Answer:
A
Step-by-step explanation:
The explicit formula for a geometric sequence is
f(n) = f(1) 
where f(1) is the first term and r the common ratio
Here f(1) = 64 and r =
=
=
, then
f(n) = 64
→ A
Answer:
-5/6
Step-by-step explanation:
Use slope intercept form: 
=
= -5/6
7s + 20 = 4s -13
7s - 4s = -13 -20
3s = -33
s = -33/3
s = -11
It would be 2.9 because if the number to the right of the number your rounding is 5 or higher you round up to the next number. If the number is 4 or lower you round down to a 0.
Answer:
No Solution.
Step-by-step explanation:
x+y=8
y=3-x
-------------
x+(3-x)=8
x+3-x=8
x-x+3=8
0+3=8
3=8
