The coordinates of D are (-3, -7)
First we need to find the coordinates of B. In order to do that we simply take the average of the two points that make up the segment for which it is the midpoint (A and C).
Average of x's
-9 + -1 = -10/2 = -5
Average of y's
-4 + 6 = 2/2 = 1
Therefore, the coordinates of B are (-5, 1).
Now we can find D by noting the E will be the average of B and D. So we can use the average equation to determine the values of D.
Average of x's
(B + D)/2 = E
(-5 + D)/2 = -4
-5 + D = -8
D = -3
Average of y's
(B + D)/2 = E
(1 + D)/2 = -3
1 + D = -6
D = -7
Now we know the coordinates of D to be (-3, -7)

Answer:
Step-by-step explanation:
1,2,3,(4),5,6,7
median (middle number) or Q2 = 4
Q1 (lower quartile) = 2
Q3 (upper quartile) = 6
IQR = Q3 - Q1 = 6 - 2 = 4
Answer: Acute Angle
Step-by-step explanation:
Any angle 89 degrees or less will identify as an acute angle.
Answer:
The relationship is proportional for the turtle and the equation is Distance = 54*Time
Step-by-step explanation:
Turtle’s run:
Distance (meters) | Time (minutes)
108 | 2
405 | 7.5
540 | 10
1768.5 | 32.75
Rabbitt’s run:
Distance (meters) | Time (minutes)
800 | 1
900 | 5
1107.5 | 20
1524 | 32.5
The relationship between distance traveled and time is proportional if this equation is satisfied:
Distance = k*Time or k = Distance/Time
where k is a constant
For the turtle:
108/2 = 405/7.5 = 540/10 = 1768.5/32.75 = 54
Then, the relationship is proportional and the equation is Distance = 54*Time
For the rabbit:
800/ 1 = 800
900/5 = 180
1107.5/20 = 55.375
1524/32.5 = 46.89
Then, the relationship is not proportional.
