The first president is George Washington
729-243=486
486×3=1458
1458+729=2187(x=7)
1458×3=4374
4374+2187=6561(x=8)
4374×3=13122(average rate of change for interval 8 to 9)
13122+6561=19683(x=9)

Answer:
There are 35 blue marbles
Step-by-step explanation:
b = blue marbles
r = red marbles
r+b = 48
b = 2r+9
Substitute b =2r+9 into the first equation
r + (2r+9) = 48
Combine like terms
3r +9 = 48
Subtract 9 from each side
3r+9-9 = 48-9
3r = 39
Divide each side by 3
3r/3 = 39/3
r = 13
There are 13 red marbles
We need to find the blue marbles
b =2r+9
b = 2(13) +9
= 26+9
= 35
There are 35 blue marbles
