Answer:
i think c and e are the answers pls mark me
Step-by-step explanation:
Step-by-step explanation:
You would start by using one of the equations to find y with x in the equation. You want to pick the easier one. I picked this one because it was evenly divisible.
5x+5y=50
5x=-5y+50
x=-y+10
Then you what to plug that in to the second equation and solve for y.
3(-y+10)+4y=32
-3y+30+4y=32
-3y+4y=2
y=2 (because you combined like terms)
Then you would plug back into the first equation and solve for x.
5x+5(2)=50
5x+10=50
5x=40
x=8
x=8, y=2
We have,
f (0) = 7
f (1) = 2f (1-1)-3 = 2×7-3 = 11
f (2) = 2f (2-1)-3 = 2×11-3 = 22 - 3 = 19
Hence 19 is the third no. in the sequence
