Answer:
y = -1/2x + 1
Step-by-step explanation:
The y-intercept can be determined since the line touches the y-axis at the point (0,1), making it 1. The slope can be determined since the line is going down negatively, down one half and right one, making it -1/2
Answer:
2731
Step-by-step explanation:
3 - 1 = 2 = 2^1
11 - 3 = 8 = 2^3
43 - 11 = 32 = 2^5
171 - 43 = 128 = 2^7
683 - 171 = 512 = 2^9
Following the pattern, add 2^11 to 683.
683 + 2^11 = 683 + 2048 = 2731
12k+30-3k=66
12k-3k=36
9k=36
k=4
So find rate
rate=degress in x minutes
rate=140 in 70 minutes
ratiosis 140 to 70
if you wanted to find degrees per minute so you could multiply then do
degreees/1 minute=140/70=14/7=2/1=2 degrees per minute
28 minute times 2 degrees per minute=56 degrees
another way is
140/70=xdegrees/28
solve for x
multipl yboth sies by 28 and simplify
3920/70=x=56
answer is 56 degrees
