What is the value of the equation f(x) =2x -3x +7 when x equals 2

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

Given: m∠ adb = m∠cdb ad ≅ dc prove: m∠ bac = m∠bca lol

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.
