Given:
The graphed point is (60,-20).
To find:
The ordered pair that would form a proportional relationship with the given point.
Solution:
If y is proportional to x, then
Where, k is the constant of proportionality.
For the given point,
For option (A),
For option (B),
For option (C),
.
The point (-30,10) gives the same value of the constant of proportionality. So, the point (-30,10) forms a proportional relationship with the given point.
Therefore, the correct option is C.

Answer:
-16
Step-by-step explanation:
The absolute value function gives the positive value of the argument, so this is ...
-4|-4| = -4·4 = -16
Answer:
55°
Step-by-step explanation:
In triangle BAC, angle C =
180° - 90° - 70°
Angle C = 20°
In triangle DAB, angle C =
180° - 90° - 55°
Angle C = 35°
Add both angles
20° + 35° = 55°

Answer:
In mathematical analysis, the word region usually refers to a subset of or that is open (in the standard Euclidean topology), connected and non-empty. A closed region is sometimes defined to be the closure of a region. Regions and closed regions are often used as domains of functions or differential equations.
