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

x=5

Therefore, the domain of the rational function is all real numbers except for 5.

In set builder notation, this is:

\{x|x\in \mathbb{R}, x\neq 5\}

8(7n-2) -6(7n+1)<br><br> Explain please
Verizon [17]

Answer:

<h2>8(7n - 2) - 6(7n + 1) = 14n - 22</h2>

Step-by-step explanation:

8(7n - 2) - 6(7n + 1)

use the distributive property: a(b + c) = ab + ac

= 8 · 7n + 8 · (-2) + (-6) · 7n + (-6) · 1

= 56n - 16 - 42n - 6

combine like terms

= (56n - 42n) + (-16 - 6)

= 14n - 22

spayn [35]

Answer:

15

Step-by-step explanation:

Note: Take note , absolute value will give the magnitude of the value. (Which means ignoring the + / - signs.)

Eg. | - 19 | = 19

Therefore,

\frac{12(30 - (9 +  {4}^{2})) }{10 -  | - 6| }  \\  =  \frac{12(30 - (9 + 16))}{10 - 6}  \\  =   \frac{12(30 - 25)}{4}  \\  =  \frac{12(5)}{4}  \\  =  \frac{60}{4}  \\  = 15
