distance from the point to O, so it can never be negative so answer is
b.oppsite
Hello!
The equation for point-slope form is
y - b = m(x - a)
m is the slope
(a, b) is a point the line passes through
We are looking for a equation that follows this
The answer is C because a point the line goes through is (6, 2)
The answer is C
Hope this helps!
Answer:
20 seconds
Step-by-step explanation:
speed = distance/time
distance = speed * time
The faster racer will catch up to the slower racer in x meters ahead of the slower racer.
The faster racer is 40 meters behind the slower racer, so he travels x + 40 until he catches up.
Slower racer:
speed = 12 m/s
distance = x
time = t
Faster racer:
speed = 14 m/s
distance = x + 40
time = t (the same time as the slower racer)
Slower racer:
distance = speed * time
x = 12t
Faster racer:
x + 40 = 14t
System of equations:
x = 12t
x + 40 = 14t
Since the fist equation is already solved for x, substitute 12t for x in the second equation and solve for t.
12t + 40 = 14t
40 = 2t
20 = t
t = 20
The faster racer catches up in 20 seconds.
Either, The first one or the third one.
