Question

Tolong jawabkan yang nomor 13 please sama caranya

Answer 1

Koordinat garis = (0, 12) dan (6, 0)

persamaan garis :

y - y1 = x - x1
y2 - y1  x2-x1

y - 12 = x - 0
0 - 12     6-0


y - 12 = x
  - 12     6

6y - 72 = -12x
6y = -12x + 72
y = -2x + 12
f (x) = -2x + 12
f (p) = 6

-2p + 12 = 6
-2p = 6 - 12
-2p = -6
-p = -6/2
-p = -3
p = 3
