Greece) (***) (is the first word) (word brand name).

The name of the word).

Summary. Hello, I have a question that I won't do.

Teacher: I would like to ask how to find the coordinates of point A2023 and what is the law of finding point A on the abscissa?

Dear, take Xun to talk in detail about the situation of your problem, such as the fruit of the mountain branch is that there is a commetic point in a straight line, and then according to the distance between the two points, you can find the coordinates of another point.

If you know the coordinates of the two points, that is to say, in the Cartesian plane coordinate system, the distance between the two points can be calculated according to the Hook Sui search stock Qiaoxun theorem.

Dear, okay, I received a **, I hope to wait patiently for a while and I will come to see**.

If it is a regular triangle, then its side length is equal to 2

Dear, then you just calculate the vertex coordinates, and you can get the analytic expression of the inverse proportional function.

In this way, you can calculate the vertex of this triangle, coordinates p1(1, 3).

Well, the inverse proportional analytic formula y k xy 3 x

Pro, then the next step is to calculate the coordinates of a2, you can make the small triangles into high p2d, and then set the unknown a1d absolute liquid a, so od=2+ap2d 3a At this time, the coordinates of the p2 point are (2+a, 3a).

Pro, and then according to the analytic substitution of (2+a) 3a with thick 3 to get the width of the shirt a +2a-1 0a 2-1 negative discarded or old bright, because it is in the first quadrant.

In this way, the abscissa coordinate can get 2+ 2-1+ 2-1 2 2 2 Of course, the ordinate is zero! Now you can see it.

Take a look at it first.

Teacher, how do you ask for A2023?

The title does not have this point.

Where is 2023.

Hello? Dear, please speak, please speak.

Teacher, how to find the coordinates of the second question point A2023 in this question? Is there any pattern?

Dear, the above calculation for you is the second question, the second question, there is no 2023, this data is the coordinates of A2.

Summary. This is the knowledge of the collection, and there is a question that cannot be written.

This is the knowledge of the collection, and you are the first to ask a few questions.

None of them. Question 1: Yes.

There are 0 1 there are 0, 1 there is none. Not.

It's gone. That's all, you're right.

Just two elements.

0 and 1 guess you haven't already.

There are only two elements to this.

Isn't a set of summation formulas for proportional sequences come out?

a1=i, q=i, so sn=a1(1-q n) (1-q)s2020=i(1-i 2020) (1-i) because 2020 is a multiple of 4, so i 2020=1, so the numerator is 0, so s2020=0

You can give the question directly, but you don't have this question, and you haven't made it clear, so there is no way to help you.

If you look for the law first, you will find that it is five five presentations, and the sum of the first five is exactly i 2020 5 = 404, which is 404i

Which question are you talking about? If you don't say anything, how can you possibly know the answer? This netizen should be a brain problem, right?

Which grade is this?

Hell knows! You don't talk about the topic.

On a circular track with a circumference of 240 meters, starting from the same place and going in opposite directions, meeting in 4 minutes, the sum of the speed of the two brothers is 240 4 = 60 meters min.

Let the younger brother's speed be x m minutes, then the elder brother's speed is 60-x m min If they start from the same place at the same time and travel in the same direction, the elder brother catches up with the younger brother in 24 minutes and runs one more lap than the younger brother:

24x+240=24*(60-x)

x+10=60-x

x=25 younger brother speed of 25 m min.

Let the total number of parts in this batch be x.

The master processes 30 pieces per day, and the apprentice processes 28 pieces per day, and the master completes x 30 + 2 = x 28 2 days earlier than the apprentice

14x+840=15x

x = 840 The total number of parts in this batch is 840.

1.Starting in opposite directions, the sum of the speeds of the older brother and younger brother is 240 4 = 60 m min = 1 m second.

Starting in the same direction, the difference in speed between the older brother and the younger brother is 240 24 = 10 m min = 1 6 m sec.

So the speed of the elder brother is 7 12 meters and seconds, and the speed of the younger brother is 5 12 meters and seconds.

If the unit can be written as meter minutes, then the speed of the older brother and younger brother is 35 meters and 25 meters and minutes, respectively.

2.The master processed 2 more than the apprentice every day, and the total number of more processed was 28 2 = 56, so the number of days processed by the master was 56 2 = 28 days.

The total number of parts is 30 28 = 840.

Solution: Let the younger brother's speed be x meters minutes, and the elder brother's speed be y meters minutes, according to the title:

24y-24x=240

4x+4y=240

Solution: x=25

y=35A: The speed of the younger brother is 25 meters per minute.

2. Solution: Let the number of this batch of parts be x, according to the question:

x÷28-x÷30=2

Solution: x=840

Answer; The total number of parts in this batch is 840.

①240÷24=10

60-10) 2=25 m min.

30*28) (30-28)*2=840 (pieces) or more belongs to the primary school Olympiad method.

Brother: 35 meters min, Brother: 25 m min.

Brother is faster than brother: 240 24 = 10 m minutes.

Brother and brother speed sum: 240 4 = 60 m min.

The total number of parts in this batch is 840.

Master 28 days.

Apprentice for 30 days.

1. The speed of the elder brother is set to x, and the speed of the younger brother is y, then the first time in the same direction, 24x-24y=240m, and the second time in the opposite direction, 4x+4y=240, so we know that x-y=10, x+y=60, x=35, y=25, and the younger brother's speed is 25m minutes.

2. A total of x, then x 30 + 2 = x 28 to get x = 840

Let the speed of the elder brother be x meters per minute, and the speed of the younger brother is y meters per minute, 24x-24y=240

4x+4y=240

Solve systems of equations. Solve x series equations for part work.

x/30—x/28=2

Solving equations in elementary school?

5.The distance from the point of a to the origin on the number line is +3 or -3. and a is less than its opposite. So a is -3. After moving 5 single lengths to the right, it is 2. The opposite number is -2.

The answer is: -2

A is less than its opposite, indicating that it is negative.

The distance from the point of a to the origin is 3, indicating that it is +3 or -3 In summary, a = -3

Move the point to the right by 5 single lengths to get +2

The opposite of the number gives -2
