<p>Please someone explain this problem, I just dont understand how to solve it for some reason.</p>
<p>shahdin, the probelm went somethingh like thsi.</p>
<p>what is (x+y)^2, if xy=-10+a, and x^2 + y^2 = a ? it was something llike this. any way when you square x-y you get x^2 + 2xy + y^2, and then u substituate</p>
<p>one more thing the survey question on the consolidated list was a grid in and the 1080 average question was an MC. they’re in the wrong categories on the list.</p>
<p>only **** wrong so far is that 119 answer. *** was i thinking with 120… what are curve predictions?? people are sayin it was an easy test but it was controversial so u think medium curves?</p>
<p>Ahh I had 119 first, den I overtaught it and put 121. Thur goes my high 700’s :/</p>
<p>Can someone explain the
X^2 > 3/5 y^3 question?
I’m freaking out because I thought it was x^2 < 3/5 y^2!!!
I plugged in numbers and I was positive that X was going to be smaller!!!</p>
<p>Anyone remember the question where they gave you a picture of a coordinate grid with 3 points A, B, and C. The asked you which ones satisfied y > 3x-1. Ring a bell for anyone or no?</p>
<p>Please someone answer my question! I am freaking out</p>
<p>I rememberz!</p>
<p>protoslg you remember that question? The answer was A only right?</p>
<p>:):):):):):):)</p>
<p>Is it really x^2 > 3/5 y^2?
not x^2 < 3/5 y^2?
Please explain!</p>
<p>I’m going to repost this since I don’t know if my other comment made it (I was auto-logged out).
For the BRGY question, use the modulo operator. The modulo operator is only concerned with the remainder as opposed to the dividend.
B 1
R 2
G 3
Y 4/0</p>
<p>If the modulo comes out to 1, it’s Blue, 2, it’s Red, 3, it’s Green. If it divides evenly (remainder of 0 or 4) it’s Yellow. 119%4=3, so it’s Green.</p>

<p>the sign only changes if you multiply by a negative number, i think all you had to do was square it and then divide, and i think it said they were positive numbers.</p>
<p>that should be correct</p>

Do you remember the question by any chance?
I am wondering cuz I know I checked the answer by plugging in numbers.
Did you plug in numbers to chef the answer as well?</p>
<p>For the obtuse triangle whose answer was 10<x<14, could I have put an answer like 11.1? Or did the answer have to be an integer?</p>
<p>Londongentleman -
I think any value of x that satisfies 10<x<14 is fine, so yes, non-integral values are totally fine.</p>
<p>15 perimeter of triangle</p>
<p>can someone please tell me what question was this?</p>
<p>it was similar triangles</p>
