Examples: 4 check ups / 2 people, 10 dogs / 3 people, 7 computer / 10 people

Each of these shares a common thing. The numerator and denominator have different units.

Well rates are actually comparisons of quantities showing a pattern, (just comparing two quantities would be a ratio :P), and UNIT rates are how much a quantity's supplied per single quantity.
Example; (regular rates), 230/5, 322/7, 414/9.
Well, the unit rate for those 3 examples would be 46/1, because in order to figure how much is provided per unit, you would take one of the examples, and divide the top by the bottom, so like you could take 322 and divide it by 7 to get 46, so that would mean it's 46 per unit. They are all in common because they have the same unit rate, and increased by 2. (230/5), (322/7), and (414/9- you add 2 to 5 to get 7, and 2 to 7 to get 9.)

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.

therefore, the correct answer is d.

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'.
