Answer:
A: {(7, 12), (1, -5), (3, -10), (2, -5)}
Step-by-step explanation:
A relation should not have any repeating x values (or domains) in the group of coordinates.
B has 1 as all it's domains. B is not a function.
C lists 0 twice as it's domain. C is not a function
D lists 2 twice as it's domain. D is not a function
A is the best answer because it does not repeat any domains in the coordinates. A is a function.
If a quadratic function has zero at x=-9, then point (-9,0) lies on the graph of quadratic function.
A line of symmetry has equation x=-3.5 that is x+3.5=0.
Use formula for the distance from point 
to the line AX+By+C=0:
Thus,
Answer: the distance is 5.5 units.
Answer:
24
Step-by-step explanation:
There are 4 cups in one US quart, 4*6 is 24.
5+5x=Larys
9+4x=Boardwalk
5+5x=9+4x
-4x -4x
5+x=9
-5 -5
x=4
If you rent a bike for four hours the cost will be the same at both places
Answer:
∠G, ∠HGI, ∠IGH
Step-by-step explanation:
» <u>Concepts</u>
To name an angle, you MUST include the vertex either in the middle or have it standing by itself. To clarify, you can either call this angle ∠G, ∠HGI, or ∠IGH because they all include the vertex, G, in the middle or by itself. You put ∠HIG, which is incorrect because the vertex <u>is not </u><u>I</u>.
