Answer: 12/7
Step-by-step explanation: The answer is 12/7 because here is what we know: A group of friends collected toys to donate to children in need. After sorting the toys into boxes, that's what we know, we also know that they found they had 6/7 of a box of stuffed animals, and we also know that they found 5/7 of a box of board games and
1/7 of a box of doll. What they want to know is In total, how many boxes of toys did the friends collect? so you take 6/7 from the box stuffed animals they found + 5/7 from the box of board games they found which equals 11/7 then you add the 11/7 with the 1/7 the box of dolls they found. In total the friends collect 12/7 boxes. Hope this helps!

What are Matrices?
Matrices, the plural form of a matrix, are the arrangements of numbers, variables, symbols, or expressions in a rectangular table that contains various numbers of rows and columns. They are rectangular-shaped arrays, for which different operations like addition, multiplication, and transposition are defined. The numbers or entries in the matrix are known as its elements. Horizontal entries of matrices are called rows and vertical entries are known as columns.
We have given,
the matrix:
[tex]T = \left[\begin{array}{cc}4&2\\5&0\\11&-1\\8&3\end{array}\right][/tex]
To find the denotation of the element 0,
so,
A matrix is the arrangement of numbers in rows and columns in order to form an array.
The horizontal arrangement is called a row and the vertical arrangement is called a column.
If the matrix is denoted as [tex][T]_{m \times n}[/tex] it means that the matrix T has m rows and n columns and the order of the matrix is m × n.
Each number in the matrix is called an element and the position of the element is represented as [tex]a_{mn}[/tex].
Representation of the standard matrix is:
[tex]A = \left[\begin{array}{ccc}a_{11}&a_{12}&........ a_{1n}\\a_{21}&a_{22}&........a_{2n}\\\\a_{m1}&a_{m2} &........a_{mn}\end{array}\right]_{m \times n}[/tex]

a. x and y-intercepts.
b. symmetries (if any) about the x-axis, the y-axis, and the origin.
When (a, b) appears on a graph, it is said to be symmetric around the x-axis if (a ,b) also appears there at the same time. A graph that is symmetric around the x-axis is shown in the following illustration. A graph is said to be symmetric around the y-axis if and only if (a ,b) and (a, b) are both present on it.
We replace all the x's with -x and check to see if we get an equivalent formula to determine algebraically whether a graph is symmetric with regard to the y axis. Example: A) To make y = x2 symmetric with regard to the y axis, we substitute y = (-x)2 = x2 for y = x2.
Ordered pairs (x, y) and and exist in equations or functions that are symmetric to the origin (-x, y). The original equation is symmetric with respect to the origin if you swap -x for x and -y for y in the equation and simplify.
If we reflect a function's graph about the y-axis, we will get the same graph since some functions might be symmetrical about the y-axis. We may reflect various functions about the x- and y-axis and obtain the same graph. These two symmetry kinds are known as even and odd functions.

What is graph?
In discrete mathematics, a graph is made up of vertices—a collection of points—and edges—the lines connecting those vertices. In addition to linked and disconnected graphs, weighted graphs, bipartite graphs, directed and undirected graphs, and simple graphs, there are many other forms of graphs.
A simple graph is one in which no two vertices are connected by more than one edge, and no edge begins or finishes at the same vertex. In other terms, a simple graph is one that doesn't have loops or many edges.
Reflection in the x axis will convert all positive values of f(x) to negative values of f(x) and vice versa.

Having sides that are parallel to one another, a parallelogram is a two-dimensional geometric shape. It is a sort of four-sided polygon (sometimes known as a quadrilateral) where each parallel pair of sides is the same length.
What is the parallelogram?With two sets of parallel sides, a parallelogram is a quadrilateral. A parallelogram has equal-length opposing sides and equal-size opposing angles. Also supplementary to the transversal are the interior angles on the same side. A 360 degree circle is formed by adding together all inside angles.Parallelepiped is the name given to a three-dimensional shape with parallelogram-shaped faces. The base, which is one of the parallel sides, and height, which is the distance from top to bottom, both affect the parallelogram's size. The lengths of the four sides determine a parallelogram's perimeter.Parallelogram-like characteristics can also be found in the shapes of a square and a rectangle.AB || CD and AD || BC form a parallelogram in the preceding illustration, which shows that ABCD.In addition, AB = CD and AD = BC.

b. Prove the equivalence of the two expressions using algebraic manipulation.
Answer:
The two expressions are equivalent, based on a direct numerical comparison (a) and (b) a methematical comparison.
Step-by-step explanation:
a) The expressions can be shown to be equivalent by entering the numbers into each expression and comparing the results. This is easy with a spreadsheet program. Set up a table with the values of x in the left column. Then enter the 2 equations in the first entry (-2) in each of two subsequent columns. These expressions can be copied to the other rows by clicking on the first cell and dragging the lower right corner down until all rows are included. The copied expressions will select the corresponding value of x for both expressions, as shown in the attached table. It can be seen that both expressions yield the same results.
b) Prove the equivalence mathematically:
In other words, do the two expressions equal each other?
(12x^2 - 27)/3 = -(-2x+3)(2x+3) ??
Simplify both sides
(4x^2 - 9) = -(-4x^2 + 9) ?

The Marching Band is traveling from Minnesota to Florida to perform in a national competition. A train ticket from Minnesota to Florida costs $150 and takes 15 hours of travel time per student. To rent a bus to make the trip, it costs $120 per student and takes 20 hours of travel time per student. The band has $4,800 to spend on the trip and can only spend 720 hours of total travel time. Use the information below.
Let x = Students traveling by train
Let y = Students traveling by bus
Therefore,
$150x + $120y < $4,800 and
15x + 20y < 720.
The graph of these functions is to the right.
It is impossible for a negative number of students to go on the trip, so x and y both have to be greater than zero. Therefore, the functions are confined to the first quadrant.
Number of students function:
N = x + y
The number of students travelled by bus and train are 38.

What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Let x = Students traveling by train
Let y = Students traveling by bus
Now equations to represent the situation is
150x+120y=4,800 and 15x+20y=720
30(5x+4y)=4,800
5x+4y=160 ----------(I)
15x+20y=720
3x+4y=144 ----------(II)
Subtract equation (II) from (I), we get
5x+4y-(3x+4y)=160-144
⇒ 2x=16
⇒ x=8
Substitute x=8 in equation (I), we get
5(8)+4y=160
⇒ 4y=120
⇒ y=30
Number of students =38

Kareem cannot decide which of two washing machines to buy. The selling price of each is $550. The first is marked down by 30%. The second is marked down by 20% with an additional 10% off. Find the sale price of each washing machine. Use pencil and paper. Explain why Kareem should buy the first washing machine rather than the second if the machines are the same except for the selling price.
Answer: Because the first washing machine is cheaper
Step-by-step explanation:
Find the first washing machine price by taking 550 times 0.7 = $385
The second machine is first down by 20%, so take 550 times 0.8 =$440
Then 10% off, so take 440 times 0.9 = $396
So the first washing machine is cheaper than the second one $11
