Answer:
Step-by-step explanation:
15. (-4-3)/(-5-0)= -7/-5= 7/5
y - 3 = 7/5x - 0
y = 7/5x + 3
16. (-2-3)/(4-0)= -5/4
y - 3 = -5/4x - 0
y = -5/4x + 3
17. (-3+5)/(0+3)= 2/3
y + 5 = 2/3(x + 3)
y + 5 = 2/3x + 2
y = 2/3x - 3
18. (-2-2)/(0+4)= -4/4= -1
y - 2 = -1(x + 4)
y - 2 = -x - 4
y = -x - 2
19. y - 3 = 1/2x - 0
y = 1/2x + 3
20. y - 2 = -(x + 1)
y - 2 = -x - 1
y = -x + 1
21. perp. -5/3
y + 5 = -5/3x + 0
y = -5/3x - 5
22. perp. 1/2
y + 1 = 1/2(x + 4)
y + 1 = 1/2x + 2
y = 1/2x + 1
23. perp. 3/4
y + 5 = 3/4(x + 4)
y + 5 = 3/4x + 3
y = 3/4x - 2
24. perp. 7/5
y - 4 = 7/5(x - 5)
y - 4 = 7/5x - 7
y = 7/5x - 3
Answer: Chris reached Boston at 10:24 a.m.
Explanation:
Since we have given that
Speed at which Chris ran from Newton to Boston = 15 km/h
Speed at which Goffy ran from Newton to Boston = 12 km/h
Time at which both started = 10:00 a.m.
Time at which Goffy reached Boston = 10:30 a.m.
That means Goffy takes half an hour to reach Boston,
so, Distance between Newton and Boston is given by
So, Time taken by Chris to ran from Newton and Boston is given by
So, Chris reached Boston at 10:24 a.m.
