2. f(x) = 3ǀ2x - 1ǀ + x, what is the output for the input -4? <br> im stumped pls help
rewona [7]

Answer:

output = 23

Step-by-step explanation:

x = -4

f(x) = 3ǀ2x - 1ǀ + x

f(x) = 3ǀ2(-4) - 1ǀ + (-4)

f(x) = 3ǀ2(-4) - 1ǀ - 4

f(x) = 3ǀ-8 - 1ǀ - 4

f(x) = 3ǀ-9ǀ - 4

f(x) = 3(9) - 4

f(x) = 3(9) - 4

f(x) = 27 - 4

f(x) = 23

Hiii guys i need help with my homewrok <img src="https://tex.z-dn.net/?f=-9%5Cleq%207-8x" id="TexFormula1" title="-9\leq 7-8x" a
Illusion [34]

Answer:

The answer is x ≤ 2.

Step-by-step explanation:

Firstly, you have to move the unrelated term to the other side :

- 9 \leqslant 7 - 8x

- 9 - 7 \leqslant  - 8x

- 16 \leqslant  - 8x

Next you can solve it :

- 8x \geqslant  - 16

x \leqslant  - 16 \div  - 8

x \leqslant 2

*Remember to change the symbol, when it is dividing by a negative value
