Who knows how to solve inscribed angles

Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2

How many sides does a regular polygon have if each exterior angle measure is 45 degrees explain your answer, i really don't understand this.
