Question

In set-builder notation, how do you write the solutions of the inequality?
-4 - z *>=* -2

A) {x|x *>=* -2}
B) {x|x *>=* 2}
C) {x|x *<=* -2}
D) {x|x *<=* 2}

Answer 1

\[-4-z \ge-2,-z \ge -2+4,-z \ge 2,z \le -2,z=\left\{ x:x \le-2 \right\}\]

Answer 2

huh ?

Answer 3

@surjithayer

what he/she did here was isolate z. that's the hard part.

{x:x≤−2} means the set of all x such that x is <=-2

Answer 4

C ?

Answer 5

yep
