Answer:
a) Function? No
b) Domain: 
c) Range: 
Step-by-step explanation:
a) Function? No
We want to determine whether the graph of the relation is a function or not.
When we draw a straight line at x=-1, it will intersect the graph at several points, therefore the graph fails the vertical line test and hence it is not a function.
b) The domain refers to all x-values for which the function is defined.
From the graph the domain is
because the ends of the graph are closed.
c) The range is the set of all y-values for which the graph is defined.
From the graph the range is 
Answer:
-1.2
Step-by-step explanation:
The two lines have different slopes and intersect at one point in the plane. A consistent system is considered to be a dependent system if the equations have the same slope and the same y-intercepts. In other words, the lines coincide so the equations represent the same line.
Answer:
-200, 3, 10, -8, 2, -7
Step-by-step explanation:
1. A drop of 200 feet
Integer Value =-200
A point of zero means there is no decrease/increase in the height. No drop from present point.
2. An expansion of 3 cubic meters
Integer Value =3
A point of zero means there is no expansion.
3. Earn 10 points
Integer Value=10
A point of zero means there is no increase in points. No point is earned or added.
4. Reduce by 8 inches
Integer Value=-8
A point of zero means there is no change in the length of height of the given object.
5. Gain 2 pounds
Integer Value=2
A point of zero implies no pound or weight was gained.
6. A drop of 7 degrees
Integer Value=-7
A point of zero implies that there is no change in degrees.
Obtuse scalene, no equal sides, so no equal angles, and the one angle is over 90°
