The set is empty since there are no common elements
<h3>Set theory</h3>
Given the following sets
A={0,2,4,6,8} and B={-2,-4}
Required sets
A n B
Since intersection means that we are to write out all the values common to the set A and B, hence the equivalent set will be;
A n B = {}
The set is empty since there are no common elements

Answer:
X^3x4
Step-by-step explanation:
Anything that has an x to the power of somthing greater than 1 is a quadratic function.
Answer:
Denote O as center of circle, draw OA, OC.
As property of tangent line from outside of circle (angle OAD = angle OCD = 90 deg):
=> AOC + D = 180
Moreover, angle AOC = 2 x angle B = 2 x 65 = 130
=> D = 180 - 130 = 50 deg
Hope this helps!

X + 2y = 1 ______×1
4x + y = 11 _____ ×2
x + 2y = 1
8x + 2y = 22
8x + 2y = 22
(-)
x + 2y = 1
_____________
7x = 21
x = 3
3 + 2y = 1
2y = 2
y = 1
