Find an explicit formula for the arithmetic sequence -15, 13, 31, 49

Answers

Answer 1

Answer:

No solution (read below)

Step-by-step explanation:

Formula:

a_n = a_1 + (n-1)d

N is the term #

D is the common difference

First, let's find the common difference.

13 - (-15) = 28

Let's see if that checks out.

31-13 = 18

49 - 31 = 18

18 is not equal to 28

Since there is no common difference you cannot find the equation.

Please tell me if you made a typo and comment on my answer, then I can help you find the answer

Answer:

Factored Form: f(x) = (x-7)(x-4)

Roots: x=7, x=4

Step-by-step explanation:

What  we can do here is break the given expression into groups;

x^2-11x+28 ---> break the expression into groups

(x^2-4x) +(-7x+ 28) ---> factor out x from x^2-4x

x(x-4) + (-7x +28) ---> factor - 7 from -7x +28

x(x-4) -7(x-4) ---> combine

(x-7)(x-4)

so if f(x) = (x-7)(x-4) then the roots would be x=7 and x=4

A group of friends is sharing 212 pounds of berries. If each friend received 54 of a pound of berries, how many friends are sharing the berries? If 5 friends are sharing the berries, how many pounds of berries does each friend receive?

Answers

Answer:

Number of friend = 4 friends (Approx)

Amount of berries each friend get = 42.4 pound

Step-by-step explanation:

Given:

Total amount of berries = 212 pound

A. Number of friend

Number of friend = 212 / 54

Number of friend = 4 friends (Approx)

B. Amount of berries each friend get

Amount of berries each friend get = 212 / 5

Amount of berries each friend get = 42.4 pound

You have gone out to eat with a couple of friends. One is your friend Jamal and the other is your friend Marek. At the end, you get the check, and you decide to split it in two parts. You will pay for yourself and Jamal, while Marek will pay for 1/3 of the total amount. You end up paying $16.00 for your part of the meal. Later, you can’t remember how much the total bill was, but you are sure you can figure it out.



1. Write a system of equations to represent this situation, and solve the system to find out how much the total cost of the meal was (including your part as well as Marek’s part). Show all of your work.



2. How much did Marek pay for his part of the meal? Again, show all of your work.



3. Was this a fair way to split up the check? What might be a more fair way to split up the check?

Answers

1: 48


2: 1/3 of 48 = 48/3 = 16


3:No it wasn’t because you payed an extra 16 for jamals meal.Everyone should pay 16 dollars each because that is 1/3 of the meal price

Which is the function that gives the amount of money m that Margaret has as a function of the number of rides that she takes?
Om = 3r +35
Om = 35r - 3
Om = 35r +3
Om = -3r + 35

Answers

Answer:

Om= -3r+35

Step-by-step explanation:

If she pays 3 dollars for a ride then that means she is subtracting 3 dollars from the amount she had which is 35. So it would be -3 times the amount of rides she rode plus 35. Hope this helped you!! Give brainliest.

Answers

Answer:

8 units

Step-by-step explanation:

The two squares have equal areas.

For each square:

area = 32 units^2

For a square:

area = side^2

side^2 = 32

side = sqrt(32)

For the two squares, the length of the side is sqrt(32).

The sides of the squares are the legs of the right triangle.

a^2 + b^2 = c^2

(sqrt(32))^2 + (sqrt(32))^2 = x^2

32 + 32 = x^2

x^2 = 64

x = 8

Answer: 8 units

Answer

8 units

Explanation

The side of one of the squares is the same length as one of the legs on the triangle.

To find one side of the square, you need to find the square root, because to find the area of a square, you need to square the sides. To find one side, you do the opposite.

So the length of one side is the square root of 32.

Now don't worry that this is a weird number (which is 5.656854249...) because we'll be squaring it again.

The length of one side of the square is the leg of a right triangle.

To find the hypotenuse (or the longest side), you need to use the Pythagorean theorem.

[tex]l^{2} + l^{2} = h^{2}[/tex]

The square root of 32 squared is 32.

[tex]32+32=h^{2}[/tex]

[tex]64=h^{2}[/tex]

To find h, you need to find the square root. The square root of 64 is 8.

Therefore, the length of x is 8 units.

The answer is the first option that states that you can write this expression as [tex]7(\frac{x}{8}) + \frac{3}{4} = -6[/tex]

Step-by-step explanation:

In order to solve this question we will need to know how to factor fractions. In our case we can do the following.

[tex]\frac{7}{8}x = \frac{7x}{8} = 7(\frac{x}{8})[/tex]

So now we since [tex]\frac{7}{8} x= 7(\frac{x}{8} )[/tex] ⇒

the Astros jersey increased?

Answers

Answer:

50%

Step-by-step explanation:

The cost = $80

Increased cost = $120

% Increase = (120-80) / 80 * 100

% Increase = 40/80 * 100

% Increase = 0.5 * 100

% Increase = 50%

So, the price of the Astros jersey increased by 50%

x = (600*1)/0,15

x = 600/0,15

x = 4000

Answer:

f(2) = -3

Step-by-step explanation:

This is the answer because:

1) The question is basically asking what the y-cordinate is.

2) In order to find the y-cordinate, look at the graph and find where 2 is on the x-axis. Then, see wheree the y-coordinate is on the same line a the x-cordinate which is 2.  

3) When you line up the cordinates, you can see that where x is 2, y is -3.

Therefore, the answer is -3.

Answer:

C.) y = 5/4x - 4

Step-by-step explanation:

Points: (0,-4) and (4,1)

m = y2 - y1/x2 - x1

m = 1 + 4/4

m = 5/4

Point: (4,1) (you may choose any points, but I will choose these since they are the easiest to work with)

y - y1 = m(x - x1)

y - 1 = 5/4(x - 4)
