Answer 9

ok I'm looking at your last question @goopyfish908

do you see how @Kkutie7 went from
\[\Large \frac{x}{-2}-8\le-2\]
to
\[\Large x\ge-12\]
???

Answer 10

step 1. we need x by itself
step 2. multiply -2 throughout the equation.
step 3. ???????????
step 4. ??????????

Answer 11

yes, sur

Answer 12

how would you graph
\[\Large x\ge-12\]
on a number line

Answer 13

i dont know how to write it out on here, but yes sur

Answer 14

you could draw it out using the draw button???

Answer 15

you can describe it using words


would you have an open circle? or closed circle? where would this circle be?
would you shade to the left? or to the right?

Answer 16

drawing it out works as well

Answer 17

like draw on microsoft paint or some paint program and then attach the file to here so we can see the number line...that can work as well :)

Answer 18

ok. hang on

Answer 19

this?

Answer 20

close but since we have a \[ \huge \geq\] sign it means closed circle.

Answer 21

here's a good example showing all the possibilities

notice the > means shade to the right
if you have an under line under the >, then the endpoint is a closed circle

Answer 22

oh, i thought it was the oposite

Answer 23

\[\huge > < \] means open circle
\[\huge \geq \leq \] means close circle

Answer 24

ok
