Firstly make t the subject for both equations
(x-7)/6=4^t
(y+2)/3=4^(-t)
Times them together to eliminate t
((x-7)/6)((y+2)/3) = (4^t)*(4^-t)=4^0=1
Rearrange to the form required<...

We will mainly be using a whiteboard but here are some notes:Is (x-3) is a factor of f(x), then if x=3, f(x) =0. I.e. x=3 is a solution too. If we know x =3 is a solution we can solve the other 2 roots by...

the action potential arrives at the terminal of the axon. The arrival of the action potential will cause voltage gated calcium ions to open allowing the calcium ions to rush into the axon terminal. The ar...

 1.    DNA is double stranded. This means that when the strands separate during replication, both strands can be used as templates to produce two new double stranded DNA ,each containing one of the origin...

I will begin by considering what apriori knowledge and then intuition and deduction are. On the basis of this I will explain how Descartes argues we can gain a priori knowledge through intuition and deduc...
