Penjelasan dengan langkah-langkah:
nilai mutlak
soal
1 ≤ |x - 2| ≤ 4
|x-2| ≤ 4 atau |x-2| ≥1
i) |x-2| ≤ 4
- 4 ≤x - 2 ≤ 4
-2 ≤ x ≤ 6
ii) |x- 2| ≥ 1
x- 2 ≥ 1 atau x - 2 ≤ -1
x ≥ 3 atau x ≤ 1
HP { -2 ≤ x ≤ 6 } dan { x ≥ 3 atau x ≤ 1 }
HP x = {-2 ≤ x ≤ 1 atau 3 ≤ x ≤ 6 }
Use trait :
a < f(x) < b
-b<f(x)<-a
1 ≤ | x - 2 | ≤ 4
1 ≤ x - 2 ≤ 4
3 ≤ x ≤ 6
or
- 4 ≤ x - 2 ≤ -1
- 2 ≤ x ≤ 1

x + 3 = 8/2
x = 4 - 3
x = 1
13. factorise and solve each of the following equations. 10x² - 5x - 5 = 0
Penjelasan dengan langkah-langkah:
penyelesaiannya
x =-1/2 atau x = 1
Jawab:
x = -1/2 atau x = 1
Penjelasan dengan langkah-langkah:
10x² - 5x - 5 = 0 (bagi kedua ruas dengan 5)
2x² - x - 1 = 0
(2x + 1)(x - 1) = 0
maka 2x + 1 = 0 atau x - 1 = 0
Jika 2x + 1 = 0, maka 2x = -1, x = -1/2
Jika x - 1 = 0 maka x = 1
Jadi, x = -1/2 atau x = 1
14. the frations which has value equivalent to 12 1/2 persen to

15. Use the substitution method to solve the following pairs of simultaneous linear equations A)5X + 2y = -1 X - 3y = -7
~SPLDV
5x + 2y = -1 .......... 1)
x - 3y = -7 → x = 3y - 7 ...... 2)
Substitute The sec . Eq to The First Eq :
5x + 2y = -1
15y - 35 + 2y = -1
17y = 34
y = 2
With the same way , substitute the Value of 'y' to the sec . eq :
so we get ...
x = 3y - 7
x = -1
SC = {-1 , 2}
