The points (-1, r) and (2, 1) lie on a line with slope 2. Find the missing coordinate r
Please help!!!

Answers

Answer 1

Answer:

r = -5

Step-by-step explanation:

Slope = (y2 - y1)/(x2 - x1)

(-1, r)

(2, 1)

r - 1/-1 - 2 = r - 1/-3

Slope = 2

-3 x 2 = -6

-6 -(-1) = -5

-5 - 1 = -6

-6/-3 = 2

So:

r = -5

Hope this helps!

Answer 2

9514 1404 393

Answer:

  r = -5

Step-by-step explanation:

The x-coordinate of the partially-defined point is 3 units less than the x-coordinate of the given point. The slope of 2 tells you the y-coordinate of the partial point (r) will be 2·3 = 6 units less than the y-coordinate of the given point. That is ...

  r = 1 - 2·3

  r = -5

__

You are given the slope of the line and a point on it, so you can write the point-slope equation of the line:

  y -y1 = m(x -x1) . . . . . . . line with slope m through point (x1, y1).

For the given point and slope, this is ...

  y -1 = 2(x -2)

For an x-value of -1, the corresponding y-value will be ...

  r = 2(-1-2) +1 = -6 +1

  r = -5

Five different awards are to be given to three students. Each student will receive at least one award. In how many different ways can the awards be distributed?

Answers

Answer:

Two ways

Step-by-step explanation:

Blue is students and Yellow is the trophies.

Total number of different ways that the awards can be distributed is; 150 ways.

It is clear from the question that the awards and the students are different. Now, each student will receive at least one award.

This means that the five different awards could be separated into;

3 + 1 + 1 awards or 2 + 2 + 1 awards.

Now, for one person to get 3 awards and the other 2 people to get one award each, the number of ways is calculated as;

       ⁵C₃ × 3! = 60 ways

Now, for the case where one person is to get 1 award and the other 2 people to get two awards each, the number of ways is calculated as;

      ((⁵C₂ × ³C₂)/2) × 3! = 90 ways

Thus; total number of ways the awards can be distributed = 60 + 90 = 150 ways.

What are the negative and positive coterminal angles of 240 degrees?

Answers

-120 negative and 600 positive.

The negative and positive coterminal angles of 240 degrees will be -120 negative and 600 positive.

What are coterminal angles?

Two different angles that have identical starting and ending edges are termed coterminal angles however since one angle is measured clockwise and the other is determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.

We have to find the coterminal angles of 240 degrees

Coterminal angles are those whose initial and terminal sides coincide. Depending on whether the given angle is in degrees or radians, adding or subtracting 360° or 2 from each angle yields the coterminal angles. There are countless coterminal angles that can be discovered.

Thus, the negative and positive coterminal angles of 240 degrees will be -120 negative and 600 positive.

Can someone plz help me with this????

Answers

what information are you given??

Answer:

since we cant see what info is given maybe these tips can help...

the 'b' is also called the y-intercept, the y-int is what you start of with. Example, if your parents give you $20 and you spend $5 every week, your y-int is 20

The m is the slope, so if your parents give you $20 and you spend $5 every week, your slope is -5 because your money is decreasing at a linear rate

the x is the input, so if you want to know how much money you have 2 weeks after you got $20, you would substitute x with 2, and solve to get $10
