A. I Believe because Data is collected by sample?
Answer:
Step-by-step explanation:
We have the equation of the position of the object
We need to solve the equation for the variable a
Subtract 
and 
on both sides of the equality
multiply by 2 on both sides of equality
Divide between 
on both sides of the equation
Finally
The preimage WXYZ is to undergo a rotation of 90° in the clockwise direction.
A 90° clockwise rotation leads to the following change in the coordinates;
(x,y) -> after rotation (y,-x)
this rule applies for all the vertices in the preimage
W - (3,-5) --> W' (-5,-3)
X - (1,-3) ---> X' (-3,-1)
Y - (-1,-5)---> Y' (-5,1)
Z - (1,-7) ---> Z' (-7,-1)
therefore the new coordinates are W' (-5,-3), X' (-3,-1), Y' (-5,1) and Z' (-7,-1)
I think the answer is 6 and 5 because 6+5=11 and 6-5=1
<span>. Both can be solved by graphing. Both can have two solutions.</span>
