Answer:
d c a
Step-by-step explanation:
Answer:
y = ac / (a - b - c)
Step-by-step explanation:
y(a - b) = c(y + a)
Distribute
ay - by = cy + ac
Subtract cy from both sides
ay - by - cy = ac
Factor out y
y(a - b - c) = ac
Divide both sides by (a - b - c)
y = ac / (a - b - c)
3 to 9 clouds are smiley faces Explaintion- hope it’s right
The nth term is
an=a1(r)^(n-1)
an=1(2)^(n-1)
a1=1
r=2
the sum of a geometric seequence is

a1=1
r=2
we want to find

(since we minus 1, the highest exponet is 9 so add 1 to make it correct)
