Tolong bantu mengerjakan soal matematika saya kak kelas 8 smp, soal ada di lampiran
Penjelasan dengan langkah-langkah:
1. f(x) = 5x + 12
f(5) = 5.5 + 12
f(5) = 25 + 12
f(5) = 37
4. (3, 0) (0,-4)
m = y2-y1/x2-x1
m = -4-0/0-3
m = -4/-3
m = 4/3
5. 4x-3y-12
-A/B = -4/-3 = 4/3
6. (-1, 4) (2,-1)
m = y2-y1/x2-x1
m = -1-4/2+1
m = -5/3
7. (-1, 2) (2, 8)
m = y2-y1/x2-x1
m = 8-2/2+1
m = 6/3
m = 2
8. (3, 6)
m = 2
y-y1 = m (x-x1)
y-6 = 2 (x-3)
y-6 = 2x - 6
y = 2x - 6 + 6
y = 2x
y - 2x = 0
Segitu dulu, tangan cape ngetik
