Answer:
A Series is always a periodic sum of terms, so only A and D will apply to that definition
(where A= 1/2 + 1/4 + 1/6 + 1/16 + 3.14159 and B=25 - 5 - 10 - 15 - - 125
3x2+4x=2
6+4x=2
-6 -6
4x=-4
4 4
x=-1
Answer:
The equation to determine the total length in kilometers is 
The total length in kilometers of Josh’s hike is 38 km.
Step-by-step explanation:
Given:
Let the total length in kilometers of Josh’s hike be h.
Now Given that He has now hiked a total of 17 km and is 2 km short of being 1/2 of the way done with his hike.
It means that to reach half of the length of total length Josh needs 2 more km to add in his hiking which is done which is of 17 km.
Framing the above sentence in equation form we get;

Hence, The equation to determine the total length in kilometers is 
Now Solving the above equation we get;
First we will multiply 2 on both side using Multiplication property we get;

Hence, The total length in kilometers of Josh’s hike is 38 km.
Answer:
Step-by-step explanation:
- The first question's slope is 0 because it is a straight horizontal line
- The second question is undefined because it is a straight vertical line
- The third question's slope isn't able to be found with a blank line, but the line is positive because the more it travels right, it also goes up. So the slope of the third is positive
- The fourth is similar to the third as its slope cannot be calculated with a blank line, but the more it moves right, the more it moves down, meaning the slope is negative.
