Answer:
Coordinate of R is (-9, -2)
Step-by-step explanation:
Given
M (-6, 4)
S (-3, 10)
Distance between M and S are x = 3 y = 6
Since M is the midpoint between RS, such that distance between RM = MS
x = -6 - 3 = - 9
y = 4 - 6 = - 2
Answer: The value of x=1.
Measure of CD =1 unit.
Step-by-step explanation:
Given: Segment EC bisects segment AD at C.
That means , EC divided AD into two equal parts AC and CD,
i.e.
Also it is given that
and 
then, we have

So, the value of x=1.
Now, CD = AC = 4(1)-3 =4-3 =1 unit.
Hence, Measure of CD =1 unit.
The answer is ×=w/2e.thats it
