0.25q + 0.1d = 4.95
d = 3q

0.25q + 0.1(3q) = 4.95
    0.25q + 0.3q = 4.95
               <u>0.55q</u> = <u>4.95</u>
                0.55     0.55
                      q = 9
0.25(9) + 0.1d = 4.95
    2.25 + 0.1d = 4.95
  <u>- 2.25             - 2.25</u>
               <u>0.1d</u> = <u>2.7</u>
                0.1     0.1
                    d = 27

Answer:

the coordinates of the center of rotation is (4 , 3)

Step-by-step explanation:

*The line which passes through points (4 , 1) and (4 , 5) is vertical because the points have same x coordinates and its length is 5 - 1 = 4

*The line which passes through points (2 , 3) and (6 , 3) is horizontal because the points have same y coordinates and its length is 6 - 2 = 4

*These two lines intersect each other at their mid-point and this mid-point is the center of rotation

*The mid point is (\frac{4+4}{2},\frac{5+1}{2} )= (4,3)

 or (\frac{2+6}{2},\frac{3+3}{2}=(4,3)
