Question

Дана функция y=b−5. При каких значениях b значение функции равно 7?

Answer 1

При b=12
Объяснение y=12-5
y=7

Answer 2

To find the values of 'b' for which the function value y = b - 5 is equal to 7, we can set up the equation and solve for 'b'.

The equation is: b - 5 = 7

Now, let's solve for 'b':

Add 5 to both sides of the equation to isolate 'b': b = 7 + 5

b = 12

So, when 'b' is equal to 12, the value of the function is y = b - 5 = 12 - 5 = 7.
