Mathematics
1 answer:
avanturin [10]3 years ago
3 0

Answer:

\{x \in R | x \neq 3\}

\{x \in R | x < 3 \cup x > 3\}

\{x | x > 3, x \in R\} \cup\{x | x < 3, x \in R\}

Step-by-step explanation:

To find the domain of a rational expression like \frac{14x}{x-3} you need to find out where the denominator is 0 because you cannot divide by 0

So, take the denominator x - 3 and set it to zero and solve for x

x - 3 = 0

x = 3

So the domain is all real numbers but where x = 3. You can write this in a few different ways in set notation.

---------------------------------------

NOTE

R = real numbers

\in = element of

| = such that

---------------------------------------

\{x \in R | x \neq 3\}

<u>Or you could write it this way</u>

\{x \in R | x < 3 \cup x > 3\}

<u>Or you could write it this way</u>

\{x | x > 3, x \in R\} \cup\{x | x < 3, x \in R\}

Which inequality best represents that ice cream at −3°C is cooler than ice cream at 1°C? (4 points)
Leno4ka [110]

Answer:

-3° C < 1°C is the correct option.

Step-by-step explanation:

As we know that:

  • The inequality symbol '<' means 'less than'.
  • The inequality symbol '>' means 'more than'.

If someone says that something is cooler than the other thing, it indicates that it is lesser than the other based on its temperature.

As the ice cream at −3°C is cooler than ice cream at 1°C, it indicates that temperature -3° C < temperature  1°C.

Therefore, -3° C < 1°C is the correct option.
