The second one isn't an inequality!
OpenStudy (anonymous):
its an expression
OpenStudy (anonymous):
i mean < with the line under
OpenStudy (anonymous):
its like <_
OpenStudy (slaaibak):
\[\le\]

ya but its only 1 inequality right?
OpenStudy (kainui):
\[x-5y>-7\]\[3x + 4y \leβ8\]
Is this your question?
OpenStudy (anonymous):
YES THATS MY QUESTION
OpenStudy (anonymous):
:D
OpenStudy (anonymous):
I DONT REMEMBER THIS

would it be x<-8/9
yβ€2/9
OpenStudy (anonymous):
doh every 1 went away
OpenStudy (anonymous):
wait lemme check myself ok xD
OpenStudy (anonymous):
HAH OKAY:)
OpenStudy (anonymous):
THERE SUPPOSE TO BE POINTS

a (β1, β1)
b (β2, 4)
c (3, β8)
d (4, 5)
OpenStudy (anonymous):
lol good thing i waitedi was wrong :D
OpenStudy (anonymous):
can you help me though?
OpenStudy (anonymous):
everytime i think its a race to get the answer thats y :P
OpenStudy (anonymous):
ohh

ok
OpenStudy (anonymous):
thanks
OpenStudy (anonymous):
you mean on a coordinate plane?
OpenStudy (anonymous):
yeah
OpenStudy (anonymous):
i think

those are the answers i put up top i just cant figure it out ive been on it for like 17 minutes lol
OpenStudy (anonymous):
okies much different anser than
OpenStudy (anonymous):
then you would also have to specify graphing also :P
OpenStudy (anonymous):
do you know how to put things in slop intercept form?
OpenStudy (anonymous):
i forgot

OpenStudy (anonymous):
is y=mx+b ?
OpenStudy (anonymous):
yup
OpenStudy (anonymous):
do so to the equations (inequalities)
OpenStudy (anonymous):
HUH? LOL
OpenStudy (anonymous):
did i say something wrong again? :P

inequalities are almost the same as equations just that they have the <, > sign
OpenStudy (anonymous):
when you divide, multiply by a negative number the signs < (for example) switches to >
OpenStudy (anonymous):
YEAH YOU LOST ME LOL I HAVE A BRAIN FART
OpenStudy (anonymous):
for the first
1x-5y>-7 it would equal ?
OpenStudy (anonymous):
so you try :D

i mean to put it in slope intercept form what would it look like
OpenStudy (anonymous):
ahh idk i give up lol
OpenStudy (anonymous):
okies slope intercept form as you said looks somewhat like this
y=mx+b (which is correct)
right?
OpenStudy (anonymous):
and you have
x-5y > -7
OpenStudy (anonymous):
yeah?

umm do you know how to put simple equations into slope intercept form?
OpenStudy (anonymous):
i dont remember i prob do but i dont remember lol and i have 2 minutes left on my time to answer the QUESTION!
OpenStudy (anonymous):
y <1/5x+7
OpenStudy (anonymous):
that doesnt match any of the answers though
OpenStudy (anonymous):
yβ€-3x/4-2

OpenStudy (anonymous):
if you know how to graph it should be very easy
OpenStudy (anonymous):
the time passed its too late anyways lol
OpenStudy (anonymous):
thanks though
OpenStudy (anonymous):
:)

oh and what was the real answer anyway haha ?
OpenStudy (anonymous):
inequalities cover a range really :P
OpenStudy (anonymous):
i dont really know about a specific point
OpenStudy (anonymous):
unless its from the point you are graphing from
OpenStudy (anonymous):
you know how to graph inequalities right?
