Question

Функция задана формулой у=4х-30. Определите значение значение х, при котором у=-6.

Answer 1

Ответ: -9

Пошаговое объяснение: подставим вместо у -6 , тогда:

-6 = 4х - 30

-4х = 6 + 30

-4х = 36

х = 36/(-4)

х = -9

Answer 2

To find the value of x when y = -6 in the function y = 4x - 30, you need to set y equal to -6 and solve for x. So, the equation becomes:

-6 = 4x - 30

Now, you want to isolate x on one side of the equation, so add 30 to both sides:

-6 + 30 = 4x - 30 + 30 24 = 4x

Finally, divide both sides by 4 to solve for x:

x = 24 / 4 x = 6

Therefore, the value of x when y = -6 is x = 6.
