The statement explains why the ordered pair is a solution to the system of equations. is the statement true or false?
the ordered pair (−4,−1) is a solution to the system of equations because when (−4,−1) is substituted into the equation, both equations are true.
3x+8y=20
−5x+y=19
true or false?

Every time you drive you will experience a combination of driving conditions and environments.

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29

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.
