(2(2) – 1) + (2(3) – 1) + (2(4) – 1)

= (4 – 1) + (6 – 1) + (8 – 1)

= 3 + 5 + 7

= 8 + 7

= 15

f(x) = 3x – 2
g(x) = 4x + 1

f(1) + g(1) = …​

Matematika, Sekolah Menengah Atas

Penjelasan dengan langkah-langkah:

= f(1) + g(1)

= 3(1) – 2 + 4(1) + 1

= 3 – 2 + 4 + 1

= 1 + 5

= 6

f(x) = 3x – 2

g(x) = 4x + 1

f(1) + g(1)

= [3(1) – 2] + [4(1) + 1]

= [3 – 2] + [4 + 1]

= 1 + 5

= 6

tentukan nilai x yang memenuni
​

Matematika, Sekolah Menengah Atas

3/x + 1/2 = 5/8

3/x = 5/8 – 1/2

3/x = 5/8 – 4/8

3/x = 1/8

x = 24

3/24 + 1/2

= 1/8 + 1/2

= 1/8 + 4/8

= 5/8 [ Terbukti ]

⅛ + ¼ × 2 = …​

Matematika, Sekolah Menengah Atas

1/8 + 1/4 × 2

= 1/8 + 2/4

= 1/8 + 1/2

= 1/8 + 4/8

= 5/8

= 0,625
