Car A Car B
d=rt d = rt
d = ra * 2.4 d = rb 4
ra = rb+22
distances are the same so set the equations equal
ra * 2.4 =rb *4
substitue in for ra
(rb+22) 2.4 =rb *4
distribute
2.4 rb +52.8 = 4 rb
subtract 2.4 rb from each side
52.8 = 1.6 rb
33 = rb
Car b travels at 33 miles per hour
Car a = 33+22
Car a = 55 miles per hour
Step-by-step explanation:
Since the first coordinates are both (0,0) it implies that the line passes through the origin.
The slope of the line is therefore 5/8
The equation:
y-0=5/8(x-0)
y=5/8x
Answer:
s-64 and k-116
Step-by-step explanation:
Answer:
y=(-4/3)x-1
Step-by-step explanation:
Slope or m=-4/3
Y-intercept or b=-1
Putting in the standard equation y=mx+b
y=(-4/3)x+(-1)
y=(-4/3)x-1
