Question

Вектор AB (-4;0) B (-2;7) Найти координаты A

Answer 1

A=(2;7)

Так как:

AB=(-4;0)

B=(-2;7)

Если AB= (x2-x1;y2-y1)

(-2-x1=-4;y1-7=0)

x1=2

y1=7

Answer 2

помоему (2;7) но не думаю что правильно

Answer 3

To find the coordinates of point A, we can use the vector AB and point B. The vector AB represents the displacement from point A to point B. So, to get back to point A from point B, we need to reverse the direction of the vector AB.

The coordinates of A can be obtained by subtracting the components of vector AB from the coordinates of point B:

Let's do the calculations:

Vector AB = (xB - xA, yB - yA)

Given vector AB = (-4, 0) and point B (xB, yB) = (-2, 7)

To find point A (xA, yA):

xA = xB - (-4) = -2 - (-4) = -2 + 4 = 2 yA = yB - 0 = 7 - 0 = 7

So, the coordinates of point A are (2, 7).
