Simple..

you have y which is the cost of the tickets..and you have x which is the number of tickets..

So, you have those points on the graph....find an equation!

Take any of those coordinates..and find the equation of the line...in the form of y=mx+b

(2,10) and (5,25)

Using: \frac{ y_{1}- y_{2}  }{ x_{1}- x_{2}  }

\frac{10-25}{2-5} = \frac{-15}{-3} =5

Thus, you know your slope. m=5

But, remember it's in the form of y=mx+b

So, use any of the coordinates...let's use (2,10)

10=5(2)+b

10=10+b

0=b

Thus, your equation is... y=5x

Thus, your answer.

Math-Limits and Derivative. Could anybody help me,please ?
Serhud [2]

Answer:

Step-by-step explanation:

Hello, please consider the following.

\displaystyle f'(0)=\lim_{x\rightarrow0} {\dfrac{f(x)-f(0)}{x-0}}\\\\=\lim_{x\rightarrow0} {\dfrac{\dfrac{\sqrt{1+x}-1}{x}-k}{x}}\\\\=\lim_{x\rightarrow0} {\dfrac{\dfrac{\sqrt{1+x}-1-kx}{x}}{x}}\\\\=\lim_{x\rightarrow0} {\dfrac{\sqrt{1+x}-1-kx}{x^2}}\\

Thank you

Answer: Let’s use the Pythagorean theorom!

A^2+B^2=C^2

10^2+B^2=15^2

Find the probability of drawing a heart from the standard deck of cards and then drawing a 5 from any suit after the first card
Vinil7 [7]

The probability of drawing a heart from the standard deck of cards and then drawing a 5 is 1/52

<h3>How to determine the probability?</h3>

In a standard deck of cards, we have:

Total = 52

Heart = 13

5's = 4

Since the cards are replaced, the probability is calculated as:

P(Heart and 5) = Heart/Total * 5s/Total

This gives

P(Heart and 5) = 13/52* 4/52

Evaluate

P(Heart and 5) = 1/52

Hence, the probability of drawing a heart from the standard deck of cards and then drawing a 5 is 1/52
