Question

Y=-2x+5 значение функции -3

Answer 1

Объяснение:

-2х+5= -3

-2х= -3-5

-2х= -8

х= 8:2

х= 4

Answer 2

To find the value of x when the function y equals -3, you can substitute -3 for y in the equation and solve for x.

Given the equation: y = -2x + 5

Substituting y = -3:

-3 = -2x + 5

To isolate x, we can subtract 5 from both sides of the equation:

-3 - 5 = -2x

-8 = -2x

To solve for x, divide both sides of the equation by -2:

-8 / -2 = x

x = 4

Therefore, when y equals -3, the value of x in the function y = -2x + 5 is 4.
