You can see that the function is constantly equal to 3 if x is less than -2 (included). So, we have
if [/tex] x\leq -2[/tex]
Similarly, the function is constantly 1 if x is less than -2 (excluded). So, we have
if [/tex] x> -2[/tex]
This is true but not for all numbers. Of course you can divide a number by 2 but if it’s an odd number the answer will be a decimal. But for example 24, the two digits are divisible by 2 and so is the original number. But for example 12, the digits aren’t divisible by 2 (the answer is 1.5) but the original number is.
The answer is no i hope this helps (and let me know if you need this explained)
Since the lengths of the segments AD=PD are equal that means that the triangle is an isosceles triangle. This also means that the angles A and P (in the triangle) are equal.
This also means that the angle P' (the one inside the quadrilateral) is equal to:
Now, if we extend the sides DP and CB we notice that the angles P' and Q
are equal
The only way that this angles can be equal is if the line segments DP and CB are parallel, this comes from the fact that two alternate interior angles are equal if and only if the lines are parallel.
