Answer:
B) y=2x+3
Step-by-step explanation:
Answer:
an = (n+3)/(n+1)
Step-by-step explanation:
The sequence can be written as ...
4/2, 5/3, 6/4, 7/5, 8/6, ...
where the first numerator is n+3 and the first denominator is n+1. Each numerator and denominator increase by 1 from term to term, so the explicit formula can be written
an = (n+3)/(n+1)
3:5.....added = 8
3/8(40) = 120/8 = 15 m <== one piece
5/8(40) = 200/8 = 25 m <== the other piece
= 2 1/35
75/7 divided by 5/1
71x1/ 7x5
= 71/ 35
Therefore, 2 1/35
