Answer:

Step-by-step explanation:
We have the recursive formula of a sequence:

Answer:
15/4 or 3 3/4
Step-by-step explanation:
since 1/5 has 1 as a numerator,
5 x 3/4=
15/4
it will take about 3 hours and 45 minutes
first we multiply 400,000 by 1.20 which equals 480,000 which is the sales revenue for 2008 now we multiply 480,000 by 1.30 which equals 624,000
so your sales revenue for 2009 is $640,000

Subtract the two equation from each other
-3x-7y=-66
-10x-7y=-24
--------------------
7x =-42
x=-6
by substituting in equation 1
(-3)(-6)-7y=-66
18-7y=-66
-7y=-84
y=12
so to check we substitute in the first equation
(-3*-6)-(7*12)=-66
18-84=-66
-66=-66
we check the second equations
-10(-6)-7(12)=-24
60-84=-24
-24=-24
