Question

-(3,3a+1,2b)+(0,7b-1,7a)

Answer 1

Ответ:

Пошаговое объяснение:

=-3.3а-1.2b+0.7b-1.7a=-5a-0.5b

Answer 2

Ответ:

-5а - 0,5b или -(5а + 0,5b) или -0,5(10а + b)

Пошаговое объяснение:

-(3,3a + 1,2b) + (0,7b - 1,7a) = -3,3а -1,2b + 0,7b - 1,7а =

-5а - 0,5b = -(5а+0,5b) = -0,5(10а + b)

Все три ответа верные.

Answer 3

To perform the operation of adding the vectors -(3, 3a + 1, 2b) and (0, 7b - 1, 7a), we need to add the corresponding components of the two vectors. Adding two vectors involves adding their corresponding x, y, and z components separately. So, the result of the addition is:

X-component: -3 + 0 = -3 Y-component: (3a + 1) + (7b - 1) = 3a + 7b Z-component: 2b - 7a

Therefore, the sum of the two vectors -(3, 3a + 1, 2b) and (0, 7b - 1, 7a) is (-3, 3a + 7b, 2b - 7a).
