The answer is B.)
This is because Since there is one value of y
for every value of x in (-1,-3),(3,-7),(7,-11),(9,-13)
, this <u>relation</u> is a <u>function</u>.

Answer:
Chord: RT (and RS and TU, but those are also diameters)
Diameter: RS or TU
Radii: OU, OS, OT, or OR
Step-by-step explanation:
Chord: A line segment joining two points on a curve. Doesn't have to cross the center. (AKA, they have to touch the outer edge of the circle.)
Diameter: Chord that crosses the center of the circle(All examples given above cross center O)
Radius: Line segment that goes from the center of a circle to an endpoint that lies on the circle.
A={x|x is an even while number between 0 and 2} = ∅ since there is no number between 0 and 2 that is an even whole number. So there is no number to be substituted for x, resulting in an empty set.
Hope that helps!
When you have parallel lines same side interior angles add up to 180 degrees.
Let the first SSI (same side interior) angle be x, and the other SSI be (x - 20).
Therefore, x + (x - 20) = 180
2x - 20 = 180
add 20 to both side
2x = 200
divide both sides by 2
x = 100
x - 20 = 100 - 20 = 80
