1) -13 = -4a - 2b + c
-13 = -2(2a + b) + c
2) 3 = 4a + 2b +c
3 = 2(2a + b) + c
3) 5 = 16a + 4b + c
5 = 4(4a + b) + c

Answer:
The lowest point is -100 meters, or 100 meters down
Step-by-step explanation:
D(x)=1/36(x-60)^2-100
This equation is in vertex form
y = a(x-h)^2 +k where (h,k) is the vertex
Since a is positive, the parabola opens up
The vertex is the minimum, which means it will be the lowest point
The vertex is (60,-100)
The lowest point is -100 meters, or 100 meters down
The way to write this expression in mathematics is A'∩B
<h3>How to solve for the expression</h3>
In order to get the right way to write this expression we have to break it down in two parts.
First we are told that some of the elements are not in A.
This is represented as A'.
Then we are told that they are in the set B. Hence we have it written as B.
Then the expression not in set A but are in set B would be written as
A'∩B.

Jess rode 4.25 km in 20 min.
Speed = 4.25: 20 = 0.212 km/min
Corey rode 3.75 km in 18 min.
S= 3.75 : 18= 0.208
Mia rode 3.5 km in 17 min.
S = 3.5 :17 = 0.205
Zoey rode 3.6 km in 16 min.
S= 3.6 :16 = 0.225
The greatest rate of speed : ZOE with 0.225 km/min
Answer:
2
