Question

Функция задана формулой у=3х-8. найдите значение аргумента ,при котором значение функции равно 7

Answer 1

ПОДСТАВЛЯЕМ ЗНАЧЕНИЕ: 3x-8=7, 3x=7+8; 3x=15; x=15/3=5. Ответ:  x=5.

Answer 2

To find the value of the argument (x) when the value of the function (y) is equal to 7, we can set up the equation and solve for x.

The function is given as: y = 3x - 8

We want to find the value of x when y = 7, so we can set up the equation as follows: 7 = 3x - 8

Now, let's solve for x: Add 8 to both sides to isolate 3x: 7 + 8 = 3x 15 = 3x

Next, divide both sides by 3 to solve for x: x = 15 / 3 x = 5

So, the value of the argument (x) when the value of the function (y) is equal to 7 is x = 5.
