Question

tolong bantu dan jangan asal ​

Answer 1

Materi : SPtLDV

Gambar yang Terlampirkan

(1) 4x + 3y < 24

{ x < 6 , y < 8 }

Titik Potong Sumbu x [ y = 0 ]

4x + 3(0) < 24

4x < 24

[ x < 6 ]

Titik potong sumbu y [ x = 0 ]

4(0) + 3y < 24

3y < 24

[ y < 8 ]

(2) x - y ≥ 2

{ x ≥ 2 , y ≥ -2 }

Titik potong sumbu x [ y = 0 ]

x - 0 ≥ 2

[ x ≥ 2 ]

Titik potong sumbu y [ x = 0 ]

0 - y ≥ 2

-y ≥ 2

[ y ≥ -2 ]

(3) - 2x - 5y > 10

{ x > -5 , y > -2 }

Titik potong sumbu x [ y = 0 ]

- 2x - 5(0) > 10

- 2x > 10

[ x > -5 ]

Titik potong sumbu y [ x = 0 ]

- 2(0) - 5y > 10

- 5y > 10

[ y > -2 ]

Semoga bisa membantu
