Question

Для линейной функции y=-0.5x+3 найдите значение x при y=-2

Answer 1

-2 = -0,5x + 3
0,5x = 5
x = 10

Answer 2

To find the value of x when y = -2 for the linear function y = -0.5x + 3, we can substitute y with -2 and then solve for x.

Given: y = -0.5x + 3 Let y = -2

-2 = -0.5x + 3

Now, we need to solve for x. Let's isolate x on one side of the equation:

-0.5x = -2 - 3 -0.5x = -5

Now, divide both sides by -0.5 to solve for x:

x = -5 / -0.5 x = 10

So, the value of x when y = -2 for the linear function y = -0.5x + 3 is x = 10.
