Hello!

First off, (-inf, -2) was half of the domain, so you were right on track, but almost there!

Since this function has a vertical asymptote at x = -2, any x-values that are equal to -2 cause the function to be undefined. So, we show that as (-∞, -2) because this function is a continuous function from that interval.

Since this function is also continuous from the interval -2 to ∞, we show that as the second part of our domain; written as (-2, ∞).

Remember that parentheses and brackets have different meanings when using them to state the domain/range of a function. Parentheses are used to <u>not</u> include that value, while brackets are used <u>to</u> include it.

In that case, we need to combine this two intervals using the "union" symbol, which is "U".

Therefore, the domain of the function is (-∞, -2) U (-2, ∞).

Which of the following inequalities is equivalent to 3-(w+2)&gt;4+2w
Kay [80]

3 - w - 2 > 4 + 2w  \\  - w - 2w > 4 + 2 - 3 \\  - 3w > 6 - 3 \\   \frac{ - 3w}{ - 3}  >  \frac{3}{ - 3} \\ w <  - 1
The sign at the end changes because both sides of the equation are being divided by a negative number.

A rug is shaped like a rectangle whose perimeter is 276276 ftft. the length is 5 times as long as5 times as long as the width. f
ArbitrLikvidat [17]
Width = w

Length = 5w

Given,

Perimeter = 276 ft

5w * w = 276

w² = 55.2

--- w = 7.429670248402684 ≈ 7.43 ft

--- l = 5w = 5*7.43 = <span>37.14835124201342 </span>≈ 37.15 ft

= neage Check Find the distance between the polnts (6,-5) and (-3,-5). ​
miskamm [114]

Answer:

The answer is

<h2>9 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3>d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(6,-5) and (-3,-5)

The distance between them is

<h3>d =  \sqrt{ ({6 + 3})^{2} + ( { - 5 + 5})^{2}  }  \\   = \sqrt{ {9}^{2} +  0 }  \\  =  \sqrt{81}</h3>

We have the final answer as

<h3>9 units</h3>

Hope this helps you
