List the elements of the following set :

{x : 4 - 2x > -6, x ∈ Z}

State which of the following sets are finite and which are infinite :

(i) A = {x : x ∈ Z and x < 10}

(ii) B = {x : x ∈ W and 5x - 3 ≤ 20}

(iii) P = {y : y = 3x - 2, x ∈ N and x > 5}

(iv) M = ${\Big{x:x = \dfrac{3}{n}; n ∈ W \text{ and } 6 < n ≤ 15\Big}}$

Find which of the following sets are empty :

(i) The set of points of intersection of two parallel lines.

(ii) A = {x : x ∈ N and 5 < x ≤ 6}.

(iii) B {x : x² + 4 = 0 and x ∈ N}.

(iv) C = {even numbers between 6 and 10}.

(v) D = {prime numbers between 7 and 11}.

Are the sets A = {4, 5, 6} and
B = {x : x² - 5x - 6 = 0} disjoint ?
