The first five terms of an arithmetic sequence are 8, 13/2, 5, 7/2, and 2. Which function, f(x), could be used to describe the xth term of the sequence?
f(x)=?
Answer:
The nth term of the sequence is:
[tex]a_n=\frac{-3n+3}{2}+8[/tex]
Step-by-step explanation:
Given the first 5 terms of the arithmetic sequence
8, 13/2, 5, 7/2, and 2
An arithmetic sequence has a constant difference 'd' and is defined by:
[tex]a_n=a_1+\left(n-1\right)d[/tex]
as the common difference 'd' is:
[tex]d=a_{n+1}-a_n[/tex]
Computing the differences of all the terms
[tex]\frac{13}{2}-8=-\frac{3}{2},\:\quad \:5-\frac{13}{2}=-\frac{3}{2},\:\quad \frac{7}{2}-5=-\frac{3}{2},\:\quad \:2-\frac{7}{2}=-\frac{3}{2}[/tex]
[tex]d=-\frac{3}{2}[/tex]
The first element is:
[tex]a_1=8[/tex]
Therefore, the nth term is computed by:
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_n=-\frac{3}{2}\left(n-1\right)+8[/tex]
[tex]a_n=\frac{-3n+3}{2}+8[/tex]
Therefore, nth term of the sequence is:
[tex]a_n=\frac{-3n+3}{2}+8[/tex]

Step-by-step explanation:
because A<C are the only angle ur missing.
Answer:
DC ≅ AB
Step-by-step explanation:
Because AC ≅ AC is given, I'm gonna assume its DC ≅ AB
I know kind of weird that I'm gonna have to assume when I've given 148 answers and I'm of the rank expert, however I looked at that triangle and all of those answers are correctly proving congruence, so it makes no sense to mark you wrong because technically ALL of the sides are given

Write a system of equations that has a sum of 1 and a difference of 9
Answer:
1 + 0 = 1
100 - 91 = 9
Step-by-step explanation:
What is the value of y in the equation 9 + y = 8? this is extremely time sensitive
You have to switch the 8 to the left and the y to the right which would change the equation to 9-8=y
y=1
Answer: y =-1
Step-by-step explanation:y =-1
Last option is correct.
Step-by-step explanation:
The given equation is
In order to solve for y, we need to isolate y.
In this equation 9 is added with y and hence in order to eliminate 9 from the left hand side, we do reverse operation of addition.
The reverse operation of addition is subtraction. Hence, we subtract 9 to both sides of the equation

Step-by-step explanation:
15 is the y-intercept
-7 is the slope
Answer:
[tex]a_{n}[/tex] = 22 - 7n
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
8 - 15 = 1 - 8 = - 7
This indicates the sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 15 and d = - 7 , then
[tex]a_{n}[/tex] = 15 - 7(n - 1) = 15 - 7n + 7 = 22 - 7n ← explicit formula

If n/8 has a remainder of 5, then which of the following has a remainder of 7?
A) n+1/8
B) n+2/8
C) n+5/8
D) n+7/8
Answer:
[tex]\frac{n+2}{8}[/tex] has a remainder of 7 ⇒ B
Step-by-step explanation:
In m ÷ n = c + [tex]\frac{r}{n}[/tex] ,
m is the dividendn is the divisorc is the quotientr is the remainderm = (n × c) + rLet us use the facts above to solve the question
∵ [tex]\frac{n}{8}[/tex] has a remainder of 5
→ Let us find the first number divided by 8 and give a reminder of 5
that means let the quotient = 1
∵ n = (8 × 1) + 5 = 8 + 5
∴ n = 13
∵ [tex]\frac{n+x}{8}[/tex] has a remainder of 7
→ Let us find the first number divided by 8 and give a reminder of 7
that means let the quotient = 1
∵ n + x = (8 × 1) + 7 = 8 + 7
∴ n + x = 15
∵ n = 13
∴ 13 + x = 15
→ Subtract 13 from both sides
∴ 13 -13 + x = 15 - 13
∴ x = 2
∴ [tex]\frac{n+2}{8}[/tex] has a remainder of 7
A drill is used to dig down into the earth. After 2 hours, the drill is 12 meters below the surface. After 5 hours, the drill is 30 meters below the surface. Which equation represents the depth of the drill in meters, y, after x hours of drilling?
Answer:
6y = x
Step-by-step explanation:
All that equation is saying is that for every 1 hour drilled (x), 6 meters (y) are drilled.
y = distance in meters
x = time
12y = 2x
12y/2 = 2x/2
6y = x
30y = 5x
30y/5 = 5x/5
6y = x
The equation representing the depth of the drill in meters, y, after x hours of drilling is y = -6x
Since the slope is 3, hence it passes through the point (-4.67, 0). Hence the equation of the line is y = 3x + 14.
A linear equation is in the form:
y = mx + b;
where m is the slope, b is the y intercept and y, x are variables.
Let y represent the depth of drill in meters after x hours of drilling. Hence:
Since after 2 hours, the drill is 12 meters below the surface, it can be represented by (2, 12). Also after 5 hours, the drill is 30 meters below the surface, it can be represented by (5, 30)
The equation of the line is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1) \\\\y-(-12)=\frac{-30-(-2)}{5-2}(x-2) \\\\y+12=-6(x-2)\\\\y+12=-6x+12\\\\y=-6x[/tex]
The equation representing the depth of the drill in meters, y, after x hours of drilling is y = -6x

The Bigtown football team outscored its opponents 5:2 last season.
If their opponents scored 38 points, how many points did Bigtown
score?
Step-by-step explanation:
5:2 add to find total ratios 7
opponents=2/7=38
bigtown=5/7=95
Answer: The big town team scored 95 points.
Step-by-step explanation: Given that the big town football team outscored its opponents 5:2 last season and their opponents scored 38 points.
We are to find the points scored by big town team.
Let 5x and 2x represents the points scored by big town team and their opponents.
Then, according to the given information, we have
2r = 38
r = 38/2
r = 19
Therefore, the points scored by big town team is given by
5 X 19 = 95.
Thus, the big town team scored 95 points.
What is the correct answer for both?
Answer:
19) D (-8, -2)
20) B (0, 8)
Step-by-step explanation:
-x - y = 10
-6x + 11y = 26
-x - y = 10
-x = 10 + y
x = -10 - y
-6x + 11y = 26
-6(-10 - y) + 11y = 26
60 + 6y + 11y = 26
60 + 17y = 26
17y = -34
y = -2
-x - y = 10
-x - (-2) = 10
-x + 2 = 10
-x = 8
x = -8
_______________
-x + y = 8
3x + 2y = 16
-x + y = 8
y = 8 + x
3x + 2y = 16
3x + 2(8 + x) = 16
3x + 16 + 2x = 16
5x + 16 = 16
5x = 0
x = 0
-x + y = 8
-0 + y = 8
y = 8
