1. What is the value for f(4) if f(x)=2x What is the Value of f(-5) if f(x)=20x
1. f(x) = 2x
ㅤf(4) = 2(4)
ㅤf(4) = 8 ✔️
2. f(x) = 20x
ㅤf(-5) = 20(-5)
ㅤf(-5) = -100 ✔️
Jawaban:
[tex]1). \: f(x) = 2x \\ f(4) = 2.4 \\ = 8 \\ 2). \: f(x) = 20x \\ f( - 5) = 20.( - 5) \\ = - 100[/tex]

[tex]x = 7[/tex]
5. if 3x - y = 12, What Is The Value Of 8x/2y ?
In your question, there are no more information about that linear eqution, so we can't find the real value for 8x/2y..
6. What is the value of x in 3(x-4) =-20
Kelas 7 Matematika
Bab Persamaan Linear
3 (x - 4) = -20
3x - 12 = -20
3x = -20 + 12
x = -8/3Jawaban :
3(x-4) = - 20
3x - 12 = - 20
3x = -20 + 12
3x = -8
x = -8/3
x = - 2 2/3
7. If x = 3 − √2, what is the value of x2 − 6x + 11?
Materi : Bentuk Akar dan Pangkat
( x = 3 - √2 )
x² - 6x + 11
= ( 3 - √2 )² - 6( 3 - √2 ) + 11
= ( 3 - √2 )( 3 - √2 ) + 6√2 - 18 + 11
= 9 - 6√2 + (√2)² + 6√2 - 7
= 9 + 2 - 7
= 9 - 5
= 4

maaf kalo salah
Penjelasan dengan langkah-langkah:
[tex] \frac{7}{7} \times \frac{7}{4} \\ = 1 \times \frac{7}{4} \\ = \frac{7}{4} = 1 \frac{3}{4} \\ \\ atau \\ \frac{7}{7} \times \frac{7}{4} \\ = \frac{49}{28} \\ = \frac{7}{4} = 1 \frac{3}{4} [/tex]
10. x+ 10%= 75,000 what is the value of x?
[tex] = 75000 \times \frac{10}{100} \\ = 7500 \\ x + 10\% = 75000 \\ x = 75000 - 10\% \\ x = 75000 - 7500 \\ x = 67500[/tex]
11. what is the value of x?
Jawaban:
x = 4
Penjelasan dengan langkah-langkah:
[tex] \frac{ {2}^{x + 2} + {2}^{x + 4} + {?}^{x + 6} }{128} = \frac{21}{2} [/tex]
[tex] {2}^{x + 2} + {2}^{x + 4} + {2}^{x + 6} = \frac{21}{2} \times 128[/tex]
[tex] {2}^{x + 2} + {2}^{x + 4} + {2}^{x + 6} = 1344[/tex]
[tex](1 + {2}^{2} + {2}^{4} ){2}^{x + 2} = 1344[/tex]
[tex](1 + 4 + 16) {2}^{x + 2} = 1344[/tex]
[tex]21 \times {2}^{ x + 2} = 1344[/tex]
[tex] {2}^{x + 2} = \frac{1344}{21} [/tex]
[tex] {2}^{x + 2} = 64[/tex]
[tex] {2}^{x + 2} = {2}^{6} [/tex]
[tex]x + 2 = 6[/tex]
[tex]x = 6 - 2[/tex]
[tex]x = 4[/tex]
jadi, nilai x adalah 4

nomor 19 + 5p = 24. nilai p = ?
→ 9 + 5p = 24
→ 5p = 24 – 9
→ 5p = 15
→ p = 15/5
→ p = 3nomor 24 + m = 3 x 2. nilai m = ?
→ 4 + m = 3 x 2
→ 4 x m = 6

18. If x – y = 9 and 10xy/5=15 . So, what is the value of x2+y2 …
Jawaban:
96
Penjelasan:
Diketahui x - y = 9 dan 10xy/5 = 15. Berdasarkan informasi tersebut, nilai 2xy = 15. Untuk memperoleh bentuk x² + y², lakukan operasi berikut:
x - y = 9
(x - y)² = 9²
x² + y² - 2xy = 81
x² + y² - 15 = 81
x² + y² = 96
The value of x² + y² is 96.
Semoga membantu :)
19. If f(x) = 2(3x - 5) when f(x) = 74, what is the value of x?
f(x) = 2(3x - 5)
f(x) = 74
value of x is = ....
f(x) = 2(3x - 5) = 74
6x - 10 = 74
6x = 74 + 10
6x = 84
x = 84 : 6
x = 14
so, the value of x is 1420. Look at the figure aboveWhat is the value of X?
Materi : Sudut
x = 180° - (55° + (180° - 83°))
x = 180° - (55° + 97°)
x = 180° - 152°
x = 28°
