It would have been nice if u could of not gotten the answers off google.

  • anonymous
So, buddy, it was already solved
nubeer
  • nubeer
you have to make "x" isolate. so u can do that by adding 3 on both sides.
dmezzullo
  • dmezzullo
Can one of u guys help with the graphs?

  • nubeer
when u solve u will get x> -6, it means the value of x is greater then -6 so first you draw a number line

Sir, the process is, 1) Click on the Link, 2) See the graph, 3) Investigate it, 4) Ask Doubts, 5) Be free, Check it!
nubeer
  • nubeer
now make a circle at the value we found.. |dw:1363695185074:dw|
nubeer
  • nubeer
|dw:1363695217104:dw|
dmezzullo
  • dmezzullo
Ok, lemme try the next one
nubeer
  • nubeer
sure.. if still any confusion just ask me out
dmezzullo
  • dmezzullo
Ok, u tell me if it is wrong
nubeer
  • nubeer
ok
dmezzullo
  • dmezzullo
Wait imma do #3 bc im not sure wut to do for #2
dmezzullo
  • dmezzullo
|dw:1363695538390:dw|
nubeer
  • nubeer
yup. perfectly fine.
nubeer
  • nubeer
what's hard with 2?
dmezzullo
  • dmezzullo
it has the line under the > so idk if tht changes anything
nubeer
  • nubeer
yes it changed something very little.. you have to put a dot rather then a circle.
nubeer
  • nubeer
but a bold dot.
dmezzullo
  • dmezzullo
oh ok lemme try it then
dmezzullo
  • dmezzullo
wait im confused wince it is +6 would i go to 5 next or 7
nubeer
  • nubeer
well answer u got is x greater then equal to +6 so u have to point the arrow towards the greater values then 6.
dmezzullo
  • dmezzullo
ok tyvm
dmezzullo
  • dmezzullo
|dw:1363695994614:dw|
dmezzullo
  • dmezzullo
Is that right?
nubeer

yes it is right.
dmezzullo
  • dmezzullo
okie

  • dmezzullo
|dw:1363696204568:dw|
nubeer
  • nubeer
hmm which question is this one?
dmezzullo
  • dmezzullo
#4
dmezzullo
  • dmezzullo
no it should be 3
dmezzullo
  • dmezzullo
on the graph shouldnt it?
nubeer
  • nubeer
for question for u got x< -3 so arrow should point towards the value less then -3
nubeer
  • nubeer
oops for question 4
nubeer
  • nubeer
damn sorry x<3
dmezzullo
  • dmezzullo
oh lemme redraw it
dmezzullo
  • dmezzullo
|dw:1363696430998:dw|
nubeer
  • nubeer
yup .. correct .. this was #4
dmezzullo
  • dmezzullo
|dw:1363696529947:dw|
nubeer
  • nubeer
yup correct bro..
dmezzullo
  • dmezzullo
tyvm now 2 more things if u dont mind sir
nubeer
  • nubeer
not at all.
dmezzullo
  • dmezzullo
Explain, in complete sentences, when you would use an open circle or a closed circle, and when you would shade to the right or left, to graph an inequality on the number line.
nubeer
  • nubeer
hmm well bro i can tell u in simple words or explain u in easy words .. so u just have to put urself in proper sentences .. is that ok?
dmezzullo
  • dmezzullo
Yes tht fine
nubeer
  • nubeer
ok first.. open circle is when we get < or > sign in our final answer.. same like in question #1 and closed circle when we get answer < or > having lines under, as u can see in the answer of #2 question..
nubeer
  • nubeer
we shade to left when x< (any value) |dw:1363697010246:dw| like this for #4
nubeer
  • nubeer
and we shade towards right when we get x> (any value) for example if x> 6 we will shade all the part forward from the point 6.
nubeer
  • nubeer
got it bro?
dmezzullo
  • dmezzullo
Oh ok.
dmezzullo
  • dmezzullo
1 more q.
dmezzullo
  • dmezzullo
Describe a real life scenario where inequalities are used and state the inequality.
dmezzullo
  • dmezzullo
So the senario would be: Teens in florida have to be at least 15 or older to get their learners permit to drive.
dmezzullo
  • dmezzullo
But i am not totally sure wut the graph would look like.
nubeer
  • nubeer
hmm well if we say x is the age.. for learner permit x >(line under) 15
dmezzullo
  • dmezzullo
|dw:1363697462126:dw|
nubeer
  • nubeer
yes this is the in eguality
nubeer
  • nubeer
now draw the graph which is a number line and label it
dmezzullo
  • dmezzullo
wut u mean?
nubeer
  • nubeer
umm .. i mean draw a number line.. just the line with numbers u need.?
anonymous
  • anonymous
just remember if there is an equal sign in the inequality, it has a closed circle.
nubeer
  • nubeer
ohh lol we dont need to graph this question.. or do we?
anonymous
  • anonymous
we can if you want to....it is good practice
dmezzullo
  • dmezzullo
I believe we dont
nubeer
  • nubeer
ok then just write inequality with the scenario you told.. and that's it i guess
dmezzullo
  • dmezzullo
ok ty soooo very much how can i ever repay u?
anonymous
  • anonymous
|dw:1363697698821:dw|
nubeer
  • nubeer
hahah bro.. lol u don't need to repay at all :)
dmezzullo
  • dmezzullo
Ok that was alot of work i will write u a testimonial
nubeer
  • nubeer
Sweet... :)
