Question

Функцция:y=2x-15.значение x, при которой y=-5

Answer 1

Выполнение задания сводится к решению уравнения:

$2x - 15 = -5;\\ 2x = 15 - 5;\\ 2x=10;\\ x=5.$

Ответ: 5.

Answer 2

подставляем -5 вместо у

2х-15=-5

2х=10

х=5

Answer 3

To find the value of x when y is equal to -5 in the equation y = 2x - 15, we can substitute y with -5 and solve for x:

-5 = 2x - 15

To isolate x, let's first add 15 to both sides of the equation:

-5 + 15 = 2x

Now, simplify:

10 = 2x

Finally, to find the value of x, divide both sides by 2:

x = 10 / 2 x = 5

So, when y is equal to -5, the value of x is 5.
