Answer:
I think you have it right with C
Step-by-step explanation:
A1 = first term = 8
<u>Plug in a1 = 8:</u>
an = 8 + (n - 1)d
<u>FInd d:</u>
Given that a2 = 5
5 = 8 + (2-1)d
5 = 8 + d
d = -3
<u>Plug in d = -3:</u>
an = 8 -3(n - 1)
Answer: an = 8 -3(n - 1) ; <span>n ≥ 1</span>

Answer:
x=3
y=11
Step-by-step explanation:
5x + 2y = 37
y = x + 8
5x+2(x+8)=37
5x+2x+16=37
7x=21
x=3
y = (3) + 8
y=11
