Create a system of two linear equations that has solution x = 4 and y = -5 and one of the equations is y = -2x + 3. Explain all steps. please dont wanna fail

Consider 6x2 + 6x + 1. which term immediately tells you that this expression is not a perfect square trinomial? justify your answer

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.
