B and C I believe .............
Rule: The diagonals of any parallelogram bisect each other. In other words, they cut each other in half.
This means DF is cut into two equal pieces: DH and HF.
Similarly, GE is cut into two equal pieces: GH and HE.
DH = HF
x+5 = 2y
x = 2y-5
GH = HE
4x-3 = 4y+1
4(x)-3 = 4y+1
4(2y-5)-3 = 4y+1 ... x has been replaced with 2y-5
8y-20-3 = 4y+1
8y-23 = 4y+1
8y-4y = 1+23
4y = 24
y = 6
If y = 6, then x is
x = 2y-5
x = 2(6)-5
x = 12-5
x = 7

Answers:
x = 7 and y = 6
Answer:
The scatter plot is attached.
Step-by-step explanation:
In a scatter plot, we graph the independent variable on the x-axis and the dependent variable on the y-axis.
In this case, age is independent and weight is dependent.
This means the points we plot are:
(7, 50); (7, 60); (8, 65); (8, 70); (9, 70); (9, 80); (10, 75); and (10, 90).
The answer is most definitely D :)
