Which of the following is a Recursive Formula for an Arithmetic Sequence?
a1 = -2, an = an-1 + 5
an = 5n – 7
a1 = -2, an= 5an-1
an = -2 + 5(n – 1)
Answers
Answer:
The correct answer is Option 1: a1 = -2, an = an-1 + 5
Step-by-step explanation:
A recursive formula is a formula that uses previous term in order to calculate the next term in a sequence.
In case of arithmetic sequence, the next term is obtain by adding a specific number to the last term.
This can be written as:
[tex]a_n = a_{n-1}+d[/tex]
Here
a_n is the terms we are calculating
a_{n-1} is the previous term and d is the common difference.
If we compare the given options, we can see that only option 1 matches with the general form of recursive formula
an = an-1 + 5
Here
5 is the common difference
Hence,
The correct answer is Option 1: a1 = -2, an = an-1 + 5

What is −3x+4y=−16 in slope-intercept form?
Answers
Answer:
y=3/4x-4
Step-by-step explanation:
First you put x to the other side of the equation, so you have 4y = 3x-16. Next you need to get y alone so you get 4y/4=y. But, you need to do this to both sides of the equation, so you do 3x-16/4=3/4x-4. All in all, your slope-intercept form is y=3/4x-4.
Find the length of side x in simplest radical form with rational denominator. the short leg is root 2 and the long leg is x we don't know the hypotenuse.
Answers
Answer:
√2 + x
Step-by-step explanation:
To obtain the hypotenus, h:
Using Pythagoras rule :
h² = opposite² + Adjacent²
Opposite = √2
Adjacent= x
h² = (√2)² + x²
Take the square root of both sides
h = √2 + x
Hence, the hypotenus is √2 + x

The complete table is shown below:
Graph Vertical Change Horizontal Change Slope
A 6 3 2
B 2 8 1/4
C 40 20 2
Step-by-step explanation:
Graph A
From graph A, it is clear that
(x₁, y₁) = (1, 3)
(x₂, y₂) = (4, 9)
Vertical change = y₂ - y₁ = 9 - 3 = 6
Horizontal change = x₂ - x₁ = 4 - 1 = 3
Using the formula
Slope = m = Vertical Change / Horizontal Change
= [y₂ - y₁] / [x₂ - x₁]
= [9 - 3] / [4 - 1 ]
= 6 / 3
= 2
Thus, the slope of the line = m = 2
Graph B
From graph B, it is clear that
(x₁, y₁) = (2, 1.5)
(x₂, y₂) = (10, 3.5)
Vertical change = y₂ - y₁ = 3.5 - 1.5 = 2
Horizontal change = x₂ - x₁ = 10 - 2 = 8
Using the formula
Slope = m = Vertical Change / Horizontal Change
= [y₂ - y₁] / [x₂ - x₁]
= [3.5 - 1.5] / [10 - 2 ]
= 2 / 8
= 1/4
Thus, the slope of the line = m = 1/4
Graph C
From graph C, it is clear that
(x₁, y₁) = (10, 35)
(x₂, y₂) = (30, 75)
Vertical change = y₂ - y₁ = 75 - 35 = 40
Horizontal change = x₂ - x₁ = 30 - 10 = 20
Using the formula
Slope = m = Vertical Change / Horizontal Change
= [y₂ - y₁] / [x₂ - x₁]
= [75 - 35] / [30 - 10 ]
= 40 / 20
= 2
Thus, the slope of the line = m = 1/4
Therefore,

Area= 4.3^2
Area= 18.49 yard
cost of carpet
1 yard= $28.60
18.49 yard= x

Step-by-step explanation:
ps being the shorter side is one third of the line JS and 1/3 of 27 is 9
jp being the longer side is 2/3 the length of js and 2/3s of 27 is 18
Answer:
JP=18
PS=9
Step-by-step explanation:
centroid divides median in the ratio 2:1
so,
JP:PS=2:1
Now take PS be x
then JP=2x
now, given JS=27
JP+PS=27
2x+x=27
3x=27
x=9
so,
PS=9
AND JP=18
what is the Y interpret of the question? y=-1/2x-6
Answers
Answer:
The y-intercept is (0,-6)
Step-by-step explanation:
In the equation y = mx + b, b is the y-intercept. In your equation, the b is -6, so the y-intercept is (0,-6).
Answer:
Y-intercept: (0, -6)
Step-by-step explanation:
We have to determine the "y-intercept" in the equation.
The equation is written out in slope-intercept form: y = mx + b
The "b" variable would be our y-intercept, or beginning point.
In the y = -1/2x-6 equation, you would see that the "-6" is in place of the "b" variable.
Therefore, the y-intercept of the line would be (0, -6).
Jackson spent 2/3 of his money on an antique game. He has a third of his money left which is $15.50. If he spent 2/3 of his money on the jacket, how much did he spend?
Answers
Answer:
$41.33
Step-by-step explanation:
Let the money be x
Game cost = 2/3*x
balance= 1/3*x
x/3= 15.5
Solve for x
x= 15.5*3
x=$46.5
so his money was $46.5
Amount spent on Game
=2/3*46.5
=$31
He spent 2/3 of 15.5 on Jacket
=2/3*15.5
=$10.33
In all he spent =31+10.33 =$41.33
