<p>reflected across y = 3 was 4 right? or was it reflected over y = 4 is 5?</p>

<p>reflected over y = 4 is 5</p>

<p>how do you know if it is experimental section</p>

<p>@Ge231Fb- It was y=4 is 5 or something like that I don’t remember the question that well</p>

<p>wait it wasnt (6,8) with the circle one?
it was (5,5) ?</p>

<p>@hotdog57- the answer was (5,5)</p>

<p>it was (6,8)
thanks kk and totalderiv</p>

<p>edit:
i mean (6,8) worked, sorry. spacing out. the answer was (5,5)</p>

<p>dammitttttttttt</p>

<p>formula for a circle is x^2 + y^2 = r^2
r = 10
so x^2 + y^2 = 100
(6,8) works, (5,5) does not</p>

<p>Anyone remember the one with the function that asked for a point on the perpendicular? The choices were like (3/4,-1) and things like those.</p>

<p>Also the one either right after or before it with the answer choices 9sqroot 2 or 10aqroot 2?</p>

<p>so far:
(9,10) was the y= a(x-5)^2 + b
and x+y-z is -50
reflected over y = 4 is 5
potatoes 1/4
9:10
50-50 so answer is 0
sqroot 136
72pi
ap<ac</p>

<p>free response:
9,
7
1320
2200
3k/17 has to be 17
3x + 4(x) = 40, 7x = 40, x = 40/7
add guys</p>

<p>jcold9. i believe it was (-3/4,1) and i already said it was 9root2</p>

<p>it was -3/4,1</p>

<p>“i believe it was (-3/4,1) and i already said it was 9root2”</p>

<p>I got the same answers for these two</p>

<p>Wait you guys had the 3x + 4y = 40 as a free response? And what is the 1320 from?</p>

<p>1320 is the what is one possible volume for the rectangular solid or something one. like 3rd to last question</p>

<p>1320 was for the volume one.
it said there was a rectangular prism with one side with area 120 and one with area 110. what is a possible volume. it was a grid-in.
i said 1320. (10<em>12</em>11)</p>

<p>@totalderiv area of one side of rect. prism is 120, area of another side of same rect. prism is 110, what is volume</p>

<p>i don’t know if this was asked already, but the one about the ratio of squares, was it 4:9 for area? and how many 4 digit # greater than 4000 contain 2,4,6 and 8? for the that was like the ticks are evenly spaced, what is the value of x? what did yall put? I put 2 even though I know that was wrong…</p>

<p>i said 4:9 for area and 24 for number of 4 digit nums</p>
