Average annual tuition and fees for in-state students at public four-year colleges in a given region are shown in the table for selected years and graphed as
ordered pairs of points, where x= 0 represents 2005, x= 1 represents 2006, and
so on, and f(x) represents the cost in dollars. Answer parts (a) and (b) below.

da freeck kinda math is this just drop out

step-by-step explanation:

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
