-3x + 2y > 5y + 9
- 5y - 5y
-3x - 3y > 9
-3x + 3x - 3y > 3x + 9
-3y > 3x + 9
-3 -3
y < -x + 3

-3x+ 2y > 5y+ 9
⇒ -3x > 5y -2y+ 9
⇒ -3x > 3y+ 9
⇒ x < (3y+ 9)/(-3)
⇒ x < -y -3

The inequality equivalent to -3x+ 2y > 5y+ 9 is x < -y -3~

Quadrilieral abcd has a dignosed that are congrount and perpendicular to each other what classification can be given to abcd

olga nikolaevna [1]

Answer:

a kite or a square

Step-by-step explanation:

The fact that the diagonals are congruent is irrelevant, unless you also know something about where they cross each other.

A kite has perpendicular diagonals. If they happen to bisect each other, then the result is a rhombus. If the diagonals are congruent, then that rhombus is a square.

Other ways to get there

A pair of congruent diagonals that cross each other symmetrically will define a trapezoid. If they also bisect each other, the result is a rectangle. If the diagonals of that rectangle are perpendicular, then it is a square.
