Question

На координатном луче отмечены точки А (1,21), В и С. Известно, что координаты точки В на 5 больше, чем координата точки А, отрезок ВС в 2 раза длиннее отрезка АВ, а точка С расположена правее точки В. Найдите координату точки С. Помогите,пожалуйста!!!

Answer 1

Точка В- 1,21+5=6,51
Отрезок АВ- 5, а ВС- 5*2=10
Точка С- 6,21+10= 16,21

Answer 2

Problem Analysis

We are given three points on a coordinate ray: A(1,21), B, and C. We know that the x-coordinate of point B is 5 more than the x-coordinate of point A. The length of segment BC is twice the length of segment AB. Point C is located to the right of point B. We need to find the coordinates of point C.

Solution

Let's break down the information given and solve the problem step by step.

1. The x-coordinate of point B is 5 more than the x-coordinate of point A. - Let's assume the x-coordinate of point A is x. Therefore, the x-coordinate of point B is x + 5.

2. The length of segment BC is twice the length of segment AB. - Let's assume the length of segment AB is d. Therefore, the length of segment BC is 2d.

3. Point C is located to the right of point B. - Since point C is located to the right of point B, the x-coordinate of point C must be greater than the x-coordinate of point B.

Now, let's find the coordinates of point C.

Finding the Coordinates of Point C

1. The x-coordinate of point B is x + 5. 2. The length of segment BC is 2d. 3. The x-coordinate of point C is greater than the x-coordinate of point B.

Since we don't have the exact values of x and d, we cannot determine the exact coordinates of point C. However, we can express the coordinates of point C in terms of x and d.

Let's assume the y-coordinate of point C is y.

Therefore, the coordinates of point C can be expressed as (x + 5, y).

Conclusion

In conclusion, the coordinates of point C can be expressed as (x + 5, y), where x is the x-coordinate of point A and y is the y-coordinate of point C. Unfortunately, without more information or specific values for x and d, we cannot determine the exact coordinates of point C.
