for what value of k of the pair of equations 3 X + 4 Y + 2 is equals to zero and 9 X + 12 Y + K is equals to zero represents coincident lines ​

hi do you need an answer for your question?

step-by-step explanation:

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
