Simplify<br> −6+{14+2[60−9(1+3)]}

ziro4ka [17]

The answer is 56.

I know this because...
<span>-6 + {14 + 2 [60 − 9(1 + 3)]}
-6 + </span>{14 + 2[60 − 9(4)]}
-6 + {14 + 2[60 − 36]}
-6 + {14 + 2[24]}
-6 + {14 + 48}
-6 + {62}
-6 + 62 = 56

Find the domain for the rational function f of x equals quantity x end quantity divided by quantity x minus 5 end quantity.

Gennadij [26K]

Answer:

All real numbers except for 5.

Step-by-step explanation:

$f(x)=\frac{x}{x-5}$

The domain of rational functions is determined by the denominator. The denominator cannot equal zero since if they do, the function will be undefined.

Thus, we need to find the zero(s) of the denominator to determine the domain.

$x-5=0$
