At what point do the lines represented by the equations y=3x+1 and y=−2x−8 intersect?

4+6x-3x^3 in standard form with explanations because i don’t understand

What is an alternate exterior angle

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
