a) Option B Direct variation, y=1.8x is correct option.
b) Option A Not a direct variation is correct option.
Step-by-step explanation:
a) for the data in the table tell whether y varies directly with X if it does write an equation for the direct variation
The direct variation is represented by:
We need to find k.
Given the values of x and y in table we will find k. if value of k is constant, so x and y varies directly
Since value of k is constant i.e 1.8 so, y varies directly with x.
Option B Direct variation, y=1.8x is correct option.
b) For the data in the table tell whether Y varies directly with x if it does write an equation for the direct variation.
The direct variation is represented by:
We need to find k.
Given the values of x and y in table we will find k. if value of k is constant, so x and y varies directly
Since value of k is not constant so, y doesn't varies directly with x.
Option A Not a direct variation is correct option.

Answer:
The x coordinate is 0.047m while y coordinate is 0.081 m
Step-by-step explanation:
The coordinates of the center of the mass of the system are given as follows
So from the data
m1=0.310, x1=0.20,y1=0.320
m2=0.410,x2=0.110,y2=-0.380
m3=0.210,x3=-0.300,y3=0.630
Now by substitution of the values in the above equation
So the x coordinate is 0.047m while y coordinate is 0.081 m
