Question

Функция задана формула y=2(x-4) функция равна 0,4

Answer 1

у=2(х-4)

у=0,4

2(х-4)=0,4

х-4=0,2

х=4,2

Ответ: при х=4,2   у=0,4.

Answer 2

To find the value of x when y equals 0.4 in the given function y = 2(x-4), you can set y to 0.4 and solve for x.

Given: y = 0.4 y = 2(x-4)

Substitute y with 0.4: 0.4 = 2(x-4)

Now, solve for x: 0.4 = 2x - 8

Add 8 to both sides: 0.4 + 8 = 2x

8.4 = 2x

Now, divide both sides by 2: x = 8.4 / 2 x = 4.2

So, when y = 0.4, the value of x is 4.2.
