    Please show all steps. Thank you.

    Express the set using set- builder notation. Use inequality notation to express the condition x must meet in order to be a member of the set.

    1. A= { 12, 13, 14, 15, 16,...}

    2. A= { 600, 601, 602,...,6000}

    3. Calculate the number of subsets and the number of proper subsets for the set.

    1. the set of natural numbers less than 10

    2. { x / x is a day of the week}

    Dear student, see below for the solution to this problem.

    1. A= {12, 13, 14, 15, 16, ...}
    Observe that the elements of set A are natural numbers more than or equal to 12. So, we can write it as  
    A= {xN/ x≥12}

    2. A= {600, 601, 602, ... ...
