We have seen in the Triangle Sum Conjecture that thesum of the angles in any triangle is 180 degrees. TheQuadrilateral Sum Conjecture tells us the sum of theangles in any convex quadrilateral is 360 degrees. Remember that a polygon is convex if each of itsinterior angles is less that 180 degree.

The sum of the interior angles of a quadrilateral will always be 360°

The coordinate plane below represents a city. Points A through F are schools in the city.

Part A:
a system of inequalities that only contain points D and E in the overlapping shaded regions is
5y + 2x > 12
2y - x < 12

Part B:
To verify that points D and E are solutions to the system of inequalities, we plug in the coordinate points of points D and E into the system of ineaqualities.

Part C:
To identify the schools that Timothy is allowed to attend we plug in the coordinate values of the points to see which satisfies the inequality y < 3x - 3. Thus Timothy is allowed to attend schools C and F.

Answer:

y = - 4x + 20 ... slope=-4 y intercept:20

Step-by-step explanation:

2y+8x=20

2y=-8x+20

y = - 4x + 20 ... slope=-4 y intercept:20

(y = mx + b)
