What is the slope for 3y+6x=9
Answer:
The slope is -2!
Step-by-step explanation:
Lets Solve!
3y +6x = 9
First we subtract 6x from both sides
3y = -6x + 9
Next we divide by 3 from both sides.
y = -2x + 3
The slope is -2!
It takes 16 beads to make 4 bracelets. What is the constant of proportionality that relates the number of bracelets made, y, to the number of beads used, x?
Answer:
4
Step-by-step explanation:
Given that:
Number of beads used to make 4 bracelets = 16
Number of bracelets made = [tex]y[/tex]
Number of beads used = [tex]x[/tex]
To find:
The constant of proportionality = ?
Solution:
Number of bracelets made is proportional to Number of beads.
i.e.
[tex]y \propto x[/tex]
OR
[tex]y=k\times x[/tex]
Where [tex]k[/tex] is the constant of proportionality.
We are given that:
when [tex]x = 12, y = 4[/tex]
Putting the values in the above equation:
[tex]4 = k \times 16\\\Rightarrow \bold{k = 4}[/tex]
Therefore, the constant of proportionality is 4.

Piper is at the grocery store and plans on buying cans of soup and frozen dinners, but
is concerned about their sodium content. Each can of soup has 150 mg of sodium and peach frozen dinner has 450 mg of sodium.
How many milligrams of sodium are there in 4 cans of soup and 2 frozen dinners?
How many milligrams of sodium are there in c cans of soup and f frozen dinners?
Answer:
1,500 mg
150c + 450f
Step-by-step explanation:
Each can of soup has 150 mg of sodium and each peach frozen has 450 mg of sodium.
Piper plans to buy some of each product and wants to know how many milligrams of sodium are there in 4 cans of soup and 2 frozen dinners.
Since each can of soup has 150 mg of sodium, 4 cans have 4*150 = 600 mg of sodium.
Each frozen dinner has 450 mg of sodium, thus 2 of them have 2*450 = 900 mg of sodium.
There are 600 + 900 = 1,500 mg of sodium in this combination.
If Piper buys c cans of soup and f frozen dinners, they will have 150c + 450f milligrams of sodium.

P(A) = 2/5 P(B) = 1/2 P(A or B) = 9/10
9514 1404 393
Answer:
mutually exclusive
Step-by-step explanation:
The formula of interest is ...
P(A or B) = P(A) + P(B) - P(A and B)
Filling in the given values, we have ...
9/10 = 2/5 + 1/2 - P(A and B)
Solving for P(A and B), we get ...
P(A and B) = 2/5 +1/2 -9/10 = 4/10 +5/10 -9/10
P(A and B) = 0
__
Events are mutually exclusive when they can never happen at the same time. That is, P(A and B) = 0.
The events A and B are mutually exclusive.

Una persona ahora en el banco 1000 pesos, el cual le ofrece un interés fijo de 3%. La función que relaciona el dinero ahorrado que recibirá después de x meses de ahorro
Answer:
Interes= [Principal*(1+tasa de interes)^x] - Principal
Step-by-step explanation:
Dada la siguiente información:
Principal= $1,000
Tasa de interes= 3% anual = (0.03/12)= 0.0025 mensual
Número de periodos= x
Para calcular el interés ganado, hay que usa la formula siguiente:
Interes= [Principal*(1+tasa de interes)^x] - Principal
Por ejemplo, para 6 meses:
Interes= [1,000*(1.0025^6)] - 1,000
Interes= $15.09

The selling price of an item is $480. It is marked down by 10%, but this sale price is still marked up from the cost of $. Find the markup from cost to sale price.
Answer:
Markup = [(Revenue – COGS) / COGS] X 100.
Markup = (Gross Profit / COGS) X 100.
Markup = [(Revenue – COGS) / COGS] X 100.
Markup = [($400 – $250) / $250] X 100.
Selling Price = [(Markup X COGS) + COGS] X 100.
Selling Price = (Markup X COGS) + COGS.
Selling Price = (0.50 X $100) + $100.

