .8x5=4)
3.75+10.75 =/= 14.9
4+10.75 =/= 14.9</p>
<p>@SAT100 I m sure X +Z was 2 … no i got the answer right for that 1</p>
<p>No there was something like question 14, 20 min section i think? lefthanded side</p>
<p>something median … someone save me</p>
<p>Okay, on the one regarding the number of points in a triangle:</p>
<p>Was it not asking for the number of points INSIDE the triangle? If it was, it was 4. You wouldn’t count the origin.</p>
<p>If it asked for the points the triangle took up, it would be 7.</p>
<p>And does anyone know how generous a curve normally is?(points-wise)</p>
<p>@Lolol1
I clearly remember the question asking for the points “in the interior of the triangle”.</p>
<p>@Overide, yup, got both.</p>
<p>The 30rad3 was the question where there were two adjacent triangles. I think that one side was 15, the other was 60, and an angle was 120. There were a few right angles in the diagram too. It wanted to know the length of the side on the far right.</p>
<p>Okay, 14.9 - 10.75 = 4.15</p>
<p>NC < 1million, so that means other states also have to be <1million
so assume each state had 999,998, and NC had 999,999</p>
<p>4 x 999,998(has to be less than NC) would be 3.999992million =/= 4.15million, so ATLEAST 5 states had to make up 4.15 million, making the third statement correct.</p>
<p>I got 10 for the last gridded answer and I see some other people did too. Frankly I had no idea what I was doing and kind of stumbled through that problem. How was that one supposed to be done?</p>
<p>@Lolol1, YES 4 points is correct. Any points on the triangle’s sides or vertices do NOT count.</p>
<p>@Auxiliatrix, what was the question, I don’t remember.</p>
<p>It was the one with f(x)= root25x and f(4x) = k*rootx. I think you had to find k although I don’t quite remember.</p>
<p>@auxiliatrix</p>
<p>Well g(x) = Sq.rt(25x) and g(4x)= k sq.rt(x).</p>
<p>So basically, you just multiply 25 by 4 (because you substitute the x for 4x) and you get g(4x)= sq.rt (100x). Just simplify the problem from here to: Sq.rt(100) * sq.rt(x).
Sq.rt of 100 is 10, so 10 sq.rt(x).</p>
<p>Of course I didn’t do this during the test. I saw the question and panicked because it seemed difficult. In the end, I solved it by just plugging in some numbers and guessing.</p>
<p>plug in 4x into sqrt25x</p>
<p>which would make it sqrt(25(4x))
yields to sqrt(100x)
yields to 10sqrt(x)</p>
<p>so it would be 10</p>
<p>I plugged in semi-random numbers and guessed too. I didn’t get to check it though and the entire thing was done in 3 minutes of panic right at the end. I figured that was not how it was actually supposed to be done. Thank you for explaining!</p>
<p>and does anyone have an idea on how the curve is going to be like?</p>
<p>and np</p>
<p>@Lolol1 I think it’s going to be extremely steep. These questions were really easy.</p>
