Question

HELP ME PLEASE True or false: z=−5 is a solution to the inequality −2|z−3|<−20.

Answer 1

your question:

True or false: z=−5 is a solution to the inequality −2|z−3|<−20.

answer:

-2|z-3|<-20

-------. -----

-2 -2

|z-3|<10

equation 1: equation 2:

z-3<10. z-3>-10

z<13 z>-13

So false, z=-5 is not a solution to the inequality.

hope this helps, have a great day! :)
