Answer:

(-4,5)

Step-by-step explanation:

-X and X cancel each other out so your're left with

Y=9

2Y=6

Add the like terms together to get 3Y=15

so Y=5.

Then plug in y into one of the equations to get x.

-x+5=9

-x=4

X=-4

So the solution is (-4,5)

In parallelogram ABCD , BE=7x−2 and ED=x2−10 .
Stells [14]

I'm assuming that the diagonals intersect at E. Since diagonals of a parallelogram bisect each other, BE=ED.

  • 7x-2=x²-10
  • x²-7x-8=0
  • (x-8)(x+1)=0
  • x = -1, 8

As distance must be positive, we reject the negative case, so x=8.

Thus, BE=ED=54.
