In a math contest, the contestants were given the following piecewise graph. For the final question, they were asked to write the piecewise function of the graph. Circle the name of the competitor with the correct answer.
(Sorry the names aren't in the pictures just find the right function)

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

Use circumcenter theorem to solve for the given values

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
