Question

Дана функция y=−b+5. При каких значениях b значение функции равно −3? b= .

Answer 1

Ответ:

в=8

Объяснение:

подставляем -3=-в+5, -в=-8, в=8 ответ

Answer 2

To find the value of b when the function y = -b + 5 is equal to -3, we can substitute -3 for y in the equation and solve for b.

-3 = -b + 5

To isolate b, we can subtract 5 from both sides of the equation:

-3 - 5 = -b

-8 = -b

Finally, to solve for b, we need to multiply both sides of the equation by -1 to get a positive value for b:

8 = b

Therefore, when b = 8, the value of the function y = -b + 5 is equal to -3.
