13. In set-builder notation, how do you write the solutions of the inequality?

–2 – x ≥ – 1 (1 point)
{x | x ≤ 1}
{x | x ≥ 1}
{x | x ≥ –1}
{x | x ≤ –1}
14. What are all the subsets of the set?

{–1, 9} (1 point)
Ø, {–1}, {9}
{–1}, {9}, {–1, 9}
Ø, {–1}, {9}, {–1, 9}
{–1}, {9}

1. Just simplify the inequality u will get {X/x<=-1}
2.To find the subsets 2n( 2the power of n where n is number of elements)i.e n=2 so the subsets are 4 therefore Ans is 3rd one!!
