In an arithmetic sequence, the first term, a_1,a
1 , is equal to 5,5, and the fifth term, a_{5},is equal to 41.41. Which number represents the common difference of the arithmetic sequence?
Answer:
10
Step-by-step explanation:
The general term of an arithmetic sequence is given by ...
an = a1 +d(n -1) . . . . where a1 is the first term and d is the common difference
__
This formula can be used to find the value of d. The first term is given as 1, and the 5th term (a5) is given as 41. The value of n for the 5th term is 5.
an = a1 +d(n -1)
41 = 1 +d(5 -1) . . . . . substitute known values
40 = 4d . . . . . . . subtract 1, simplify
10 = d . . . . . . divide by 4
The common difference of this sequence is 10.

Determine another point on the line given two points on the line. (-2, 9), (2, -1)
Answer:
(4,-6)
Step-by-step explanation:
1) First, let's find the slope of the line between the two points. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], substitute the x and y values of (-2,9) and (2,-1) into it, then solve:
[tex]m = \frac{(-1)-(9)}{(2)-(-2)}\\m = \frac{-1-9}{2+2} \\m =\frac{-10}{4} \\m = -\frac{5}{2}[/tex]
So, the slope of the line is [tex]-\frac{5}{2}[/tex].
2) Now, using that slope, let's find another point on the line. You can do this by drawing the two points on a graph (picture below). Now, remember that the slope is [tex]\frac{rise}{run}[/tex]. So, starting from any of the two points (I chose (2,-1), as seen below) count 5 units down, then 2 units to the right. This gives an answer, (4,-6).

Solve the equation below. Pls include work
28.10 = 15.5 + 5x
Answer:
2.52
Step-by-step explanation:
5x + 15.5 = 28.1
subtract 15.5 from both sides
5x = 12.6
divide both sides by 5
x = 2.52
Answer:
x=2.52
Step-by-step explanation:
28.1 = 15.5 + 5x
(take 15.5 from both sides)
28.1-15.5=15.5-15.5+5x
12.6=5x
(Divide both sides by 5)
12.6/5=5x/5
2.52=x
