За +ь – с
За +ь – с
В
Ос
За +ь – с
За нь = -с
За +ь – с
а — 3b = -с
За +ь — — с
а + 3 = -с

step-by-step explanation:

i think you should think about the question and not look online.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
