Find the coordinates of the midpoint of a segment with the given endpoints (7,0) and (2,4)

Answers

Answer:

[tex]MP= (4.5,2)[/tex] another way of writing [tex]MP= (\frac{9}{2}, 2)[/tex]

Step-by-step explanation:

[tex]MP= (\frac{x_1+x_2}{2})(\frac{y_1+y_2}{2})[/tex]

[tex]MP= (\frac{7+2}{2})(\frac{0+4}{2})[/tex] 7+2=9 0+1=1

[tex]MP= (\frac{9}{2})(\frac{2}{2})[/tex]  MP= (4.5,2)

The coordinates of the mid - point of XY will be -  M(4.5, 2)

We have two coordinate points - X(7, 0) and  Y(2, 4).

We have to find the coordinates of the mid - point of the line segment XY.

What is Mid - Point Theorem?

It states that a line with endpoint coordinates as - [x(1), y(1)] and

[x(2), y(2)] has its mid - point at the coordinates -

[tex]$x(m) =\frac{x(1)+x(2)}{2}[/tex]

[tex]$y(m) = \frac{y(1)+y(2)}{2}[/tex]

According to question, we have -

Assume that the coordinates of Mid - Point = M(h, k)

Coordinates of X= (7, 0)

Coordinates of Y= (2, 4)

Using the Mid - Point formula -

h = [tex]\frac{7+2}{2}[/tex] = 4.5

and

k = [tex]\frac{0+4}{2}[/tex] = 2

Hence, the coordinates of the mid - point of XY will be -  M(4.5, 2)

We add 12 to both sides
9x=13+14x+12
Simplify it we get
9x=4x+25
Subtract 4x from both sides
9x-4x=25
We simplify it and we get
5x=25
Divide both sides by 5
X=25/5
And we get x=5 as the answer

1. Reflection across y-axis and translated down 1 unit

2. 270 degree counterclockwise rotation and translated right three units.

Step-by-step explanation:

For number 1, when you reflect across the y-axis, the polygon is one unit above the intended location, so you would move it down one.

For number two, when you rotate it 270 degrees counterclockwise, it is to the left three units, so you would move it to the right three units.

Givenf(x)=6(8−x)+5.
(a) What does the notation f (−2) mean? (b) What is the value of f (−2) ?

Answers

Answer:

b. 65

a. The notation f(-2) means that we want to evaluate the value of the equation when x = -2

Step-by-step explanation:

A. The notation f(-2) means that we want to evaluate the value of the equation when x = -2

B. We will simply substitute the value of 2 for x

f(x) = 6(8-x) + 5

f(-2) = 6(8 - (-2)) + 5

f(-2) = 6(8 + 2) + 5

f(-2) = 6(10) + 5 = 60 + 5 = 65

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The system of equations are:

5x + y = 2

2y = 4 − 10x

The system of equations can be written as:

5x + y = 2 ..(I)

10x + 2y = 4 ...(II)

In equation (II) divide by 2

5x + y = 2 ..(III)

Equations (I) and (III) represent the same equation:

The system of equations represents the Dependent because the solution to the system of equations has infinitely many solutions.

Thus, the system of equations represents the dependent because the solution to the system of equations has infinitely many solutions.

Answer:

2x - 2y or x -2y or 0pick one out of the three

Answer:

B

Step-by-step explanation:

So we have the equation:

[tex]4xz-4yz=5[/tex]

And we want to find the value of 5/4x in terms of x and y.

From our original equation, let's factor out a 4z from the left. So:

[tex]4z(x-y)=5[/tex]

Now, divide both sides by 4z:

[tex]x-y=\frac{5}{4z}[/tex]

Therefore, the expression that represents 5/4z is x-y.

The correct answer is B.

The Kingdoms James Baldwin There was once a king of Prussia whose name was Frederick William. On a fine morning in June he went out alone to walk in the green woods. He was tired of the noise of the city, and he was glad to get away from it. So, as he walked among the trees, he often stopped to listen to the singing birds, or to look at the wild flowers that grew on every side. Now and then he stooped to pluck a violet, or a primrose, or a yellow buttercup. Soon his hands were full of pretty blossoms. After a while he came to a little meadow in the midst of the wood. Some children were playing there. They were running here and there, and gathering the cowslips that were blooming among the grass. It made the king glad to see the happy children, and hear their merry voices. He stood still for some time, and watched them as they played. Then he called them around him, and all sat down together in the pleasant shade. The children did not know who the strange gentleman was; but they liked his kind face and gentle manners. "Now, my little folks," said the king, "I want to ask you some questions, and the child who gives the best answer shall have a prize." Then he held up an orange so that all the children could see. "You know that we all live in the kingdom of Prussia," he said; "but tell me, to what kingdom does this orange belong?" The children were puzzled. They looked at one another, and sat very still for a little while. Then a brave, bright boy spoke up and said,-- "It belongs to the vegetable kingdom, sir." "Why so, my lad?" asked the king. "It is the fruit of a plant, and all plants belong to that kingdom," said the boy. The king was pleased. "You are quite right," he said; "and you shall have the orange for your prize." He tossed it gayly to the boy. "Catch it if you can!" he said. Then he took a yellow gold piece from his pocket, and held it up so that it glittered in the sunlight. "Now to what kingdom does this belong?" he asked. Another bright boy answered quickly, "To the mineral kingdom, sir! All metals belong to that kingdom." "That is a good answer," said the king. "The gold piece is your prize." The children were delighted. With eager faces they waited to hear what the stranger would say next. "I will ask you only one more question," said the king, "and it is an easy one." Then he stood up, and said, "Tell me, my little folks, to what kingdom do I belong?" The bright boys were puzzled now. Some thought of saying, "To the kingdom of Prussia." Some wanted to say, "To the animal kingdom." But they were a little afraid, and all kept still. At last a tiny blue-eyed child looked up into the king's smiling face, and said in her simple way,-- "I think to the kingdom of heaven." King Frederick William stooped down and lifted the little maiden in his arms. Tears were in his eyes as he kissed her, and said, "So be it, my child! So be it." The king's interaction with the children may best be described asA)lecturing.B)explaining.C)provocative.D)interrogating.
