stop pretending , put up your questions now
hahaha... no im not, seriously i cant find it :(
question?
well, i guess i will just work on something else in math, i will do that when i find it :P
okay next science
that powerpoint? i am going to do that tonight :)
huh
hehe.. yes :)
here it is :P
wait a sec :)
sure :D
okay.. :P
haha this is funny :D
lol i am editing it, there are some grammatical mistakes, like in third slide, there should be comma after well
sure, edit it the way you like :)
yea yea :D
:)
here is your edited one, it is brilliant and indeed you are genius, just a few minor changes are there
oh thanks! :D
first read it
and find the places where i have done editing
yes i can see some :D
now maths lol
@LonelyandForgotten finally no maths, okay great
yep, no maths today :P
okay
can you help with ordered pairs? :/ thats easyy stuff, i cant do that :D
post your question please
can *
then post what you can't
okay well one is.. Determine whether the ordered pair (2, 15) is a solution of y = 4x - 7.
put the value of x=2 and y=15 if this satisfies the equation then it is a solution else it is not like y=15, x=2 15=4*2-7 15 can't be equal to 8-7 which is 1 so as 15 can't be =1 therefore it is not a solution of this y=4x-7
umm..okay i think i got that :D
next
umm this... :D A plumbing company charges $50 for a service call and $15 per hour. They went on a 3-hour job. How much did the company earn? A. $195
sorry.. A. $195 B. $165 C. $95 D. $65
well, $50 is charge and extra of $15 per hour so for three hours it will be $15*3=$45 and $50 is service call charge so total of $50+$45=$95 okay?
hmm... wait a sec :D
sure , next please
most of the questions are like this, Determine whether the ordered pair (5, 3) is a solution of y = 3x – 4. .... i just wanna know how to solve those :/
look in all these equations just put x=5 and y=3 actually the content of bracket (5,3) are the values of x and y (x,y) now if putting x=5 and y=3 in the equation y=3x-4 satisfies then it is a solution else not now put x=5 and y=3 3=3*5-4=15-4=11 3=15-4 which is not correct if we would have obtained 3=3 then it must be the solution but we got 3=11 which is false so its not a solution
clear?
i dont get it :/ where did the 15 and 11 come from?
i am here.. :D
well at the place of x in the equation put x=5 and at y put y=3 now y=3x-4 put y=3 and x-5 3=3*5-4 ------------ 3*5= 15 3=15-4------------15-4=11 3=11 this is false , clear?
okay it seems confusing but i will go over this a few times later, but thanks :)
just put y= its value and x= the value of x as in ordered pair in the equation and if both the sides are equal you will have it as solution else no
and this will help you more i guess http://www.virtualnerd.com/pre-algebra/algebra-tools/test-ordered-pair-equation-solution.php
next?
please can we stop for now.. i dont wanna do this :(
one more
umm.. are you sure? :D
hahah am i sure come on keep asking
This is Last one.. please 7. Use a table of solutions to find the ordered pair solution for y = 4x – 6 when x = 10. A. (34, 10) B. (10, 34) C. (10, 8) D. (8, 10)
no after this you're gonna do it unless you're finished :)
nope im not even close to being done :P
if we put x=10 in the equation y=4x-6 we will get y= 4*10-6 , just at the place of x put x=10 y=40-6 y=34 therefore your ordered pair is (10,34) which means when x=10 , y=34 clear?
yes clear! :P
hmm next ? unless you are finished
yes i am finished, now thanks! :P lol
actually no.. sorry :)
next
question ? :)
wait please :(
okay :)

whats a quadric eqaution?
or quadratic* sorry
quadratic equations are those whose degree is two like the equation in which maximum power of x is 2 and minimum too like \[x^2+x+2=0, x^2+1=0, x^2=0\] equations in which power of x is two are quadratics ,so this type of equations are not quadratic , \[x+1=0, x^3+3x^2+x+3=0\] in quadratic power of x must be 2
so your answer is option D cuz its cubic x has power 3 clear?
hmmm.. alright :)
next
whats a parabola?
its a conic section, created from the intersection of a right circular conical surface and a plane parallel to a generating straight line of that surface. like consider this |dw:1353988143775:dw| its a parabola and every quadratic equation represents a parabola so all the equations with degree two which means power of x should be 2 represents a prabola
?? clear??
|dw:1353988155323:dw|
is it B?
lol its B
sorry for my bad drawing :P lol thanks !! :D
A- straight line C- cubic curve D- hyperbolic so its B clear?
