Question

Tolong bantu di jawab dong no 35 dan 36

Answer 1

35) (6,3) ditranslasi (2, -3) = (6+2, 3+(-3)) = (8,0)
(8,0) dtranslasi (-1, 4) = (8+(-1), 0+4) = (7,4)

36) (-1,4) ditranslasi (-5, 2) = (-1+(-5), 4+2) = (-6, 6)
(-6, 6) didilatasi pusat (9,-3) faktor skala 3
Rumus (x,y) didilatasi pusat (a,b) faktor skala k
(k(x - a) + a, k(y - b) + b)
= (1/3 (-6 - 9) + 9, 1/3 (6 - (-3)) + (-3))
= (1/3 (-15) + 9, 1/3 (9) - 3)
= (4, 0)
