The diagonals are equal and they bisect each other.
BD=2BX=2(y+4)=2y+8
AC=BD
4y=2y+8
2y=8
y=4

I hope this helps you

AC=BD

BX=XD=AX=XC

AC/2=BX

4y/2=y+4

What type of conic is given by the equation 4x^2+9y^2=36

zvonat [6]

Answer:

This is equation of ellipse

Step-by-step explanation:

we are given

$4x^2+9y^2=36$

We can see that right side is 36

so, we can make right side as 1 by dividing both sides by 36

$\frac{4x^2+9y^2}{36} =\frac{36}{36}$

$\frac{4x^2+9y^2}{36} =1$

$\frac{4x^2}{36}+\frac{9y^2}{36} =1$

we can simplify it

$\frac{x^2}{9}+\frac{y^2}{4} =1$

we can rewrite it as

$\frac{x^2}{3^2}+\frac{y^2}{2^2} =1$

now, we can compare it with standard equation of ellipse

$\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2} =1$

we can see that both equations are similar

so, this is equation of ellipse

Find the slop of (10,5) (18,9)

Arada [10]

Answer:

1/2

Step-by-step explanation:

We can find the slope given two points by

m = (y2-y1)/(x2-x1)

= (9-5)/ (18-10)

= 4/8

= 1/2
