Question

Найдите значение аргумента при котором значение функции y=2x+7 равно -9

Answer 1

Ответ: -8

Объяснение:

у=2х+7

Если у= -9, то   2х+7= -9;  2х= -9-7;  2х= -16;  х= -16:2;   х= -8.

Answer 2

To find the value of the argument (x) for which the function y = 2x + 7 is equal to -9, we simply need to set y equal to -9 and solve for x.

Given: y = 2x + 7

Setting y = -9:

-9 = 2x + 7

Now, let's solve for x:

Subtract 7 from both sides:

-9 - 7 = 2x

-16 = 2x

Divide both sides by 2:

x = -16 / 2

x = -8

So, the value of the argument (x) at which the function y = 2x + 7 is equal to -9 is x = -8.
