Answer 1

Jawaban :

25. 3

26. (4, 3)

Penjelasan dengan langkah-langkah :

25.

gambar diatas ↑

k = 6/2

k = 3

26.

P → (6, -2)

P' → (3, 5)

[a b]

P (x, y) -------> P' (x+a, y+b)

[a b]

P (6, -2) -------> P' (6+a, -2+b)

[a b]

P (x, y) -------> P' (x', y')

[a b]

P (6, -2) -------> P' (3, 5)

x' = x+a

3 = 6+a

3-6 = a

-3 = a

a = -3

y' = y+b

5 = -2+b

5+2 = b

7 = b

b = 7

Q → (7, -4)

[a b]

Q (x, y) -------> Q' (x+a, y+b)

[-3 7]

Q (7, -4) -------> Q' (7+(-3), -4+7)

[-3 7]

Q (7, -4) -------> Q' (7-3, -4+7)

[-3 7]

Q (7, -4) -------> Q' (4, 3)
