System of Equations Part
You can plug these (x,y) values in one of the equations to see if it is true.
a. (1,2)
b. (0,-4)
c. (3,7)
Answer:
A=B maybe ...
what is that symbols of a and b
Let denote the <em>k</em>th term of the sequence. Then
where <em>d</em> is the common difference between consecutive terms in the sequence and <em>a</em>₁ is the first term.
The sum of the first <em>n</em> terms is
From the formula for , we get
So we have , and so that .
Then the <em>n</em>th term in the sequence is
4/5 = 12/15
1/3 = 5/15
17/15 = 1 2/15
Answer:
y I z
Step-by-step explanation:
We can see that y I b and z I b we can conclude also that
y I z.
