Identify the restrictions on the domain of f(x) = x+2/x-3<br> x≠-2<br> x≠2<br> x≠-3<br> x≠3
erma4kov [3.2K]

Answer:

  x ≠ 3

Step-by-step explanation:

The denominator of ...

  f(x) = (x+2)/(x -3)

is zero when x=3, so the function is not defined there. Values of x for which the function is not defined are not part of the domain.

The restriction is: x ≠ 3.

_____

Please note that parentheses are required around numerators and denominators when a rational function is written in plain text. When it is typeset:

  f(x)=\dfrac{x+2}{x-3}

the division bar serves as a grouping symbol. In plain text, we cannot tell where numerator and denominator begin and end unless some other grouping symbol (parentheses) is used.

<h2>Answer:You can buy a ticket.</h2>

Step-by-step explanation:

It is given that 9 people bought tickets in 70 seconds.

So,\frac{9}{70} people can buy tickets in a second.

It is given that the current time is 6:09pm and movie starts at 6:30pm.

So there is 30-9=21minutes until movie starts.

In 21 minutes,the number of persons that can buy tickets are \frac{9}{70}\times 21\times 60=162.

So,162 people can buy tickets in 21 minutes.

Since there are only 146 people in front of you,you can buy a ticket.

Someone please solve this for me!
mezya [45]

Answer:

  x = 149

Step-by-step explanation:

The transversal <em>t</em> crosses parallel lines <em>m</em> and <em>n</em> creating a number of angles. Both marked angles are above and to the right of the point of intersection, so they are <em>corresponding angles</em>.

Corresponding angles in this geometry have identical measures:

  x° = 149°

  x = 149

Solve the following radical equations. 5√x−6=−20 Answer choices: x=−10 x=10 x=22 No solution
myrzilka [38]

Answer:

Step-by-step explanation:

5 \sqrt{x} -6=-20

1. You divide 5 by both sides, which will give you \sqrt{x-6}=-4

2. You then square both sides of the equation, which will give you x-6=16

3. Since the equation is now one-step, you then do GEMDAS and you will get x=22
