Question 987663: So I have a linear equation f(t)= 100(0.2)^t/4
Using this I am supposed to show that the halving time is constant no matter what t we consider, if you add +t=1.725 to any value for t, the value is halved.
I know how to express this in words, as it's fairly intuitive, but I'm not sure how to demonstrate it in mathematical notation for any value of t.
It would be very helpful if you could also show the halving time values over the range of f(0) to f(10)
Thanks.

This is what I"ve tried but don't know if I'm right. Plus I need to know how to check my work.
3x+4=12x+5 I saw somewhere that I make the 4 a - why do I make it a negative?
then add 4 to both sides
3x=12x+9 then divide all by 3
x=4x+3
Where do I go from here and please show me how to check my work. Thank you and God bless.
