bekas [8.4K]

Answer:

(-4,4)

Step-by-step explanation:

-5x-10y=-20

10x+10y=0

divide both sides by 2

-5x-10y=-20

5x+5y=0

that makes

-5y=-20

divide both sides by -5

y=4

now substitute 4 for y

10x+10 x 4=0

multiply

10x+40=0

subtract

10x=-40

divide

x=-4

Zepler [3.9K]

Answer:

<h2>x = 3.499 in</h2>

Step-by-step explanation:

       In a kite, the diagonals are perpendicular. Hence \Delta DOC is a right angled triangle.

       DC=7\text{ }in,\text{ }OC=5\text{ }in

From Pythagoras theorem, since \Delta DOC is a right angled triangle, DO^{2}+OC^{2}=DC^{2}.

      Area of \Delta DOC = \frac{1}{2}\times base\times height

=\frac{1}{2}\times DO\times OC=\frac{1}{2}\times OP\times DC\\(2\sqrt{6})\times(5)=(7)\times(OP)\\OP=3.499\text{ }in

From diagram OP=x

∴ x=3.499\text{ }in
