A. x = 4
B. x = -4
C. x = 4 atau x= -4
D. x ≤ 4
E. x >_ 4
Nilai x yang memenuhi |x-4| = |x| -4 adalah
Jawaban Terkonfirmasi
|x – 4| = |x| – 4
|x – 4| – |x| = -4
x – 4 – x = -4, x – 4 ≥ 0, x ≥ 0
– (x – 4) – x = -4, x – 4 < 0, x ≥ 0
x – 4 – (-x) = -4, x – 4 ≥ 0, x < 0
– (x – 4) – (-x) = -4, x – 4 < 0, x < 0
x ∈ R, x ≥ 4, x ≥ 0
x = 4, x < 4, x ≥ 0
x = 0, x ≥ 4, x < 0
x ∈ Ø, x < 4, x < 0
x ∈ R, x ∈ [4, + ∞)
x = 4, x ∈ [0, 4)
x = 0, x ∈ Ø
x ∈ Ø, x ∈ (-∞, 0)
x ∈ [4, + ∞)
x ∈ Ø
x ∈ Ø
x ∈ Ø
x ∈ [4, + ∞)
Jawaban A. x = 4
