Estimate lim 3x2 - 7x + 1 using a graph.
x=1

Danny draws a transversal, t, on two parallel lines ab and cd, as shown below: he makes the following table to prove that the alternate interior angles are equal: which is the missing justification? (6 points) corresponding angles formed by a transversal on parallel lines are supplementary. corresponding angles formed by a transversal on parallel lines are congruent. co-interior angles formed by a transversal on parallel lines are congruent. co-exterior angles formed by a transversal on parallel lines are congruent.

What could explain what happened when the time was equal to 120 minutes

How do you use the elimination method for this question? explain, because i really want to understand!
