Answer:
(a) x < 0
(b) y ≥ 0
(c) q ≤ π
Explanation:
Symbol notation
- < means "less than".
- > means "greater than".
- ≤ means "less than or equal to".
- ≥ means "greater than or equal to".
- = means "equals".
A negative real number is any real number that is less than zero.
A positive real number is any real number that is greater than zero.
Zero is neither positive nor negative.
(a) x is negative → x < 0.
If x is negative, then x is less than zero.
(b) y is nonnegative → y ≥ 0.
Nonnegative means not negative.
Therefore, y is more than or equal to zero.
(c) q is less than or equal to π → q ≤ π.
