Suppose one puppy weighs 5 pounds at birth and grows at a rate of 0.25 pounds per month over the first several months. Another puppy weighs 4 pounds at birth and grows at a rate of 0.4 pound per month. After how many months will the puppies weigh the same amount? And how to graph it.

Question

anonymous · Answer

i have the answer i just need to know how to graph it

loser66 · Answer

If you said so, I assume that you know the equations of both them, right?
show them please.

anonymous · Answer

ok

anonymous · Answer

well i just need to know how to graph it

anonymous · Answer

because the answer is 4

loser66 · Answer

nope, to graph something, you need the equation of that thing.

anonymous · Answer

the puppy when it was born grew 5 pounds and grew 0.25 a month and the other puppy when it was born was 4 pounds and grew 0.5 a month

anonymous · Answer

x+Y=4

loser66 · Answer

oh, NNNNNNNNNNNNNNNNNO

anonymous · Answer

i really don't know how to do this

Let's call the p1 is the puppy 1, at born, its weight is 5 lb
                                               after 1 month, it is 5 +0.25
                                               after 2 month, it is 5+ 0.25*2, right?
                                              after 3 months, it is 5+0.25*3

loser66 · Answer

hence the equation of the puppy 1 is y = 5 + 0.25 *x

anonymous · Answer

Oh ok I get it

loser66 · Answer

do the same with puppy 2, show your brain
