Question

diketahui f(x) = 3x - 5 jika f(k) = 7 tentukan nilai k​

Answer 1

Jawaban:

K = 4

Penjelasan dengan langkah-langkah:

_____________________________

f(x) = 3x - 5

f(k) = 7

k = ?

7 = 3k - 5

- 3k = - 5 - 7

- 3k = - 12

k = - 12 ÷ (- 3)

k = 4

Answer 2

Diketahui:

f(x) = 3x - 5

f(k) = 7

Ditanyakan:

Nilai k = __?

Penyelesaian:

f(x) = 3x - 5

f(k) = 3k - 5

ㅤ7 = 3k - 5

3k = 7 + 5

3k = 12

ㅤk = ¹²/₃

ㅤk = 4

∴ Jadi, nilai k adalah 4.
