Question

Функция задана уравнением y=-2/7x.Найдите значение аргумента,при котором значение функции равно 14

Answer 1

$-\frac{2}{7}x=14\ /:(-\frac{2}{7})\\\\x=-49$

Ответ: - 49

Answer 2

To find the value of the argument (x) when the function's value (y) is equal to 14, we can set up the equation and solve for x.

Given the function: y = -2/7x

We know that when y = 14, the equation becomes: 14 = -2/7x

Now, we need to isolate x to solve for its value. To do that, we'll follow these steps:

Step 1: Multiply both sides of the equation by -7 (to get rid of the fraction). -7 * 14 = -2x

Step 2: Simplify the equation. -98 = -2x

Step 3: Divide both sides by -2 to solve for x. x = -98 / -2

Step 4: Calculate the value of x. x = 49

Therefore, the value of the argument (x) when the value of the function (y) is equal to 14 is x = 49.
