9. 2. Given a quadratic equation 2(x-5)²= 4(x + 7).(a) express the equation in general form, that is ax²+bx+c=0​


2(x - 5)² = 4(x + 7)

2(x² - 10x + 25) = 4x + 28

2x² - 20x + 50 = 4x + 28

2x² - 20x + 50 - 4x - 28 = 0

2x² - 24x + 22 = 0

x² - 12x + 11 = 0

Jawab:

2(x-5)² = 4(x+7)

2(x²-10x+25) - 4(x+7)=0

2x²-20x+50-4x-28=0

2x²-24x+22=0

so in general from is

2x²-24x+22=0


10. . Is the following equation a linear equation of 2 variables. x - y = -4 * a.yes b.no


menurut saya jawaban nya A karena ada x dan y


11. persamaan 2 x tambah 5 = 7 equivalent dengan


2x + 5 = 7
<=> 2x = 2
<=> x = 12x + 5 = 7
2x = 7-5
2x = 2
x = 1

12. What is the missing fraction? 16 : 8 is equivalent to ... of 16 *​


Jawab:1/8

Penjelasan dengan langkah-langkah:

16:8=16n

n=2/16=1/8


13. which of the fractions below is the simplest equivalent fraction of 10/25


10/25
= 10:5/25:5
= 2/5

14. find the equation of the straight line which passes through the point (-2,4) and is parallel to the line y=2x +5.


y = 2x + 5
m = 2

y - b = m(x - a)
y - 4 = 2(x -(-2))
y - 4 = 2(x + 2)
y - 4 = 2x + 4
y = 2x + 4 + 4
y = 2x + 8

15. |3x + 5) = 8. Find all values of x which make this equation true.


Jawaban:

1, -13/3

Penjelasan dengan langkah-langkah:

|3x + 5| = 8

if 3x + 5 positive:

3x + 5 = 8

3x = 8 - 5 = 3

Hence x = 1

if 3x + 5 negative:

-3x - 5 = 8

-3x = 8 + 5 = 13

Hence x = -13/3


16. find the equation of the circle whose radius is 5 which touches the circle x² + y² - 2x -4x -20 = 0​


Penjelasan dengan langkah-langkah:

x² + y² - 2x -4y -20 = 0

cari titik pusatnya dulu

x = –(–2)/2 = 1

y = –(–4)/2 = 2

jadi pusatnya (1, 2)

dengan r=5

kita cari titik potongnya

dengan :

(a+1)/2 = 5

a + 1 = 2(5)

a = 10-1

a = 9

(b+2)/2 = 5

b+2 = 2(5)

b = 10-2

b = 8

Persamaannya menjadi :

(x - a)² + (y - b)² = r²

(x - 9)² + (y - 8)² = 5²

x² - 18x + y² - 16y + (-9)² + (-8)² - 5² = 0

x² + y² - 18x - 16y + 81 + 64 - 25 = 0

x² + y² - 18x - 16y + 120 = 0

17. An equation is given below. 4(x - 7) = 0.3(x + 2) + 2.11 The solution to the equation is A. 8.3 B. 8.7 C. 3 D. -3


Jawaban:

4.53

Penjelasan dengan langkah-langkah:

4x - 14 = 0.3x + 0.6 + 2.11

3.7 x = 16.76

x = 4.53


18. the value of x for equation 35x=5 is?​


Penjelasan dengan langkah-langkah:
