You take 150/3. The answer is 50.
-- The trains start moving at the same time.
-- The space between them is initially 252.5 miles.
-- They reduce the distance between them at the rate of (124.7+253.5)=378.2mph.
-- It will take them (252.5 / 378.2) = 0.6676 hour to meet.
That's 40min 3.49sec .
-- After tooting and puffing toward each other for 8 minutes, they still have <em>32min 3.49sec</em> to go before they meet each other. We're all hoping that they're on different tracks.
Answer: y+3 = 4( x + 1)
Step-by-step explanation:
The equation in point slope form is given as :
y -
= m ( x -
) , where m is the slope
slope = 4
point given : (-1,-3)
Using the formula :
y -
= m ( x -
)
and substituting the value , we have
y - (-3) = 4 (x -{-1} )
y+3 = 4( x + 1)
6 - a = 1/3(9a - 18)
6 - a = 3a - 6
-a - 3a = -6 - 6
-4a = -12
a = -12/-4
a = 3..........one solution
