Solve the inequality:

[tex]\[ 12 + \frac{40}{f} \ \textgreater \ 44 \][/tex]

Options:
A. [tex]\( f = 5 \)[/tex]
B. [tex]\( f = 10 \)[/tex]
C. [tex]\( f = 1 \)[/tex]
D. [tex]\( f = 8 \)[/tex]

Answer :

Let's solve the inequality step-by-step:

We have the inequality:

[tex]\[ 12 + \frac{40}{f} > 44 \][/tex]

We need to determine which value of [tex]\( f \)[/tex] makes this inequality true from the options given: [tex]\( f = 5 \)[/tex], [tex]\( f = 10 \)[/tex], [tex]\( f = 1 \)[/tex], [tex]\( f = 8 \)[/tex].

Let's evaluate the expression for each value of [tex]\( f \)[/tex]:

1. When [tex]\( f = 5 \)[/tex]:

[tex]\[ 12 + \frac{40}{5} = 12 + 8 = 20 \][/tex]

This value is not greater than 44, so [tex]\( f = 5 \)[/tex] does not satisfy the inequality.

2. When [tex]\( f = 10 \)[/tex]:

[tex]\[ 12 + \frac{40}{10} = 12 + 4 = 16 \][/tex]

This value is not greater than 44, so [tex]\( f = 10 \)[/tex] does not satisfy the inequality.

3. When [tex]\( f = 1 \)[/tex]:

[tex]\[ 12 + \frac{40}{1} = 12 + 40 = 52 \][/tex]

This value is greater than 44, so [tex]\( f = 1 \)[/tex] does satisfy the inequality.

4. When [tex]\( f = 8 \)[/tex]:

[tex]\[ 12 + \frac{40}{8} = 12 + 5 = 17 \][/tex]

This value is not greater than 44, so [tex]\( f = 8 \)[/tex] does not satisfy the inequality.

The only value of [tex]\( f \)[/tex] that makes the inequality true is [tex]\( f = 1 \)[/tex].
