Question

Функция задана формулой у=5х+6.Найдите значения аргумента ,при котором значение функции равно -3

Answer 1

подставляем значение: 5x+6= -3; 5x= -3-6; 5x= -9; x=(-9)/5= -1,8. Ответ: x= -1,8. да.

Answer 2

To find the value of the argument (x) when the value of the function (y) is equal to -3, we can set up the equation and solve for x.

Given the function: y = 5x + 6

We want to find the value of x when y = -3.

So, we set y = -3 and solve for x:

-3 = 5x + 6

To solve for x, we'll isolate x on one side of the equation:

5x = -3 - 6 5x = -9

Now, divide both sides by 5 to solve for x:

x = -9 / 5

So, the value of the argument (x) when the value of the function (y) is -3 is:

x = -9 / 5