yes clear thank you! :D
next ?
hmm should i draw the next question or just do screen shot of it, i think drawing would be too slow :P
take snap shot and attach it here fast
alrighty :)
there you go :D

do you know what is vertex? if not then remember every parabola has lowest and highest point that point is called as vertex like the point where curve takes a turn here in this picture its (-2,1) clear??
just see the point in the graph where parabola take,s turn at the bottom
ohh hmm i didnt know that well thanks that helps a lot i think i can do this now :D
great next??
noo i will finish this now :D
next please viki? i know you won't so ask now
what does X-intercepts mean?
hellloo :P
well x intercept means where the curve cuts the x axis or where the line meets x axis here in an example|dw:1353988840083:dw| in this graph we can see that line cuts x axis at 2,0 so x intercept is 2 and y is 3
lol let me explain ;)
intercept simply means the point where curve cuts the axes okay?
huh? :/
what is it not clear?
|dw:1353989048953:dw| you mean these things?
its the point on axes like x axis or y where the curve cuts it okay like take an example of line |dw:1353989013085:dw| so that point 4, 0 says line cuts x axis at 4 so x intercept is 4
yes those things , where line passes the axis
hmm alright i understand now, thanks :D
|dw:1353989111817:dw|
so the answer is (-3,3) ?
no intercept will always have either x=0 or y=0 so it could be (4.0) or (0,3)
but it cant be 4 because line crosses at 3 :/
intercept is the length of or part of either axis where line cuts it so for x intercept you have to put y coordinate=0 and for y you have to put x=0 yes x intercept is 2 because line cuts x axis at 2 and y intercept is 3 cuz line cuts y at 3
clear?
but itc cant be 2!! it has to be one of the answer choices
it*
show me the question please if it asks for x intercept then it would be, 2,0 or if it asks for y then it would be 0,3 show me question please
here you go
1 Attachment
we just did it lol come on are you awake
wait sorry wrong question !! my bad :(
wait :D
quick ;)
there! :D
1 Attachment
look in to th graph it cuts x axis twice at -1 and at -3 so can you find what are the x intercepts?
remember y would be zero
is it A? im not really sure :/
come on if it is cutting x axis at -1 and -3 then x intercepts are -3,0 and -1,0 , silly :) clear?
hmm okay got it! :D thanks :D
next ? :)
wait pelase
sure
lol Please*
hehe
:D
come on now question please
|dw:1353989991234:dw| here is your question ;)
helloooooooooooooooo?
heheheh :D
OMG i was scared of this lol wait a sec
are you going to erase it :(
no wait
where did you go sweetie :(
|dw:1353990129350:dw|
heyyyyy woww :D nice!! ;)
thank you :)
i am all here for my baby bunny , now question please
its place to study not for romance ;)
hehehe :D i know ;) lets carry on :D
post it :D
hehehe your funny :D
wait please :D
come on , hey shall we delete those cuz moderators will ban us lol i have taken photo of it
hmm okay :(
okay leave it as it is :) <3 and baby next question please
im not scared of mods :P and this question is closed anyway :D
okay sweetheart next question please
next question??
i know you are doing something again
|dw:1353990534628:dw| wow sorry that took too long :P
cant you judge , x should have power of 2 so which one it is??
B. ?
correct :)
hmm great thank you :D
next?
hmm i wont draw this time :D
1 Attachment
parabola always have power 2 okay and its drawn up side which means positive so its B , clear?
ohh okay :D thank you! :D
next?
|dw:1353991046364:dw|
what to do in this?? lol
should i post screen shot instead lol ?
what you are supposed to find in this question? vertex?
yes find the vertex :D
and there is no coordinates hahahahaha take snapshot again lol
hmm alright im sorry :( i tried.. :'(
do it now :)
there you go :(
1 Attachment
sorry :(
baby, look it turns at x=1 and y=4 that is the top point of parabola so its (1,4) okay :D ?
okay :D sorry :D this is funny though :D
next ?
lol its really funny hehe
next??
I'm thinking it is A. right?
1 Attachment
oh no, its D, -1,0 and 3,0
oh crap sorry i forgot it is negative :(
look to represent x intercept we write it like (x,0) because y is zero for x intercept and for y intercept we write it like (0,y) cuz x =0 so it cant be A ever cuz that shows y coordinate and you have to find x clear??
yes clear thank you :) this is the last question :)
yes clear thank you :) this is the last question :)
next, i know this is not the last one there are 10
would you like to see proof?
1 Attachment
sure
it is there :D
