Answer:
y = -6
Step-by-step explanation:
-6 + 8 = 2
6x+3y=0
3x+3y=9
6x+3y=0
3y=9-3x
6x+9-3x=0
X=-3
3y=9-3x(-3)
Y=6
(X,y)=-3,6
Answer:
The value of XY is 20.
Step-by-step explanation:
Given:
XZ = 16
YZ = 12
Since the triangle is not shown:
Assuming it is a right angled triangle with right angle at ∠Z.
We have drawn the triangle for your reference.
Now by Using Pythagoras theorem we get;
![XZ^2+YZ^2=XY^2](https://tex.z-dn.net/?f=XZ%5E2%2BYZ%5E2%3DXY%5E2)
Substituting the values we get;
![XY^2 = 16^2+12^2 = 256+144 =400](https://tex.z-dn.net/?f=XY%5E2%20%3D%2016%5E2%2B12%5E2%20%3D%20256%2B144%20%3D400)
Now taking square root on both side we get;
![\sqrt{XY}=\sqrt{400}\\\\XY =20](https://tex.z-dn.net/?f=%5Csqrt%7BXY%7D%3D%5Csqrt%7B400%7D%5C%5C%5C%5CXY%20%3D20)
Hence The value of XY is 20.
Answer:
Step-by-step explanation:
the slope would be y2-y1/x2-x1
so the distance is y and the time is x so what you are going to do is 30-18 over 5-3 which then means it would be 12/2 which equals 6
Answer:
The first one
