Answer:
x+y=10 which means that x=10-y
Replace 10-y in the other equation which gives you:
10-y-y=6
10-2y=6
-2y=-4
y=2
Replace 2 in any of the 2 equations same answer for both:
x+y=10
x+2=10
x=8
So,


=512-8
=504
Hope this helps!

Answer:

Step-by-step explanation:
we are given a quadratic equation
we know that quadratic equation is same as equation of parabola
so, we can use formula

Focus is

now, we can compare it with given focus
=(8,-8)
we get


Directrix is

we are given directrix =-6

we got two equations as


now, we can add both equations
and we get




now, we can find 'a'


now, we can plug back all values
and we get
So, equation of parabola is

Hello,
1)
3x²y²-2xy²-8y²=y²(3x²-2x-8)
=y²(3x²-6x+4x-8)
=y²(3x(x-2)+4(x-2))
=y²(x-2)(3x+4)
2)
x²-36=x²-6²=(x+6)(x-6)
