jimthompson5910 (jim_thompson5910):

any ideas?

OpenStudy (anonymous):

b

OpenStudy (anonymous):

?

jimthompson5910 (jim_thompson5910):

sorry my computer glitched a bit yes it is choice b since -7 < -6 is true

OpenStudy (anonymous):

jimthompson5910 (jim_thompson5910):

how far did you get?

OpenStudy (anonymous):

a or c for the first one

jimthompson5910 (jim_thompson5910):

x > 2 means we're looking for numbers greater than 2

jimthompson5910 (jim_thompson5910):

on the number line that means you shade to the right

OpenStudy (anonymous):

oh

OpenStudy (anonymous):

then i think b or d

OpenStudy (anonymous):

@jim_thompson5910

jimthompson5910 (jim_thompson5910):

is the endpoint closed? or open?

OpenStudy (anonymous):

its opened?

jimthompson5910 (jim_thompson5910):

yes because > has you use an open endpoint that means you exclude the endpoint (in this case, you exclude 2)

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

so for one im c? @jim_thompson5910

OpenStudy (anonymous):

thinking"

jimthompson5910 (jim_thompson5910):

which one?

OpenStudy (anonymous):

the first one that the very top but i gues the second one

jimthompson5910 (jim_thompson5910):

you told me that the endpoint was open

OpenStudy (anonymous):

right so the answer is c? idk

jimthompson5910 (jim_thompson5910):

you're on #4 right?

jimthompson5910 (jim_thompson5910):

or #5?

OpenStudy (anonymous):

4

jimthompson5910 (jim_thompson5910):

notice how C for any of the two has a closed circle

jimthompson5910 (jim_thompson5910):

at the endpoint

OpenStudy (anonymous):

oh yeah D @jim_thompson5910

OpenStudy (anonymous):

@jim_thompson5910

jimthompson5910 (jim_thompson5910):

OpenStudy (anonymous):

i got A

jimthompson5910 (jim_thompson5910):

pay close attention to the inequality sign

OpenStudy (anonymous):

ok

jimthompson5910 (jim_thompson5910):

are we including or excluding the endpoint?

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

or C because its greater

jimthompson5910 (jim_thompson5910):

5 is C because we including the endpoint

OpenStudy (anonymous):
