Answer:
The fifth term is 7
Step-by-step explanation:
Looking at the graph
we have the ordered pairs
(1,5),(2,5.5),(3,6),(4,6.5),(5,7)
so
Let
The common difference in this arithmetic sequence is 0.5
The value of the fifth term is a_5
therefore
The fifth term is 7
Answer: (7,5) X=7 and Y=5
Explanation:
Add the two equations together to eliminate y from the system.
x-y=2 + x+y=12
= 2x = 14
Divide both sides by 2
x=7
Substitute the value found for x into one of the original equations to solve for y
(7)-y=2
Move all terms to one side to make it easier
-y=2-7
Subtract
y=5
