Question

(-1,2а+3)-(1,6-2,5а)

Answer 1

Ответ: -3

Объяснение:

1+2а-6+5а+5-3а=4а = 4*(-3/4)=-3

Answer 2

To subtract the vectors (-1, 2a + 3) and (1, 6 - 2.5a), you need to subtract their corresponding components.

Subtract the x-components: -1 - 1 = -2

Subtract the y-components: (2a + 3) - (6 - 2.5a) = 2a + 3 - 6 + 2.5a = (2a + 2.5a) + (3 - 6) = 4.5a - 3

So, the result of subtracting these two vectors is (-2, 4.5a - 3).
