Identify the solution set of the inequality, using the given replacement set.

B.


{–4, –3.9, 2}


C.


{–10, –4.3}


D.


{–3.9, 2}

Answer 1

You have to make a new set with all the elements in the main list that are less than -4.

{–10, –4.3, –4, –3.9, 2, 6.5}
-10,-4.3...

Answer 2

OH MY GOODNESS. that explains x < –4. thank you thank you thank you.

Answer 3

I guess that's where it ends
{-10,-4.3}

Answer 4

what about -4?

Answer 5

You have to take -4 and plug that into "x<-4"

Ask yourself if it's true. Can any number be less than itself? (no)

Answer 6

oh. that makes sense
