Write the equation of the line that passes through the points (2,0) and (1,-2)

Darya [45]

Answer:

y

=

x

−

Explanation:

First, we need to determine the slope of the line. The formula for determining the slope of a line is:

m

=

y

−

y

−

x

where

m

is the slope and the x and y terms are for the points:

(

x

1

,

y

1

)

and

(

x

,

y

)

For this problem the slope is:

Now, selecting one of the points we can use the point slope formula to find the equation.

The point slope formula is:

y

Substituting one of our points gives:

How can Ari simplify the following expression? StartFraction 5 Over a minus 3 EndFraction minus 4 divided by 2 + StartFraction 1

Zielflug [23.3K]

Answer:

$-\frac{8}{3}$

Step-by-step explanation:

Given

$\frac{5}{-3} - \frac{4}{2} + \frac{1}{-3}$

Required

Simpify

The very first step is to take LCM of the given expression

$\frac{-10 -4 - 2}{6}$

Perform arithmetic operations o the numerator

$-\frac{16}{6}$

Divide the numerator and denominator by 2

$-\frac{16/2}{6/2}$

$-\frac{8}{3}$

The expression can't be further simplified;

Hence, $\frac{5}{-3} - \frac{4}{2} + \frac{1}{-3}$ = $-\frac{8}{3}$

Hi, Laura! ;)

<h2>The answer to the first question is 5,62.</h2>

<h2><em>Here is the step by step solution</em>: </h2>

They want to know the center of a distribution. Another word for center is middle. When you have a set of numbers, you can find the middle by calculating the mean, the "average" of the data set.

1) Add all the numbers: 12,8 + 5,7 + 7,9 + 1,3 + 3,2 + 2,8 = 33,7

2) Divide the sum by the quantity of numbers, which is 6: 33,7 / 6 = 5,616

The closest number to 5,616 is 5,62.

==========================================================

Now let's answer your second question.

<h2>The correct answer is, indeed, 0,14.</h2>

<h2><em>How do we get to this number? Here is the step by step solution:</em></h2>

1) First step is to find out how many possible outcomes you have. It is the

number of raffle tickets in the box: 200.

2) Then, let's define the number of tickets that are prizes: 4 + 8 + 16 = 28.

The probability of selecting a prize ticket is the number of prize tickets divided by all the raffle tickets in the box: 28 / 200 = 0,14.

Now, let's practice Probability with another Brainly problem:

Good luck, Laura! :)
