I'm sorry its not free points this time ;-; I genuinely gotta question. 15 points tho so thats nice right?
State University is planning a tuition raise. The Dean of Admissions suggests that they increase tuition by $10\%$ each year for the next two years. The Provost suggests that each year they instead increase the tuition by $30\%$ of the amount of the tuition above $\$10{,}000$.
So, for example, if the tuition now is $\$25{,}000$, the Dean of Admissions is suggesting a $\$2{,}500$ increase in the first year. Meanwhile, the Provost is suggesting a $\$4{,}500$ increase (since the current tuition is $\$15{,}000$ more than $\$10{,}000$, and $30\%$ of $\$15{,}000$ is $\$4{,}500$).
The Treasurer points out that the tuition two years from now (after two annual increases) will be the same under either the Dean's plan or the Provost's plan. What is the tuition right now? (Assume the tuition is not $0$; State University is not free!)

-1/2 +2

step-by-step explanation:

3; 9 is 8 to -4

step-by-step explanation:

yes

step-by-step explanation:

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'.
