Answer:

In decimal

[tex] - 2.8[/tex]

As fraction

[tex] \frac{ - 14}{5} [/tex]

And as mixed fraction

[tex] - 2 \frac{4}{5} [/tex]

Step-by-step explanation:

Greetings !

Given expression

[tex]f(x) = \frac{x - 8}{x + 11} [/tex]

Thus, plug in -6 in the variable x and solve

[tex]f( - 6) = \frac{ - 6 - 8}{ - 6 + 11} [/tex]

solve -6-8 = -14

solve -6+11 = 5

[tex] = \frac{ - 14}{5} [/tex]

Apply fraction rule

[tex] \frac{ - a}{b} = - \frac{a}{b} [/tex]

Thus

[tex] = - \frac{14}{5} [/tex]

Convert iimproper fraction to mixed fraction .

[tex] \frac{14}{5} = 2 \: \: remainder \: \: 4[/tex]

[tex]convert \: to \: mixed \: number \\ quotient \frac{remainder}{divisor} [/tex]

whereas

[tex] \frac{14}{5} = 2 \frac{4}{5} [/tex]

[tex] = - 2 \frac{4}{5} [/tex]

Hope it helps !!!
