Aquadilateral has diagonals represented by y=2x+5 and x+2y= -8. what is true about the quadrilateral? explain.

( do not give out a flat out answer without explaining, spam, or lie. i really want to understand this topic. you! )

The quadrilateral has diagonals which are perpendicular to each other.

Step-by-step explanation:

The equations of the diagonals are given, as

 and  .

The second equation can be written as,

The slope of the first line is m1 = 2 and slope of second line is m2 = .

Multiplying the two slopes, we get,

= (m1)(m2) =

In coordinate geometry, when slopes of two lines are perpendicular, their slopes product is -1.

Thus, above two lines are perpendicular.

Thus the quadrilateral can be Rhombus,Square or Kite.

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
