Question

Функция задана формулой y=1,5-3x.при каком значении аргумента значении функции равно -4,5

Answer 1

-4.5=1.5-3x
3x=6
x=2
Ответ:х=2

Answer 2

To find the value of the argument (x) for which the function's value (y) is equal to -4.5, you can set up the equation and solve for x.

The function is given by: y = 1.5 - 3x

We want to find the value of x when y = -4.5.

So, we set up the equation: -4.5 = 1.5 - 3x

Now, let's solve for x:

Add 3x to both sides to isolate the term with x:

-4.5 + 3x = 1.5

Next, subtract 1.5 from both sides to get x alone:

3x = 1.5 - 4.5

3x = -3

Finally, divide both sides by 3 to solve for x:

x = -3 / 3

x = -1

Therefore, when the value of the argument (x) is -1, the value of the function (y) is -4.5.
