A quadratic function has a line of symmetry at x = -3.5 and a zero at -9.
What is the distance from the given zero to the line of symmetry?

The graph below could be the graph of which exponential function?

What is always true when two whole numbers are subtracted?

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
