I'm pretty sure it's d. y=-3x
Answer: D
Reason: Both of the data shown is in no way symmetric
The answers is 2.8 and or 2.83 which ever your answer chose is
Original locations:
Annie: (5, -11)
Barbara: (-7, 13)
Note that the midpoint between two points (x₁, y₁) and (x₂, y₂) is
[(x₁+x₂)/2, (y₁+y₂)/2]
Therefore the meeting place has coordinates
[(5-7)/2, (-11+13)/2] = (-1, 1)
Barbara ends up at (-5, 5).
The positive difference in the y-coordinates between (-1, 1) and (-5, 5) is
5 - 1 = 4
Answer: 4
120
Step by step explanation:
Divide 1200 by 10
That equals 120
You can back check by multiplying 120 by 10
