Question

Существует ли такое значение аргумента x, при котором значения функции y=2-5x и y=-12x равны?

Answer 1

y=2-5x и y=-12x

2 - 5x= - 12x

-5x+12x= - 2

7x= - 2  /:7

x= - 2/7

Answer 2

To find the value of the argument "x" for which the two functions are equal, we need to set the expressions for "y" from both functions equal to each other and solve for "x". So, we have:

2 - 5x = -12x

To find "x," we'll solve this equation:

2 + 12x = 5x (added 12x to both sides) 2 = 5x - 12x (combined the "x" terms on the right side) 2 = -7x (combined "x" terms)

Now, we need to isolate "x" on one side of the equation. To do that, we'll divide both sides by -7:

x = 2 / (-7)

x = -2/7

So, the value of "x" at which the two functions y = 2 - 5x and y = -12x are equal is x = -2/7.
