Question

Dik : p1 = 25.000 q1=1500
p2 = 20.000 q2=1000
ditanyakan Fungsi ???

Answer 1

P1 = 25.000 Q1 = 1500
P2 = 20.000 Q2 = 1000

biar lebih gampang Semua dibagi 1000 jd
p1 = 25 q1 = 1,5
p2 = 20 q2 = 1

dtny fungsi???
P-P1 Q-Q1
--- = ----
P2-P1 Q2-Q1

P-5 Q-1,5
--- = ----
20-25 1- 1,5

P-5 Q-1,5
---- = -----
-5 - 0,5

-1/2P + 2 1/2 = -5Q + 7 1/2
-1/2P + 5Q = 7 1/2 - 2 1/2
-1/2P + 5Q = 15/2 - 5/2
-1/2P + 5Q = 15-5 / 2
-1/2P + 5Q = 5

jd fungsinya adl -1/2P + 5Q = 5
