Question

Функция задана формулой y=2x-10.Найдите значение x,при котором функция принимает значение,равное 8.

Answer 1

Y = 2x - 10
8 = 2x - 10
2x = 18
x = 9 
При x = 9 значение функции равно 8

Answer 2

To find the value of x when the function takes the value 8, you can simply set y (the function output) equal to 8 and solve for x. Here's how you can do it:

Given function: y = 2x - 10

Let y = 8:

8 = 2x - 10

Now, isolate x:

2x = 8 + 10

2x = 18

x = 18 / 2

x = 9

So, when the function y = 2x - 10 takes the value 8, the value of x is 9.