The dimensions for a rectangular prism are x + 7 for the length, x + 9 for the width, and x for the height. What is the volume of the prism? Enter your answer as a polynomial in standard form. The volume of the prism can be expressed as _____.
Answer:
The volume of the prism is x^3 + 16x^2 + 63x
Step-by-step explanation:
Mathematically, the volume of the prism is the area of the base multiplied by the height of the prism
The area of the base is l * w
= (x + 7)(x + 9) = x^2 + 7x + 9x + 63 = x^2 + 16x + 63
The volume is now; x(x^2 + 16x + 63)= x^3 + 16x^2 + 63x
How to use distributive property to find 12 + 20 ?
Answer:
The distributive property states that
a*(b + c) = a*b + a*c
You can use the distributive property in reverse to factor out a common factor from the sum of 2 numbers. If you realize that 12 = 4*3 and 20 = 4*5 then you can write
12 + 20 = 4*3 + 4*5 = 4*(3 + 5)
In a survey of 2,800 people who owned a certain type of car 1,120 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
40% were satisfied

2,800 surveyed
1,120 promised to buy that car again
Assuming that this promise show they are satisfied with the car
2,800. and 1,120
100% x%
crossmultipy and solve
x=100*1,120/2,800=40

Zara has a collection of 4 marbles: an Aggie, a Bumblebee, a Steelie, and a Tiger. She wants to display them in a row on a shelf, but does not want to put the Steelie and the Tiger next to one another. In how many ways can she do this?
Answer:
Step-by-step explanation:
Oops I meant "there are 3! = 6 ways to permute ABTS that have TS."
There are 12 different combinations to display marvel that doesn't involve Steelie and the tiger.
What are permutation and combination?A permutation is an orderly arrangement of things or numbers. Combinations are a means to choose items or numbers from a collection or set of items without worrying about the items' chronological order.
Given, Zara has a collection of 4 marbles: an Aggie, a Bumblebee, a Steelie, and a Tiger. She wants to display them in a row on a shelf but does not want to put the Steelie and the Tiger next to one another.
We want the number of ways to permute the string ABST that has S and T separated.
Total ways of displaying marbles = 4! = 24
If S and T are together, then the permutation contains the consecutive pair ST or TS somewhere. We can count these possibilities by regarding ST or TS as a single symbol
permutation of getting them together = 2 * 3!
permutation of getting them together = 12
Thus,
total desired combination = Steelie and tiger do not come together
total desired combination = 24 - 12 = 12
therefore, There are 12 possible combinations of displaying marvel without making Steelie and tiger together.

The cubic polynomial below has a double root at x=-4 and one root at x=6 and passes through the point (2,36) as shown. Algebraically determine it’s equation in factored form.
Answer: P(x) = (-1/4)*(x + 4)*(x + 4)*(x - 6)
Step-by-step explanation:
The factored form of a polynomial is:
P(x) = A*(x - r₁)*(x - r₂)*(x - r₃)....
Where:
A is a real number.
r₁, r₂,.... etc
are the roots.
In this case, we know that the roots are:
-4, -4, and 6.
Then the polynomial will be:
p(x) = A*(x + 4)*(x + 4)*(x - 6)
Now we also know that this polynomial passes through the point (2, 36)
This means that:
P(2) = 36 = A*(2 + 4)*(2 + 4)*(2 - 6) = A*6*6*(-4) = A*(-144)
36 = A*(-144)
-36/144 = A
-0.25 = -1/4 = A
Then the polynomial is:
P(x) = (-1/4)*(x + 4)*(x + 4)*(x - 6)

What two consecutive integers have a sum of 39?
19 & 20 are the reqd. integers.
By what is given, x + ( x + 1 ) = 39 .
∴ 2 x + 1 =39.
∴ 2 x = 39 − 1 = 38 .
∴ x = 19 , so, x + 1 = 20 .
Thus, 19 & 20 are the reqd. integers.
