<p>^ Did you have this question:</p>

<p>If x=2, then y=3.</p>

<p>When y=6, then which of the following must be true:</p>

<p>Then there were 3 roman numeral choices, forgot 2 of them but rememeber that one of them was x cannot equal 2</p>

64

<p>Wo wo guys, for the oval one, you guys got 1/2? Why did i get 1/4 O_O And the guy above me got 1?</p>

<p>@above, it was just the x cannot equal 2 option</p>

65

<p>I believe I got 1/4 for the ellipse one, i dont understand why x cannot be 2. I thought the answer was none of them because I pictured a a graph and obviously an x value can produce multiple y values</p>

66

<p>@above, no because, IF THEY gave x the value of 2, Y HAS TO BE GIVEN the value of 3, which it wasnt.</p>

<p>Y is the dependent variable. x is independent. The value of y is based on the value of x. If the value of x is 2, it clearly stated that y must be 3.</p>

<p>If the x value of 2 had multiple y values, it would fail the vertical line test D:</p>

67

<p>How did you remember all the math answers? O_o</p>

68

<p>Haha. I finished with like fifteen or twenty minutes left on all the sections so I just put them in my calculator. I knew it would be appreciated on CC :slight_smile: Do they all appear to be right?</p>

69

<p>^ yes a function would fail it but not a graph</p>

70

<p>I dont remember getting 1 for number 20
in section 3. I think it was 1/4.</p>

71

<p>@Novaray, so you’re saying “If x= 2, then y = [insert number here].” I dont think college board meant it that way.</p>

72

<p>@siddy, ya I think i am overthinking it lol, calc bc is messing with my mind. And yes I also did get 1/4 and I am pretty confident about that one</p>

73

<p>haha yeah in calc bc as well . didnt think too much of that problem tho</p>

74

<p>it didn’t specify that it had to be a function… so
it could be
x = 2 or any y = mx+b
I said “None”</p>

75

<p>ive never seen collegeboard pull something like that . The problem was straightforward and it was like in problems 1-10, so i highly doubt they wanted to trick us there.</p>

76

<p>Does anyone remember what the question was for Section one num 7 according to Greywolf’s post? I think i remember getting (-2,-2) as an answer for something not both positive two’s.</p>

77

<p>I dont recall wat question it was</p>

78

<p>I also got 200 for the poet problem.</p>

79

<p>I am positive the ellipse one was k=1. That’s a well-known formula. The (2,2) one referred to the point not on some line.</p>

80

<p>Im certain it is 1/4. It said that 2 segments were both cut in half. Therefore the new equation becomes (1/k(AB x CD)) in which AB and CD are both half of the original segments. If k = 1/4, then you get 4 times AB x CD which is correct. (2AB x 2CD = 4(ABxCD))</p>
