Answer:
static
Step-by-step explanation:
Static methods or variables are called on the class name and not on the object (although some programming languages like C# allow static methods to be called on objects). In fact, you do not need to have created any object before you call a static method. It is quite possible to have all the methods in a class as static, in which case the class is effectively static. Such classes are usually utility classes. Most times, they are not instantiable.
Instance methods are called using the name of an object.
speed = distance / time
... = (158 mi)/(2 h) = 79 mi/h
Jon must maintain an average speed of 79 mph to get there in the time allotted.

Answer:
(-6,-2)
Step-by-step explanation:
Hello! Lets get started!
By looking at this problem, we see that both equations equal 2. This makes this problem much easier!
While there are a few methods you could solve this, I will use substitution. First, I need to find what x is in terms of y!
There are many different ways you could do this, here are two:
-x = 2-2y ==> x = -2+2y
-x + 2y = -3x + 8y ==> 2x = 6y ==> x = 3y
For this problem, I am going to use the second answer, x = 3y, as it is simpler!
We need to substitute 3y in for x in either equation; I am going to use the first equation, -x + 2y = 2.
-3y + 2y = 2
-y = 2
y = -2
Now, lets solve for x!
-x + 2(-2) = 2
-x - 4 = 2
-x = 6
x = -6
After plugging the answers into both equations, we see that they are in fact true!
Therefor, our final answer is (-6, -2)
