Question

Sistem persamaan linear dan kuadrat dua variabel.,
dengan garis parabola..(kalau ada gambarnya..,silahkan masukkan )
x - y = 3
(x - 6)2 = 3(y + 3 )

Answer 1

X - y = 3 <===> y = x - 3

(x - 6)² = 3(y + 3)
x² - 12x + 36 = 3y + 9
x² - 12x - 3y + 27 = 0
subs y = x - 3
x² - 12x - 3(x - 3) + 27 = 0
x² - 12x - 3x + 9 + 27 = 0
x² - 15x + 36 = 0
(x - 3)(x - 12) = 0
x = 3 atau x = 12

x = 3
y = x - 3
y = 3 - 3 = 0 tipot (3,0)

x = 12
y = x - 3
y = 12 - 3 = 9  tipot (12,9)
