For every minute you exercise you burn 8.5 calories. It's a linear pattern, so the graph would be a line.
The more minutes you exercise, the more calories you burn, so the graph would rise from left to right.

The larger the number of minutes, the more calories you would burn.
The answer is D.

Answer:
The first term is:
Step-by-step explanation:
The arithmetic sequence is defined by

where
is the first term
is the common difference
as
the 17th term of an arithmetic sequence is 51.
i.e. 
so

∵
,
, 
∵ 

Therefore, the first term is:
D. 1/4 + 1/5 = 5/20 + 4/20 = 9/20 = 45/100 = 0.45
The answer is 75 degrees I believe.
45 + 60 + x = 180
I’m pretty sure I’m correct but I’m so sorry if I’m wrong.
