Answer:
interval notation for all numbers except those that are at least -1 and less than 2.
Step-by-step explanation:
The ∪ between the two sets of brackets indicates the "union" of two sets. The brackets on the left indicate the interval ...
-∞ < x < -1 . . . . . for a value represented by x
The curved brackets ( ) indicate the end values of the interval are not included, which is why the < symbol is used, and not the ≤ symbol.
The brackets on the right indicate the interval ...
2 ≤ x < +∞ . . . . . for a value represented by x
The square bracket [ ] is used to indicate the end value is included, which is why the ≤ symbol is used in relation to the end-value 2.
By convention, the interval notation lists the left end of the interval first, and always uses curved brackets for infinity.

OK SO I SOLVED ALL OF THIS: It costs a company $20 per box to make pocket-sized stuffed animals. The company also has a fixed manufacturing cost of $2300. The owners are trying to calculate their cost for making boxes of animals. --Function Rule: c(x) = 20b + 2300.
BUT I NEED HELP WITH THIS!!! Use your function rule to find out how many boxes of stuffed animals can the company manufacture for $5000? SHOW WORK.
basically just show the work to find out what "b" would have to be in order for the answer to be $5,000 i would appreciate it so much :) please help this is due today :(
Answers
Answer:
The company can manufacture 135 boxes of stuffed animals for $5000
Step-by-step explanation:
To find b, substitute $5000 for c(x), so
5000 = 20b + 2300Then subtract 2300 from both sides of the equation, so
5000 (-2300) = 20b + 2300 (-2300)2700 = 20bFinally divide both sides of the equation by 20, so
2700/20 = 20b/20135 = bTo check your answer substitute 135 in as b...
c(x) = 20(135) + 2300c(x) = 5000Vanity Fair was having a blow out sale on shorts and t-shirts. Trevor bought 12 shorts and t-shirts. The shorts were on sale for $12 each and t-shirts were $6 each. Trevor spent $102. how many shorts and t-shirts did Trevor buy? Let x= shorts and y= t-shirts.

Use Newton's Law of Cooling to find the temperature of a substance as a function of time t in minutes that it has spent
cooling off. This relationship is given by, y = ae* +, where c is the temperature of the medium surrounding the cooling
object, a is the difference between the initial temperature of the object and the surrounding temperature, and k is a
constant related to the cooling object. Two samples of the substance were heated in a container of boiling water until their
initial temperatures were both 100° C. The first sample will be cooled by being left out at a room temperature of 24°C,
and the second sample of the substance will instead be cooled off in a refrigerator with an inside temperature of 4° C.
The value of a will equal the difference between each sample's initial temperature and that sample's surrounding
temperature, and the cooling constant of the substance is k = 0.12.

Cora and Cecilia each use chalk to make their own number patterns on the
sidewalk. They make each of their patterns 10 boxes long and line their patterns
up so they are next to each other.
Cora puts o in her first box and decides that she will add 3 every time to
get to the next number.
Cecilia puts o in her first box and decides that she will add 9 every time to
get the next number.
How many times greater is Cecilia's number in the 5th box than Cora's number in
the 5th box? What about the 8th? What predictions can you make about the
relationship between the values in the rest of the pattern?
Answers
Answer:
5th box has 45 for Cecilia and 15 for Cora
8th box has 72 for Cecilia and 24 for Cora
Cecilia's boxes numbers are 3 times of Cora's boxes numbers.
Step-by-step explanation:
This can be completed as follows .
0 1 2 3 4 5 6 7 8 9 10
Cora's boxes 0 3 6 9 12 15 18 21 24 27 30
Cecilia's boxes 0 9 18 27 36 45 54 63 72 81 90
The 5th box has 45 for Cecilia and 15 for Cora which means Cecilia's number is 3 times bigger than Cora's number in the 5th box.
The 8th box has 72 for Cecilia and 24 for Cora which means Cecilia's number is 3 times bigger than Cora's number in the 8th box.
As we see that the difference in numbers is of three times from the beginning to the end. Therefore we conclude that Cecilia's boxes numbers are 3 times of Cora's boxes numbers.

