Answer:
52
Step-by-step explanation:
a(n)=-5+(n-1)3
a(20)=-5+(20-1)3
a(20)=52
R=7/5
You can list two equations:
2s+10r=42 and 4s-10r=42.
Then try to delete S, you will get r
First rewrite as y = ..., just move the +3 to the other side (sign flips):
y = -3.
Then replace y by f(x):
f(x) = -3.
This is a straight line at y=-3.
Answer B.
