Answer:
64.
Step-by-step explanation:
Sigma notation is ∑48(1/4)^(n-1).
Upper limit = a1 / (1 - r) where a1 = initial population and r = common ratio.
So it is 48 / (1 - 1/4)
= 48 / 3/4
= 48 * 4/3
= 64.
X=-3 Y=8 so (-3,8) is your final answer
4/5 + 8/9. First we have to find a common denominator for

and

.

Now we are going to add:

Make

a mixed number:

So the answer is
