<p>Thanks melzideril but I meant all the questions on the test</p>
<p>@feminist
P.S. For primes I think option I was s+t+1. I got that that was the only one that could be prime.</p>
<p>@jermeylin12
I wish…</p>
<p>^ could you describe the prime question in more detail I don’t remember it</p>
<p>I don’t remember exactly but I remember that option II didn’t work for prime numbers 3 and 5 but it worked for prime numbers 5 and 7, as well as 7 and 11. Does anyone remember what number the dog question was?</p>
<p>@jeremylin r and s are both positive, prime numbers, which of these expressions could result in another prime number.
I. r+s+1
II. rs+1
III. rs+s</p>
<p>i put I only</p>
<p>Wasn’t 10 one of the answer choices for the prime question? And the dog was about 43</p>
<p>@jermeylin12
It was like if s and t are primes greater than 2, which of the following could be a prime number</p>
<p>Actually I might have put I only… my mind is so jumbled up right now.</p>
<p>I put none of the above cuz if s=3 and r=5 nothing woks</p>
<p>At this point, I’m just trying to remember random questions… if anyone remembers them in detail, could you repeat the question? Like does anyone remember 2x3 matrices one? I put answer choice C, don’t remember the exact numbers at all. Also, there was one that had something to do with 11x = 20y and another one that required finding the sum of the slopes of a triangle and the points were (0,0) (7,-1) (2,3)?</p>
<p>@syjkim35
i think for the slopes question it was 1/7
for the matrices one i think it was x+2y=6 when x=4
so i put y=1</p>
<p>The product of the slopes of the triangle was (1)(-1)(-1/4) = 1/4 I think.</p>
<p>@jermeylin12:
Are you thinking of the factors question, because the primes question had variable answer choices</p>
<p>It was 1/7, but you have general idea</p>
<p>or 1/7… what is wrong with my memory.</p>
<p>@feminist
it was 1<em>-1</em>-1/7 = 1/7 for product of slopes</p>
<p>what was the periodic function question you mentioned in your list? @melzideril</p>
<p>@syjkim35
For matrix addition problem, I got y=1, but I don’t remember if that was option C
I got 11/29 for the one where it was fraction in x and y =10, find a different fraction involving x and y</p>
<p>@feminist.<br>
You had a graph that repeated every 7 and you had to say what f(100) was</p>
