how do i calculate slope?​

Answers

Answer 1

Answer:

In order to calculate the slope, you'll need 2 ordered pairs (x, y).

The formula for calculating the slope is:

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

where m = slope

(x1, y1) = first ordered pair

(x2, y2) = second ordered pair

Regardless of which values for the (x1, y1) and (x2, y2) you choose, you would still end up with the same slope (as long as it's done correctly).

As an example, let's say you have the following set of points:

(2, 4) (8, 1)

Let (x1, y1) =  (2, 4)

     (x2, y2) = (8, 1)

Plug these values into the slope formula:

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

[tex]m = \frac{1 - 4}{8 - 2} = \frac{-3}{6} = -\frac{1}{2}[/tex]

Therefore, the slope of the line is - 1/2.

To prove that you'll end up with the same value for the slope:

This time, let (x1, y1) =  (8, 1)

                     (x2, y2) = (2, 4)

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

[tex]m = \frac{4 - 1}{2 - 8} = \frac{3}{-6} = - \frac{1}{2}[/tex]

Therefore, the value of the slope is still -1/2.

The solution to the equation is x =   ±[tex]\sqrt{2}[/tex]i +3  

What is a quadratic equation ?

A quadratic equation is an algebraic equation which has highest degree of 2 and it has 2 roots.

In the given question

x² - 6x +13 = 0

x² - 2.x.b + 13 = 0                                          (-2.x.b = -6x ↔ b = 3)

(x - 3)² + 13 = 9                                              ( we have added 9 on r.h.s                                                                

                                                                       because b² = 9 is added on l.h.s)    

(x-3)² = -4

x - 3 = ±[tex]\sqrt{2}[/tex]i  

x =   ±[tex]\sqrt{2}[/tex]i +3

She made a mistake in the second step  she should have added +9 on the right hand side because we have an additional 9 on the left hand side because of the perfect square we have made to make both sides balanced.

x=29

Answer:

From the above attachment we can conclude that,

[tex](2x - 10)° + (4x + 16)° = 180° \\ 2x - 10 + 4x + 16 = 180 \\ 2x + 4x - 10 + 16 = 180 \\ 6x + 6 = 180 \\ 6x = 180 - 6 \\ 6x = 174 \\x = \frac{174}{6} \\ \boxed{x = 29}[/tex]

Therefore, the value of x is 29

x = 29 is the right answer.

Point upper D left parenthesis negative 3 comma 5 right parenthesis. is a vertex of triangle DEF. After a rotation of the triangle about the origin, upper D prime is located at left parenthesis 3 comma negative 5 right parenthesis. Which of the following was the rotation of the triangle?

Answers

The rotation that the triangle DEF underwent is defined as follows:

180º around the origin.

Rotation

A rotation is one example of transformation that a function can undergo, along with transformation, compression, stretching, dilation or reflection.

A rotation changes the inclination of the figure, and the rules for each rotation are given as follows:

90° clockwise rotation: (x,y) -> (y,-x)90° counterclockwise rotation: (x,y) -> (-y,x)180° clockwise and counterclockwise rotation: (x, y) -> (-x,-y)270° clockwise rotation: (x,y) -> (-y,x)270° counterclockwise rotation: (x,y) -> (y,-x)

In this problem, the coordinates are given as follows:

Original: (-3,5).Image: (3,-5).

Hence the rule is:

(x,y) -> (-x, -y).

Meaning that a rotation of 180º around the origin was done.

Answers

Answer:

B. 0.210

Step-by-step explanation:

Range is the minimum value subtracted from the maximum value. In this case 0.004 is the smallest value and 0.214 is the largest.

Range = 0.214 - 0.004 = 0.210 = B

The range set of the given data is 0.21.

The given data sets are,

0.004

0.007

0.011

0.011

0.012

0.020

0.200

0.214

We know that,

In statistics, the range is the difference between the highest and lowest values for a given data collection.

For instance,

if the given data set is 2,5,8,10,3, the range is 10 - 2 = 8.

As a result, the range can also be defined as the difference between the highest and lowest observations.

The range of observation is the name given to the outcome. In statistics, the range indicates the dispersion of observations.

Now to find the range set pf the given data,

Subtract minimum value to maximum value

Since maximum value = 0.214

And minimum value     = 0.004

Then range set = 0.214 - 0.004

                          =  0.21

Thus, range of set  ⇒ 0.21

He did not look at Prissy, nor did she wish him a happy New Years she would not have dared. Uncle Richard had not been on speaking terms with her or her father, his only brother, for eight years.(2) [While in the store, Prissy overhears her uncle Richard explain that he is on his way to a neighboring town, Navarre, and that he has no one to make his New Year's dinner. Prissy decides to go to his house, make a surprise dinner for him, and leave before he returns. She acts on her plan, cooking a dinner at his house. As she prepares to dish it out, she suddenly hears a voice behind her.](3) Well, well, what does this mean?(4) Prissy whirled around as if she had been shot, and there stood Uncle Richard in the woodshed door!(5) Poor Prissy! She could not have looked or felt more guilty if Uncle Richard had caught her robbing his desk. She did not drop the turnips for a wonder; but she was too confused to set them down, so she stood there holding them, her face crimson, her heart thumping, and a horrible choking in her throat.(6) "I I came up to cook your dinner for you, Uncle Richard," she stammered. "I heard you say in the store that Mrs. Janeway had gone home and that you had nobody to cook your New Year's dinner for you. So I thought I'd come and do it, but I meant to slip away before you came home."(7) Poor Prissy felt that she would never get to the end of her explanation. Would Uncle Richard be angry? Would he order her from the house?(8) "It was very kind of you," said Uncle Richard dryly. "It's a wonder your father let you come."(9) "Father was not home, but I am sure he would not have prevented me if he had been. Father has no hard feelings against you, Uncle Richard."(10) "Humph!" said Uncle Richard. "Well, since you've cooked the dinner you must stop and help me eat it. It smells good, I must say. Mrs. Janeway always burns pork when she roasts it. Sit down, Prissy. I'm hungry."(11) They sat down. Prissy felt quite giddy and breathless, and could hardly eat for excitement; but Uncle Richard had evidently brought home a good appetite from Navarre, and he did full justice to his New Year's dinner. He talked to Prissy too, quite kindly and politely, and when the meal was over he said slowly:(12) "I'm much obliged to you, Prissy, and I don't mind owning to you that I'm sorry for my share in the quarrel, and have wanted for a long time to be friends with your father again, but I was too ashamed and proud to make the first advance. You can tell him so for me, if you like. And if he's willing to let bygones be bygones, tell him I'd like him to come up here with you tonight when he gets home and spend the evening with me."(13) "Oh, he will come, I know!" cried Prissy joyfully. "He has felt so badly about not being friendly with you, Uncle Richard. I'm as glad as can be."(14) Prissy ran impulsively around the table and kissed Uncle Richard. He looked up at his tall, girlish niece with a smile of pleasure.(15) "You're a good girl, Prissy, and a kind-hearted one too, or you'd never have come up here to cook a dinner for a crabbed old uncle who deserved to eat cold dinners for his stubbornness.

But it has brought me happiness already, and I believe it will be a happy year all the way through."(16) "Indeed it will!" laughed Prissy. "I'm so happy now I could sing. I believe it was an inspiration my idea of coming up here to cook your dinner for you."(17) "You must promise to come and cook my New Year's dinner for me every New Year we live near enough together," said Uncle Richard.(18) And Prissy promised.Describe the storys resolution.
