Question

Persamaan bayangan garis x+2y =4 jika ditranslasikan oleh t = (1 2) adalah

Answer 1

Verified answer

Dalam bentuk matriks ya
(x',y')=(x, y)+(a, b)
(x,y)=(x',y')-(a,b)
= (x',y')-(1,2)
= (x'-1,y'-2)
x+2y=4
x+2y=4
(x'-1)+2(y'-2)=4
x'-1+2y'-4=4
x'+2y'-5=4
jadi x+2y=9
maaf ya jika ada kesalahan

Answer 2

Verified answer

Jawab

(x,y) + T(1,2) = (x',y')
x = x' - 1
y = y' - 2

(x ) + 2(y) = 4
(x' -1) + 2(y' -2) = 4
x - 1 + 2y - 4 = 4
x + 2y - 5= 4
x + 2y = 9
