Question

Даны точки А(-15,3) и В(7,5). Известно, что точка М - середина отрезка АВ, а точка Е - середина отрезка АМ. Найдите координату точки Е

Answer 1

Ответ:

-5,7

Пошаговое объяснение:

1)7,5 - ( 7,5 + 15,3)/ =7,5 - 22,8/2 =7,5 - 11,4 = -3,9 - точка M

2)-(15,3-3,9)/2 = - 11,4/2 = - 5,7 - точка E

Answer 2

To find the coordinates of point E, which is the midpoint of segment AM, we can use the midpoint formula. The midpoint formula states that the coordinates of the midpoint between two points (x1, y1) and (x2, y2) are given by:

Midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)

Let's calculate the coordinates of point M first, which is the midpoint of segment AB.

Coordinates of point A: (-15, 3) Coordinates of point B: (7, 5)

Midpoint M = ((-15 + 7) / 2, (3 + 5) / 2) Midpoint M = (-8 / 2, 8 / 2) Midpoint M = (-4, 4)

Now, we'll find the coordinates of point E, which is the midpoint of segment AM.

Coordinates of point A: (-15, 3) Coordinates of point M: (-4, 4)

Midpoint E = ((-15 + (-4)) / 2, (3 + 4) / 2) Midpoint E = ((-19) / 2, 7 / 2) Midpoint E = (-9.5, 3.5)

So, the coordinates of point E are (-9.5, 3.5).
