has a slope of _______ ?

By using natural log.

ln1.167=100000ulne   (lne=1)

ln1.167/100000=u

u=0.00000154436.... approx

simultaneous equations...

I would start this off by making x or y the subject.

So 1st Equation now equals x=13-2y

Now i sub equation 1 into equation 2

So -2(13-2y)-3y=-18

-26-4y-3y=-18

7y=-8

y=-8/7

Then sub the y value into equation 1 to get x value

x+2(-8/7)=13

x-16/7=13

x=107/7

Rules of indicies: A^N X A^M = A^N+M

Therefore x ^2/7 times x ^ 3/14 = x^1/2

The forumula for this is Total amount at the start(1+Percentage/100)^number of years

4500(1+13/100)^13 = 22041.04996

Therefore at the end of 13 years a person will have 22041.05 dolla
