1. 1. f(x) = 3x - 5. If the output is 31, what is the input? 2. f(x) = 7(x-4) If the output is 49, what is the input? 3. f(x) = 2x + 8 Find the value of x when f(x) = 14 4. f(x) = 3(2x + 4) Find the value of x when f(x) = 42 5. f(x) = 2x - 3 Find the value f(3x - 5)
1. x = 12
Cara:
31 = 3x – 5
31 + 5 = 3x
36 = 3x
x = 12
2. x = 11
Cara:
49 = 7(x – 4)
49 = 7x – 28
49 + 28 = 7x
77 = 7x
x = 11
3. x = 3
Cara:
14 = 2x + 8
14 – 8 = 2x
6 = 2x
x = 3
4. x = 5
Cara:
42 = 3(2x + 4)
42 = 6x + 12
42 – 12 = 6x
30 = 6x
x = 5
5. f(3x – 5) = 6x – 13
Cara:
f(x) = 2x – 3
f(3x – 5) = 2(3x – 5) – 3
f(3x – 5) = 6x – 10 – 3
f(3x – 5) = 6x – 13
2. In the function, multiply by 3 and add 8, what is the output if the input is 4?
Penjelasan dengan langkah-langkah:
the function is:
f(x) = 3x+8
x=4
=> f(4) = 3(4)+8 = 12+8
= 20
the output is 20
goodluck
x=4
f (4)= 3×+8
f (4)=3(4)+8=12+8
=20

13. int x, y, z, w; x = scanf(“%d %d %d”, &y, &z, &w); A. What happen if input was 2 integer values from the keyboard? B. What is x value if 3 character values given as the input?
Jawaban & Penjelasan:
Dari serpihan kode diatas, satu-satunya perbedaan ketika mengimput dua nilai atau tiga nilai dalam input adalah, ketika kita memasukan 2 nilai tombol "Enter" tidak menjalankan programnya namun akan memberikan garis baru. Jadi mau inputan dua atau bahkan satu nilai, programnya tidak akan memberikan output kecuali kita memasukan tiga nilai kedalamnya.
Seperti contoh dari Screenshot Hasil Coding yang saya lampirkan. Disini saya mencoba untuk hanya memasukan dua nilai, namun saya harus memasukan nilai ketiga untuk mendapatkan output dari x.

15. What is the process of accepting input data from a source other than the keyboard and sending output data to a destination other than the display device
The process to accpeting input from a source to other keyboard is redirection.
Penjelasan:
Ada dua jenis pengalihan: penekanan output dan penekanan input. Selain itu, konsol Linux memiliki beberapa input dan output standar yang perlu Anda ketahui. Pengalihan input sering digunakan untuk program yang membutuhkan input panjang. Misalnya, jika administrator database MySQL Anda ingin mengimpor file backup.sql ke database Anda, Anda dapat menggunakan perintah input direction. Simbol pengalihan input adalah & lt ;. Ada banyak contoh lain, tetapi itu sepenuhnya tergantung pada kreativitas Anda sendiri. Misalnya, berikut ini adalah kombinasi dari perintah pipelined dan transfer. Misalnya, dapatkan 20 baris pertama dari manual ifconfig dan simpan di file ifconfig.txt. Contoh berikut menyimpan manual ifconfig di file man_ifconfig.txt. Sehingga proses tersebut merupakan proses redirection.

19. The output power of an engine is 600 kW. if the efficiency of the engine is 75%. Determine the power input .... kW
efisiensi = (keluaran÷masukan) x 100%
75 % = (600 ÷ masukan) x 100%
0,75 = 600 ÷ masukan
masukan = 600 ÷ 0,75 = 800 kW
20. Rumus produktivitas adalah A ( input x output/2 B Input output C Input – output D Input / output E Input x output.
Jawaban:
E (Input x Output).
Penjelasan:
karena Rumus produktivitas adalah jumlah output dibagi jumlah input. Jadi, produktivitas dapat dihitung dengan mengalikan jumlah input dan jumlah output.
