Question

May anyone please help me with math​

Answer 1

In decimal

`- 2.8`

As fraction

`( - 14)/(5)`

And as mixed fraction

`- 2 (4)/(5)`

Explanation:

Greetings !

Given expression

`f(x) = (x - 8)/(x + 11)`

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

`f( - 6) = ( - 6 - 8)/( - 6 + 11)`

solve -6-8 = -14

solve -6+11 = 5

`= ( - 14)/(5)`

Apply fraction rule

`( - a)/(b) = - (a)/(b)`

Thus

`= - (14)/(5)`

Convert iimproper fraction to mixed fraction .

`(14)/(5) = 2 \: \: remainder \: \: 4`

`convert \: to \: mixed \: number \\ quotient (remainder)/(divisor)`

whereas

`(14)/(5) = 2 (4)/(5)`

`= - 2 (4)/(5)`

Hope it helps !!!
