What do you think it is?
c or d
look at the table what do you see
describe what do you see
each number is *3
look clearly at the months and the heights do you see any kind of pattern
oh good eyes
so we are multiplying here by 3
so for the 12 moth what are we gonna get
um not sure
well you just said we are multiplying by 3
for the 12th month
good! so which answer choices have 36 cm
the correct answer is D
ok but what guarantees that?
just because you 36 does not guarantee it is correct
becuase we are trying to find the 12th month and 12*3 = 36 and D is the only one with 36
what if we had two answer choices that have 36 on them
yes in this case you are safe
then i would keep going and keep problem solving
but to confuse you i would have put 36 in more than one and you won't be sure anymore
i'm not sure how to work that.
you have to find that model through the table
ok can you help me with that?
let's take the months as our x (input) and height as our out put ok
y=3x as you said yourself according to table
you give me an x i multiply by 3 to get y the height
so the kind of relation we have here is linear (direct relation)
now what we do is go to options and see which exactly y=3x
in this case we know already it has to be y-9=3(x-3)
ya thats easy to find
if you solve that for y you get y=3x-9+9=3x which is the right one
the answer is still D
i was just teaching how to do more of this problems
thanks so much most people on here just pop in and don't explain much i faned you for sure!
sometimes they will confuse yoiu
thanks gonna close this now:)
no problem :) i'm pleased to help
