Question

Pascal abc y=x/2 x>25 x+4 x<25

Answer 1

program task31057170;

var

 x: integer;

 y: real;

begin

 Writeln('ВВЕДИТЕ X: ');

 Readln(x);

 if x > 25 then

   y := x / 2

 else if x < 25 then

   y := x + 4

 else Writeln('Error: x = 25!');

 Writeln('Y = ', y);

end.

Answer 2

It appears that you've provided some equations, but they seem to be incomplete. It seems like you want to define a function based on two different cases, one for when x is greater than 25, and another for when x is less than 25. However, the function is not entirely defined.

Let's try to clarify and complete the function based on the information provided:

1. For x > 25: In this case, the equation is y = x/2.

2. For x < 25: In this case, the equation is y = x + 4.

If we put these two cases together, the complete piecewise function would look like this:

y = { x/2 if x > 25, x + 4 if x < 25 }

This function represents a straight line with a slope of 1/2 when x is greater than 25, and a straight line with a slope of 1 when x is less than 25. The function changes its behavior at x = 25, where the two parts are connected.
