Question

Which values of k are solutions to the inequality |-k-2|<18? Check all that apply
-40

Answer 1

Answer:

any number except -20

Step-by-step explanation:

$|-k-2|<18$

$-k-2<18$                              $-k-2>18$

$-k<18+2$                               $-k>18+2$

$-k<20$                                      $-k>20$

Multiply by -1 to make the k positive. This will alter all the terms which means 20 will become negative. NOTE: When multiplying or dividing by negative numbers, the inequaliy sign flips.

$k>-20$                                           $k<-20$

k must be either greater than -20 but not including it or fewer than -20 but not including it; therefore, any number between negative infinity and -21 and -19 and postive infinity
