A cold front is moving in and the meteorologist says that the temperature will decrease at a rate of 5 degrees per hour throughout the night. Which equation models the change in the temperature over the course of 6 hours? A. (5)(-6) = -30 degrees
B. (5)(6) = 30 degrees
C. (-5)(-6) = -30 degrees
D. (-5)(6) = -30 degrees

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
