Use DeMorgan's Laws to negate the following expressions. Be sure to complete your negation through to the "simplified" negation (do not just put "!" in front of the original expression).

Example: p || q --> !p && !q

(Note: !(p || q) is not an acceptable alternative)

a) x >= 5 && x <= 10

b) x == 0 || x >= 100

c) !x
