What are the coordinates of M' after triangle MNO is reflected over the y-axis, and rotated 90 degrees clockwise with the origin as the center of rotation?
A.(6,0)
B. (0,6)
C.(-6,0)
D. (0,-6)

{I THINK THE ANSWER IS (0,-6)}

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2

With number 11 ( show how you got the answer)
