By definition we have to:
d = v * t
where,
d: distance
v: speed
t: time
We have then that the speed is:
(360-210) = v * 2.5
Clearing we have:
v = (360-210) /2.5
v = 60 mph
We now write the generic equation of distance:
d (x) = 60x
Where,
x: time
Answer:
an equation that represents (x), the distance Ainsley is from Orlando after x hours is:
d (x) = 60x
Answer:
42
Step-by-step explanation:
Based on the information given, point j is the midpoint, as it is shared by both line segments. Set the equation:
pb = pj + jb
Note:
pj = 14
jb = 28
Plug in the corresponding numbers to the corresponding variables:
pb = pj + jb
pb = 14 + 28
pb = 42
pb = 42 is your answer.

A zero of a function is the value of x for which f(x) = 0
f(x) = 16x^2 + 32x - 9 = 0
16x^2 - 4x + 36x - 9 = 0
(16x^2 - 4x) + (36x - 9) = 0
4x(4x - 1) + 9(4x - 1) = 0
(4x + 9)(4x - 1) = 0
4x + 9 = 0 and 4x - 1 = 0
4x = -9 and 4x = 1
x = -9/4 and x = 1/4
