You need to dilute your sample 1:10 with NaCl. If you have 1 ml of sample left but want to save half for a different test. How much sample would you use? How much NaCl would you use?

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)

answer: none of these answers are correct only the second half is

step-by-step explanation:

answer: can you show the options ?

step-by-step explanation:

wow ok so the answer is 1k or just k

because of combining like terms xd
