how do i graph this?

- saifoo.khan

|dw:1332341729422:dw|

- saifoo.khan

As you can see, "x" is greater than -3.

- mysesshou

And also not including -3 because of the circle. :)

- anonymous

negative a open circle and postive a closed one

- saifoo.khan

Oh right.

- anonymous

i got this one x-4<(with line under it) 3. im graphing those two on same line

- mysesshou

"greater than equal to " or "equals" is a closed circle, including the number at the circle.
"greater than" means open circle because it is only up to the number not including

- anonymous

> is greater than or less than?

- mysesshou

depends where the numbers and x are.
for x > -3 it is read x is greater than -3.
Imagine it like an alligator mouth. it wants to eat the most, so the x is the greater than.

- mysesshou

if it was written x < -3 then it is "x is less than -3" because the alligator is going for the -3 then it is read as the opposite for the "x is ____"

- mysesshou

not sure i understand this Q:
i got this one x-4<(with line under it) 3. im graphing those two on same line

- mysesshou

oooohh.

- mysesshou

\[x-4 \le 3\] ?

- anonymous

yeaa

- mysesshou

ok. add 4 to both sides.

- mysesshou

\[x \le 7\]

- mysesshou

you're adding this to the previous graph?

- anonymous

yes

- mysesshou

\[x >-3\] and
\[x \le 7\]
what you do is open circle for -3 because it is not including it. filled in circle for the 7 because it is including it.
you can rewrite it to
\[-3

lol horrible drawling

- mysesshou

Yep. that works !
Yeah, it is difficult to draw on this site. :)

- anonymous

i have to do this for 3 more prblems :/

- mysesshou

\[\le\] and \[\ge\] mean closed circles because it is also the equal to . Less than or equal to. .greater than or equal to.
the < or > are only less than or greater than, so those are open circles.
if you are just subtracting or adding a number you can just pretend the symbol is a = symbol. also for positive multiplication and division.
for multiplying or dividing by negative numbers you have to flip the sign over.

- anonymous

thank you, I remember this stuff a very long time ago but i have forgotten.

- mysesshou

Yep, it is the little things to remember :)
youre welcome!

\[\ge\]

- anonymous

x + 5 \[\ge\] 2x + 1 and -4x < -8

- mysesshou

\[x+5 \ge 2x+1\]
and \[-4x<-8\]
?

- mysesshou

brb

- mysesshou

ok. for that first one.
\[x+5 \ge 2x+1\]
first, subtract 1 from both sides
\[x+4 \ge 2x\]
then subtract x from both sides
\[4 \ge x\]

- mysesshou

for the second one,
\[−4x<−8\]
divide by -4 both sides. dont forget to flip the symbol
\[x>2\]

- mysesshou

flip the x>2 to be 2
