Penyelesaian dari pertidakpersamaan nilai mutlak dari |3x − 2| + 2x − 5 ≤ 0 adalah….. tolong jawab kak plis bsk dikumpulkan
nilai mutlak |3x - 2| + 2x - 5 ≤ 0 |3x - 2| ≤ 5 - 2x (3x - 2)² - (5 - 2x)² ≤ 0 (3x - 2 + 5 - 2x)(3x - 2 - (5 - 2x)) ≤ 0 (x + 3)(5x - 7) ≤ 0 -3 ≤ x ≤ 7/5 syarat : 5 - 2x ≥ 0 2x ≤ 5 x ≤ 5/2 HP = {x| -3 ≤ x ≤ 7/5 , x ∈ R}
nilai mutlak
|3x – 2| + 2x – 5 ≤ 0
|3x – 2| ≤ 5 – 2x
(3x – 2)² – (5 – 2x)² ≤ 0
(3x – 2 + 5 – 2x)(3x – 2 – (5 – 2x)) ≤ 0
(x + 3)(5x – 7) ≤ 0
-3 ≤ x ≤ 7/5
syarat :
5 – 2x ≥ 0
2x ≤ 5
x ≤ 5/2
HP = {x| -3 ≤ x ≤ 7/5 , x ∈ R}

Jawaban: C. 404 Penjelasan dengan langkah-langkah: = a + (n-1)b = 8 + ( 100-1)4 = 8 + (99)4 = 8 + 396 = 404
Jawaban:
C. 404
Penjelasan dengan langkah-langkah:
= a + (n-1)b
= 8 + ( 100-1)4
= 8 + (99)4
= 8 + 396
= 404

Persamaan Trigonometri
cos 3x = sin x
cos 3x = cos (90 – x)°
3x = 90° – x + k.360°
3x + x = 90° + k.360°
4x = π/2 + k.2π
x = π/8 + k.π/2 … (1)
cos 3x = sin x
cos 3x = cos (270 + x)°
3x = 270° + x + k.360°
3x – x = 270° + k.360°
2x = 3π/2 + k.2π
x = 3π/4 + k.π … (2)
k bilangan bulat
Interval [0 , 2π]
Substitusikan k ke persamaan (1) dan (2)
k = 0
x = π/8 atau x = 3π/4
k = 1
x = 5π/8 atau x = 7π/4
k = 2
x = 9π/8 atau x = 11π/4
k = 3
x = 13π/8
HP = {π/8, 5π/8, 3π/4, 9π/8, 13π/8, 7π/4}