Answer: 8x - 1200
Step-by-step explanation: Because I did the problem
The profit function for Andrew's new product line is P(x) = 5x - 100.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, The profit function P(x), revenue function, R(x), and cost function, C(x), are related by the equation P(x) = R(x) - C(x).
The revenue and cost functions for a new product line at his business are given by these functions. R(x) = 8x and C(x) = 100 + 3x.
Therefore, P(x) = 8x - (100 + 3x).
P(x) = 8x - 100 - 3x.
P(x) = 5x - 100.

Bacteria of species A and species B are kept in a single environment, where they are fed two nutrients. Each day the environment is supplied with 10,560 units of the first nutrient and 31,510 units of the second nutrient. Each bacterium of species A requires 2 units of the first nutrient and 5 units of the second, and each bacterium of species B requires 1 unit of the first nutrient and 6 units of the second. What populations of each species can coexist in the environment so that all the nutrients are consumed each day? Incorrect: Your answer is incorrect. Of species A
Answers
Answer:
We require 4,550 of species A and 1,460 of species B that can coexist in the environment so that all the nutrients are consumed each day
Step-by-step explanation:
Let n₁ be the population of A required and n₂ be the population of B required.
Now we require 2 units of the first nutrient for species A and one unit of the first nutrient for species B. The total nutrients required by species A is 2n₁ and that by species B is 1n₂ = n₂. So, the total nutrients required by both species A and B is 2n₁ + n₂. Since this equals the quantity of the first nutrient which is 10,560, then 2n₁ + n₂ = 10,560 (1)
Now we require 5 units of the second nutrient for species A and 6 units of the second nutrient for species B. The total nutrients required by species A is 5n₁ and that by species B is 6n₂. So, the total nutrients required by both species A and B is 5n₁ + 6n₂. Since this equals the quantity of the first nutrient which is 31,510, then 5n₁ + 6n₂ = 31,510 (2).
So, we have two simultaneous equations which we would solve to find the populations of A and B which satisfy both equations.
2n₁ + n₂ = 10,560 (1)
5n₁ + 6n₂ = 31,510 (2)
From (1) n₂ = 10,560 - 2n₁ (3)
Substituting equation (3) into (2), we have
5n₁ + 6(10,560 - 2n₁) = 31,510
expanding the brackets, we have
5n₁ + 63,360 - 12n₁ = 31,510
collecting like terms, we have
5n₁ - 12n₁ = 31,510 - 63,360
simplifying, we have
- 7n₁ = -31,850
dividing both sides by -7, we have
n₁ = -31,850/-7
n₁ = 4,550
Substituting n₁ = 4,550 into (3), we have
n₂ = 10,560 - 2(4,550)
n₂ = 10,560 - 9,100
n₂ = 1,460
So, we require 4,550 of species A and 1,460 of species B that can coexist in the environment so that all the nutrients are consumed each day
Number of Bacteria A and Bacteria B = 4550 and 1460 respectively,
Let the number of bacterias of Specie A and Specie B be = x and y respectively.
Given : 2 Nutrient Requirements of both species of Bacteria A and B , Total Nutrients available
To find : Number of Bacteria 1 and Bacteria 2
Nutrient 1 Constraint Equation : 2x + y = 10560
Nutrient 2 Constraint Equation : 5x + 6y = 31510
Putting the value of y from 1st equation in 2nd equation ;
5x + 6 (10560 - 2x) = 31510
5x + 63360 - 12x = 31510
63360 - 31510 = 7x
7x = 31850
x = 31850 / 7 = 4550 { Bacteria A}
Putting the value of x in 1st equation,
2 (4550) + y = 10560
9100 + y = 10560
y = 10560 - 9100 = 1460 {Bacteria B}
