Answer 1

Ответ:

1) (x+2,3)-(x+7,8)=x-x+2.3-7.8=-5.5

2) -(7,2-y)+(-y+1,6)=y-y-7.2+1.6=-5.6

Answer 2

Ответ:

1) -5,5;

2) -5,6.

Пошаговое объяснение:

1)

(х + 2,3) - (х + 7,8)

х + 2,3 - х - 7,8

2,3 - 7,8

-5,5

2)

-(7,2 - у) + (у + 1,6)

-7,2 - у + у + 1,6

-7,2 + 1,6

-5,6

Answer 3

1. To subtract the vectors (x+2, 3) and (x+7, 8), you need to subtract the corresponding components of the vectors:

(x+2, 3) - (x+7, 8) = (x+2 - (x+7), 3 - 8) = (x + 2 - x - 7, -5) = (-5, -5)

So the result of subtracting the vectors (x+2, 3) and (x+7, 8) is (-5, -5).

2. To subtract the vectors -(7, 2-y) and (-y+1, 6), you need to negate each component of the first vector and then subtract the corresponding components:

-(7, 2-y) + (-y+1, 6) = (-7, y-2) + (-y+1, 6) = (-7 + (-y+1), y-2 + 6) = (-y-6, y+4)

So the result of subtracting the vectors -(7, 2-y) and (-y+1, 6) is (-y-6, y+4).
