Romain knows the following information about the 323232 classes he took in high school:
He studied for but did not pass 333 classes.
He passed 272727 classes in total.
He studied for 262626 classes in total.
Can you help Romain organize the results into a two-way frequency table?

studies and passed: 26

did not study and passes: 1

did not pass and study: 3

did not pass and did not study: 2

Step-by-step explanation:

in total he had 32 classes. if he studied for 27 in total, he must have not studied for 5 because 27+5 is 32. He passed and studied for 26 so he didnt study and passed one which equals 27. He studied but sis not pass for 3 classes and did not study and did not pass for 2. that gives you 5. 5+ 27=32.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
