3x+7y=28 in y intercept form and find the slope

The ph level of a blueberry is 3.1 what is the hydrogen-ion concentration [h+] for the blueberry

Rewrite the following quadratic functions in intercept or factored form. show your work. y = x^2 + 7x + 10

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.
