The answer is option
D) r < 5 or r > – 1.
I'm going to graph each inequality below on a number line.
A) r > 5 or r > – 1.

The result is found just by joining those two intervals together. Actually that compound inequality only implies
r > – 1which does not represent all real numbers.
—————
B) r > 5 or r < – 1.

Numbers between – 1 and 5 (including them) are not included in the union, so you don't have all real numbers represented there either.
—————
C) r < 5 or r < – 1.

Numbers that are greater or equal to 5 are not in the union. So it does not represent all real numbers.
—————
D) r < 5 or r > – 1.
Now
all real numbers are included in the union. So this is the right choice.
Answer:
option D) r < 5 or r > – 1.
I hope this helps. =)

Applying the properties of a parallelogram, the values of x and y are: x = 8; y = 20.9
<h3>Properties of a Parallelogram</h3>
- The opposite sides in a parallelogram have the same length.
- Opposite angles are equal.
- Adjacent angles in a parallelogram are supplementary.
4x - 17 = 2x - 1 (equal sides)
4x - 2x = 17 - 1
2x = 16
x = 8
(3y+5) + (6y -13) = 180
9y - 8 = 180
9y = 180 + 8
9y = 188
y = 20.9
Therefore, applying the properties of a parallelogram, the values of x and y are: x = 8; y = 20.9
