average rate of change = change in y / change in x
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
you're going from x=3 to x=5 so, chang ein x = 53 = 2

do u knw how to find change in y, from the given table ?
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
But what about the 1 ?
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
And no , all of this is confusing to me :(
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
its okay to get confuse when u start... did u get how we got the change in x ?
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
Yes, we subtracted them? :o
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
yes, now look at table. and tell me wats the y value, when x = 5 and when x = 3
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
When x=5 , the y value is 2 . When x=3 , the y value is 4
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
excellent ! so change in y = 24 = 6
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
average rate of change = change in y / change in x = 6/2 = 3
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
see if that makes sense
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
That does makes sense ! :D

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
(1, 3) and (1 , 7)
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
those are the given points
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
rate of change , m = change in y / change in x = y2y1 / x2x1
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
= 73 / 11 = 4/2 =2 so, m = 2
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
Right :) I'm working it out on paper with you :P
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
now, use this : equation of line in slope, point form is, y  y1 = m(xx1) plugin values :)
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
That would be y  3 = 2 (x  (1)) ?
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
So is that it ? :o
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
not yet, thats one equation. we could have used the second point aswell... let me do it for you :)
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
Oh , okay :) Thank you !
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
slope m = 2, second point (1 , 7) so m = 2, x1 = 1, y1=7 yy1 = m(xx1) plugin values now
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
y7 = 2(x1)
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
thats the second equation. now see which one exists in the given options , and tick that one...
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
It's option 2 ! :)
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
You helped me understand this ! Thank you :D
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
Yes ! takes time to master these... i see you're already getting good at these :)

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
Okay here's the last question :) Jack and Jill had 3 pails of water. Each trip up the hill, Jack and Jill obtained 1 more bucket of water. Which of the graphs below represents Jack and Jill's number of pails over time?
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
check ur 3rd & 4th graphs. they are same !
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
That's how it is on my quiz :( It's probably an error ... Is there anyway to do this and figure out the answer and see if it's on one of the graphs ? If not , I don't think my teacher will deduct points for the question being incorrect lol
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
ohk, but wat wud u pick whe u have two exact same graphs ?
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
Ugh I'm just going to chose an answer and tell my teacher there was an error with the questions . Thank you though :)
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
good :) here is how we solve it : since to start with, they have 3 pails of water, that means, the line must cit the y axis at 3
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
since the line is cutting yaxis at 3 only in 3rd & 4th graphs, one of them must be ur answer
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
and since, both graphs are exact same, u toss a coin and pick one
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
Haha okay :) Thank you so much for your help :)
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
but first one is not 3
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
It's not ? :( What's the first one ?
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
2x+4 = 3x11 subtract 2x both sides 4 = x  11 add 11 both sides 15 = x
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
first one is 15

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
Ohhhhh ! I know what I did wrong ! I added 3x and 2x by mistake ! haha
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
:) i thought so... third equation : \(\large \frac{2x+1}{3} = \frac{x+6}{2}\)
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
cross multiply
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
How would I start ? :( I'm no good in cross multiplying ..
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
\(\large \frac{2x+1}{3} = \frac{x+6}{2}\) \(\large 2(2x+1) = 3(x+6)\)
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
Omg that makes sense . ! Okay I understand now !
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
cool :) solve x
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
\(\large \frac{2x+1}{3} = \frac{x+6}{2}\) \(\large 2(2x+1) = 3(x+6)\) \(\large 4x+2 = 3x+18\) solve x
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
4x + 2 = 3x + 18 ? Then solve ?
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
Okay one moment !

Is x = 16 ?
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
\(\large \frac{2x+1}{3} = \frac{x+6}{2}\) \(\large 2(2x+1) = 3(x+6)\) \(\large 4x+2 = 3x+18\) subtract 3x both sides \(\large x+2 = 18\)
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
that gives, x = ?
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
Oh sorry I subtracted 4x by mistake !
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
ok.. x = ?
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
\(\large \frac{2x+1}{3} = \frac{x+6}{2}\) \(\large 2(2x+1) = 3(x+6)\) \(\large 4x+2 = 3x+18\) subtract 3x both sides \(\large x+2 = 18\) subtract 2 both sides \(\large x = 16\)
 10 months ago

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
Should be 16 !
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
x = 16 ! :)

LaynaMae Group TitleBest ResponseYou've already chosen the best response.1
So equations 1 and 3 have the same solution !
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
yes ! so we got, first one, x = 15 second one, x = 16 third one, x = 16
 10 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
careful madam, equations 2 and 3 have the same solution
