Question

Функция задана формулой y= 2/x ; Найдите x , если y равен -8;-3/2;1/4;6

Answer 1

y= 2/x ;
Найдите x , если y = -8; -3/2; 1/4; 6
1) - 8 = 2/х, ⇒ х = -1/4
2) -3/2 = 2/х, х = -4/3
3) 1/4 = 2/х, ⇒ х = 8
4) 6= 2/х,⇒ х = 1/3

Answer 2

To find the value of x for different given values of y in the function y = 2/x, we can simply substitute the values of y into the equation and solve for x. Let's go through each given value of y:

1. For y = -8: -8 = 2/x To find x, we can rearrange the equation: x = 2 / (-8) = -1/4

2. For y = -3/2: -3/2 = 2/x x = 2 / (-3/2) = -4/3

3. For y = 1/4: 1/4 = 2/x x = 2 / (1/4) = 8

4. For y = 6: 6 = 2/x x = 2 / 6 = 1/3

So, the corresponding values of x for the given y values are: x = -1/4, -4/3, 8, and 1/3.
