Answer:

y=-2x

Step-by-step explanation:

if x<-5

x+5<0

x-5 also<0

so

|x-5|=-(x-5)=-x+5

|x+5|=-(x+5)=-x-5

Hence

y=-x+5-x-5

or

y=-2x,if x<-5

Answer:

x= -5

Step-by-step explanation:

f(x)  =  [ x^2  -  25 ] / [ x + 5 ]  =  [ (x + 5) ( x- 5)]  / [ x + 5 ]  =  x - 5

This will be the graph of  f(x) =   x - 5  with a  "hole"  at   x  =  - 5

The graph of the rational function f(x) = (x² - 25)/(x + 5) is represented by the graph second option (B) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The equation of the rational function:

f(x) = (x² - 25)/(x + 5)

As we know, in the rational function the denominator cannot be zero.

x + 5 ≠ 0

x ≠ -5 (there will be a hole at x = -5)

f(x) = (x - 5)(x + 5)/(x + 5)

Because: a² - b² = (a - b)(a + b)

f(x) = (x - 5)

The above function represents the linear function.

The slope of the linear function is positive.

m = 1

The y-intercept of the linear function is c = -5

Thus, the graph of the rational function f(x) = (x² - 25)/(x + 5) is represented by the graph second option (B) is correct.

I have a parrot

I have an African grey parrot, his name is Yaco (pronounce the "a" in his name the same way you'd pronounce the "a" in taco lol). He's 23 years old and the species can normally live in the range of 50-85 years old! Yes! He does do things on his own, eat, drink, play, and talk. One question you asked is "Does he ever steal food?" No, but he's worse than the dog when it comes to begging for human foods and snacks, he can have quite a vary of human foods such as some fruits, nuts, and crackers and such. Also, he has about a 300 word vocabulary and with a wide range of different sounds and noises. And with him being a parrot, he's picked up all these words, phrases, and sounds from people and movies and pets that are always often around him and in our home. He has been around 7 years longer than me. He's a very neet and VERY smart bird. In your free time go onto you.tube and search up 'Einstein the talking african grey parrot' it'll give you an idea of their intelligence.

Step-by-step explanation:

i took the test

The formula that describes this function is c = 50t + 200

A linear equation is in the form:

y = mx + b

Where y,x are variables, m is the rate of change  and b is the y intercept.

Let c represent the distance june has traveled after time t.

Since the cities are 200 miles apart, hence b = 200. Also the spoeed is 50 mph, hence m = 50:

c = 50t + 200

The formula that describes this function is c = 50t + 200

   x = 8

Step-by-step explanation:

The halves of a bisected segment are congruent, so we have ...

First step, plug 1 in for X

a. The determination of the break-even number of subscribers for Star Stream is as follows:

Break-even number of subscribers = Fixed Costs/Contribution Margin per subscriber

= 35,294,118 ($3,000,000,000/$85)

b. If Star Stream increases the annual content costs to $2,600,000,000, the break-even number of subscribers will increase to 42,352,941 subscribers.

= 42,352,941 ($3,600,000,000/$85)

c. The annual subscription needs to increase from $120 to $142 to maintain the same break-even as in (a).

The break-even analysis is a financial tool for determining the price level at which the total revenue equals the total costs (variable and fixed).

Using the break-even analysis model, one can determine the number of units to sell so that fixed costs are recovered.

Server lease costs per year = $100,000,000

Content costs per year = $2,000,000,000

Fixed operating costs per year = $900,000,000

Total fixed costs per year = $3,000,000,000

Bandwidth costs per subscriber per year = $15

Variable operating costs per subscriber per year = $25

Subscription per year = $125

Contribution margin per subscriber per year = $85 ($125 - $15 - $25)

Contribution margin ratio = 68% ($85/$125 x 100)

a. Determine the break-even number of subscribers.

b. Assume Star Stream planned to increase available programming and thus increase the annual content costs to $2,600,000,000. What impact would this change have on the break-even number of subscribers?

c. Assume the same content cost scenario in (b). How much would the annual subscription need to change to maintain the same break-even as in (a)?

Thus, with an annual subscription of $142, the variable cost of $40 per subscriber per year, contribution margin of $102 ($142 - $40), and a total fixed cost of $3,600,000,000, the break-even number of subscribers will remain 35,294,118 ($3,600,000,000/$102).

Answer:

-37

Step-by-step explanation:

for the first equation to equal 4 the x must equal -6.

because something plus 7 had to equal 4. and we know that -3 + 7 equals 4. Now, -6 ÷ 2 equals -3 and that gives us the right answer.

So now plug -6 into the new problem so now it is

5 × (-6) - 7 so according the PEMDAS, we do 5 × -6 first which is -30. and -30 - 7 equals -37!!

The magnitude of an earthquake that is 35 times more intense than a standard earthquake is 1.5.

The magnitude of an earthquake is the measured of the amplitude r the size of the seismic waves which is produced by the earthquake.

The magnitude, m, of an earthquake is defined to be

[tex]m = \log\left( \dfrac{I}{S}\right)[/tex]

Here (I) is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and (S) is the intensity of a "standard" earthquake, which is barely detectable.

The magnitude of an earthquake that is 35 times more intense than a standard earthquake has to be find out. The Intensity of this earth quack can be given as,

[tex]I=35S[/tex]

Put this values in the above formula as,

[tex]m = \log\left( \dfrac{35 S}{S}\right)\\m = \log\left( 35 \right)\\m\approx 1.5[/tex]

Thus, the magnitude of an earthquake that is 35 times more intense than a standard earthquake is 1.5.
