A charter airline finds that on its Saturday flights from Philadelphia to London all 180 seats will be sold if the ticket price
Darina [25.2K]

Answer:

S = -\dfrac{1}{3}P+\dfrac{740}{3}

Step-by-step explanation:

Given that:

Number of seats sold is 180 with ticket price $200.

Number of seats decreases by one when the ticket price is increased by $3.

To find:

The formula for the number of seats sold (S) when the ticket price is P dollars.

Solution:

It is linear dependency of number of seats sold, S on ticket price, P.

S\propto P

It can be written as:

S = kP+C

Where k is the constant of proportionality and

C is a constant.

Now, putting the given values:

180  = 200k +C ..... (1)

179 = 203k+C ...... (2)

Subtracting (1) from (2):

3k = -1\\\Rightarrow k =-\dfrac{1}{3}

Putting the value in (1):

\Rightarrow C = 180+\dfrac{200}{3} = \dfrac{740}{3}

Therefore the equation becomes:

S = -\dfrac{1}{3}P+\dfrac{740}{3}

What are the two solutions of 2x2 = –x2 – 5x – 1?
77julia77 [94]

Answer:

The answer is

<h3>x =  \frac{ - 5 +  \sqrt{13} }{6}  \:  \:  \:  \: or \:  \:  \: x  =  \frac{ - 5 -  \sqrt{13} }{6}</h3>

Step-by-step explanation:

2x² = - x² - 5x - 1

<u>Rearrange the terms and simplify</u>

That's

2x² + x² + 5x + 1 = 0

3x² + 5x + 1 = 0

Using the quadratic formula solve the equation

That's

<h3>x =  \frac{ - b\pm \sqrt{ {b}^{2}  - 4ac} }{2a}</h3>

From the question

a = 3 , b = 5 , c = 1

So we have

<h3>x =  \frac{ - 5\pm \sqrt{ {5}^{2} - 4(3)(1) }}{2(3)}  \\  =  \frac{ - 5\pm \sqrt{25 - 12} }{6}  \\   = \frac{  - 5\pm \sqrt{13} }{6}</h3>

We have the final answer as

<h3>x =  \frac{ - 5 +  \sqrt{13} }{6}  \:  \:  \:  \: or \:  \:  \: x  =  \frac{ - 5 -  \sqrt{13} }{6}</h3>

Hope this helps you
