Pretest RO (2)

maksimumkan Z = 2×1 + 3×2

terhadap Kendala-kendala

1. 5×1 + 6×2 <= 60

2. x1 + x2 <= 16

3. x1 <= 10

4. x2 <= 6

5. x, x2 >= 0

Jawabannya

1.ubah semua tanda ke dalam bentuk =

5×1 + 6×2 = 60

x1 + x2 = 16

x1 = 10

x2 = 6

2. Tentukan titik potong untuk x1 dan x2

jika x1 = 0 ,

5×1 + 6×2 = 60

5(0) + 6×2 = 60

x2 = 10

jika x2 = 0

5×1 + 6(0) = 60

x2 = 12, titik (x2,x1) = (12,0) dan (0,10)

II fungsi kendala 2

x1 + x2 = 16

jika x1 = 0, x2 = 16

jika x2 = 0, x1 = 16

titik(x2,x1) = (16,0) dan (0,16)

Sisanya Gamar Grafik fungsinya
