Each number in the list below can be paired with a different number in the same list to make an integer product except for one number. What is the letter corresponding to the one exception? A. $\sqrt{40}$
B. $\sqrt{54}$
C. $\sqrt{60}$
D. $\sqrt{90}$
E. $\sqrt{96}$
F. $\sqrt{120}$
G. $\sqrt{135}$

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)

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
