Formula for geometric series
an=a1(r)^n-1
a2=1/4(1/3)^1
a2=1/12
Answer:
y=x-9/3
Step-by-step explanation:
f(x)=3x+9
let f(x)=y
y=3x+9
change position of x & y
x=3y+9
rearrange:
x-9=3y
y=x-9/3
Answer:
10 +(20x)
Step-by-step explanation:
Donald has number of twenty-dollar bills = x
He has ten-dollar bill = 1
Total amount of bills = 10 +(20x)
The amount of the bill that Donald have is 10 + (20x)
For answer #3...
just replace (T) with 76.50 in the equation T=9h
Then since this is a division problem you would do 76.50/9=9h/9
This gives you your answer which is h=8.5.
Hope this helps!!:)
