1. If the co-interior angles formed by a transversal and the two line segments are supplementary the two segments are parallel. Determine whether DE is parallel to BC

2. What can you conclude about the heights of (triangle) ADE and (triangle) ABC? How is the height of triangle ADE related to the the height of quadrilateral BCED? Explain.

3. Does this apply for all triangles? Explain your reasoning.

How can you decide witch operations to use to slice a two step equation

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x
