Question

9+8<-3 and -2q < 28
what is the solution set of the inequality

Answer 1

null

Answer 2

what

Answer 3

i suck at math

Answer 4

how can 17<-3

Answer 5

thus it must be a null set

Answer 6

what's a null set

Answer 7

it doesn't include any element ucan consider it a dustbin

Answer 8

A. {}
B. { q:-11<q and q>-14}
C. {q:q<-14}
D. {q:-14<q<-11}
E. None of these

Answer 9

thats the answer choices

Answer 10

a

Answer 11

is your question posted correctly? or did you make a typo?

Answer 12

it's posted correct y

Answer 13

ok, then when is: 9+8 < -3 ?

Answer 14

thats why i said it is anull set

Answer 15

you saying what the answer is, and the asker being able to work it out in their own understanding are 2 different things.

Answer 16

so how can i figure it out

Answer 17

by determining when the given statements are true.

one of the given statements is: 9+8 < -3

can this be true?

Answer 18

i know the answer is not A. But it's true

Answer 19

hmm, can you tell me why you believe the answer is not A ?

Answer 20

since 9+8<-3 is never less possible we cant get a solution of this equation thus the answer is a null set which means that no solution exists and is represnted by {} or \[\emptyset \]

Answer 21

you can think of the brackets as representing a container; a box that holds all the possible answers.

option A is simply telling us that the box is empty and that there are no solutions available.

Answer 22

if you have not made a typo in posting the question, and since +8 < -3 is never true; there are no solutions that we can put in the box; and it remains empty.

Answer 23

... 9+8 that is :)

Answer 24

i don't know then this is what my extra credit says

Answer 25

17

Answer 26

17 is never less than -3.

9+8<-3 AND -2q < 28
fasle true ; since one of the parts is always false then the
statement as a whole is false and there are
no solutions that can make it true.

Answer 27

therefore, the empty set should be the correct choice for an enswer

Answer 28

it's D

Answer 29

if its D, then there has to be a typo error in the question itself.

Answer 30

good luck tho ;)

Answer 31

okay

Answer 32

if it has been

q+8<-3 ; then we could have gotten q < -11 so check to make sure that "9" wasnt meant to be a "q" instead

Answer 33

-7<4k+5<33

Answer 34

great work @amistre64
