<h3>
Answer: y = -3x+5</h3>
slope = -3
y intercept = 5
==================================================
Explanation:
The given line is in the form y = mx+b, so the slope is m = -3
Any parallel line to this one will also have the same slope, but a different y intercept.
Plug (x,y) = (-1,8) and m = -3 into y = mx+b so we can find new y intercept.
---------------------
y = mx+b
8 = -3(-1) + b
8 = 3+b
8-3 = b
5 = b
b = 5
So because m = -3 and b = 5, this means we have y = -3x+5 as our answer.
Step-by-step explanation:
=a+b+5 this is the answer
in a marathon race (42.195 km), the winner’s time is 2 hours, 13 minutes, and 9 seconds, while the second-place time is 2 hours, 26 minutes, and 6 seconds . The distance is 2.664 km.
D = distance of marathon = 42.195 km = 42195 m
tw = time taken by winner = 2 h 17 min = 2 (60) + 17 = 137 min = 137 (60) = 8220 sec
Vw = speed of winner
speed of winner is given as
Vw = D /tw = 42195/8220
ts = time taken by second place = 2 h 26 min 14 sec = 2 (60)(60) + (26)(60) + 14 = 8774 s
Vs = speed of second place
speed of second place is given as
Vs = D /ts = 42195/8774
distance of the second place holder from the finish line is given as
D' = Vs (ts - tw)
D' = (42195/8774 )(8774 - 8220)
D' = 2664.24 m
D'= 2.664 km
