Suppose that a certain strain of pea plant requires 14 days to reach a height of 6 inches and 30 days to reach a height of 16 inches. How many days would it take a plant of this strain to reach a height of 12 inches? * i got 15 days, am i right? *

Let's just check with the steps, Did you get m ?
anonymous
  • anonymous
m?
anonymous
  • anonymous
the slope :)

ohh, noo i just cross multiplied and divided (:
anonymous
  • anonymous
It's okay, you must find the slope to find the equation of the line :) m = y2-y2/x2-x1 after that, choose any of the given points to plug in the following equation : y - yo= m(x-xo) :)
anonymous
  • anonymous
oh wait a min, wasn't the question find the linear equation?.-.
anonymous
  • anonymous
noo (:
anonymous
  • anonymous
oh dear, but you wrote that in the previous one >_< lol
anonymous
  • anonymous
the other one was, but not this one lol
anonymous
  • anonymous
oh okay, then you have to use the equation you got in the previous question then plug in x to find y :) since we said that y = height x = number of days when you plug in x, you'll get y, that's it ^_^
anonymous
  • anonymous
wait what
anonymous
  • anonymous
so you have an equation in the form of : y = mx + B <-- from the previous question plug in y = 12, to get x = number of days ^_^
anonymous
  • anonymous
what what? ._.
anonymous
  • anonymous
ohh dont worry, I guess that the question forgot to put "assume a linear eqn "
anonymous
  • anonymous
lol , anyhow, did you understand what you have to do now bailey ? ^_^
anonymous
  • anonymous
because otherwise you would assume expxonential growth , but im assuming the asker hasnt done that yet :P
anonymous
  • anonymous
>_> :P
anonymous
  • anonymous
do you know what to do now bailey? :)
anonymous
  • anonymous
kind of (:
anonymous
  • anonymous
:) not convincing me here lol Alright, did you find the equation from the previous question? :)
anonymous
  • anonymous
from this question i got y=x+12
anonymous
  • anonymous
:)
anonymous
  • anonymous
alright, now we said that x = represents the number of days right? and y =height, right?
anonymous
  • anonymous
yepp!
anonymous
  • anonymous
alright then, the question wants to know how many days would it take a plant to reach 12 inches right? so in this case y = 12, all you'vegot to do is plug it in the equation and find x^_^
anonymous
  • anonymous
got it? :)
anonymous
  • anonymous
so to find x, what would i have to do, combine like trems? or no.
anonymous
  • anonymous
nope you have : y = x + 12 where x = days and y = height = 12 12 = x + 12 x = 0....hmm there's something wrong, are you sure of your equation?
anonymous
  • anonymous
no :/
anonymous
  • anonymous
(14,6) ( 30,16) m = (16-6) / (30-14) = (5/8)
anonymous
  • anonymous
m = y2-y1/x2-x1 m = (16-6)/(30 - 14) m = 0.625
anonymous
  • anonymous
taake the first point
anonymous
  • anonymous
y-6 = (5/8) ( x-14)
anonymous
  • anonymous
so it's y=5/8x+12??????????
anonymous
  • anonymous
y= (5/8)x -(11/4)
anonymous
  • anonymous
now plug this in the following : y - yo= m(x-xo) <-- choose any point: y - 12 = 0.625(x-30) y = 0.625x - 6.75
anonymous
  • anonymous
we are both wrong I think
anonymous
  • anonymous
that is your equation, now plug in the 12 inches to find the number of days : 12 = 0.625x - 6.75 0.625x = 18.75 x = 30 So it takes 30 days? .-. LOL there's something wrong >_
anonymous
  • anonymous
IKR i couldnt find the answer either
anonymous
  • anonymous
what are we missing o_o?
anonymous
  • anonymous
wait I am right :P
anonymous
  • anonymous
IDK (: lol
anonymous
  • anonymous
y= (5/8)x -(11/4)
anonymous
  • anonymous
are you sure x = represents the number of days?, oh so my answer is true? LOL
anonymous
  • anonymous
^ thats right
anonymous
  • anonymous
same thing, but mine is in decimal lol, but wait 11/4?
anonymous
  • anonymous
12 = (5/8)x -11/4 (5/8)x = 14.75 x= (8/5) * 14.75 = 23.6 days
anonymous
  • anonymous
which makes sense, its half way between 14 and 30
anonymous
  • anonymous
about
anonymous
  • anonymous
oh right >_< I've put 12 insteadof 16, sorry sorry , thank you elec ^_^"
anonymous
  • anonymous
I always miss something o_o, my apologies ^_^
anonymous
  • anonymous
thanks darlings, your AMAZING (:
