Question

При каком значении x значение функции y(x)=3-4xбудет равно-13​

Answer 1

Значение функции y(x)=3-4x будет равно -13 при x:

-13=3-4x

-13-3=-4x

-16=-4x

x=4

При значении x=4 значение функции y(x)=3-4x будет равно-13​.

Ответ: 4

Answer 2

To find the value of x when the function y(x) = 3 - 4x is equal to -13, we need to set y(x) equal to -13 and then solve for x.

Given: y(x) = 3 - 4x

Setting y(x) equal to -13:

-13 = 3 - 4x

Now, let's solve for x:

Add 4x to both sides:

4x - 13 = 3

Add 13 to both sides:

4x = 3 + 13 4x = 16

Finally, divide both sides by 4 to isolate x:

x = 16 / 4 x = 4

So, when x is equal to 4, the value of the function y(x) will be -13.
