a.18 x + 6 y ≥ 24

b.2x + y < 6 ​

PertiDAksamaan  Linier
Daerah HP ( daerah yg di arsir)

 

 

Penjelasan dengan langkah-langkah:

 

tentukan  daerah HP (DHP) dari

a.  18 x + 6y ≥  24
buat  garis  18x   + 6y = 24
x= 0, y = 4 –> A(0,4)
y =0 , x= 24/18 =4/3 —> B(4/3 , 0)

DHP untuk   18 x + 6y ≥  24, adalah :
arsir dari AB menjauhi (0,0)
lihat gambar (i)

 

b. 2x + y < 6
buat gais 2 x+ y = 6
x =0, y = 6 –> C(0,6)
y = 0 , x= 3 –> D(3,0)

DHP  untuk 2x + y < 6, , adalah
arsir dari AC(putus-putus) mendekati (0,0)
lihat gambar (ii)

 

a.18 x + 6 y ≥ 24
