Answer:
A = 15x³[tex]y^{4}[/tex]
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = length × breadth
= 3x²y² × 5xy²
= 3 × 5 × x² × x ×y² × y²
= 15 × x³ × [tex]y^{4}[/tex]
= 15x³[tex]y^{4}[/tex]

What is the word for added and subtracted parts of an expression
The word for added and subtracted parts of an expression is known as the term.
What is an expression?An expression in math is an arithmetic set of numbers and variables with signs and calculations. For example, 4x - 2x = 2x is an expression. The parts that are connected with addition or subtraction or other signs are called terms.
Terms that have the same base exponent can be joined with addition and subtraction. These are called like terms. For example, 3 x 3 and 5 x 3 are like terms.
Therefore, the term is the term for the added and removed components of an equation.

What is the function g(x) that What is the results when translating the function f(x)=x to the left 12 units and reflecting it over the x-axis?
g(x) =
The function g(x) that results when translating the function f(x)=x to the left 12 units and reflecting it over the x-axis is g(x) = -|x + 12|
Translating to left ≡ f(x + 12)
Translation up 12 units means g(x)=f(x)+5g(x)=f(x)+5. Reflecting this across the x-axis means g(x)=-(f(x)+12)g(x)=−(f(x)+12)
-(x+12)=-x-12
f(x + 12) = |x + 12|
Reflection of a function f(x) about the x - axis is keeping the x value same but negating the y values
Reflected f'(x) = -y = -f(x)
Taken together
g(x) = -(|x + 12|)
The function g(x) that results when translating the function f(x)=x to the left 12 units and reflecting it over the x-axis is g(x) = -|x + 12|

The set of, S - T = {3, 9}
Define Set Operation.
To obtain a combination of components according to the operation done on them, the set operations are conducted on two or more sets.
In a set theory, there are three major types of operations performed on sets, such as:
1) Union of sets (∪)
2) Intersection of sets (∩)
3) Difference of sets ( – )
We know, S -T = S ∩ T'
Given, universal set is U = {1, 2, 3, ..., 10}
S = {3, 5, 7, 9} and T = {4, 5, 6, 7}
Now, find T' (T's compliment),
The complement of set T is defined as a set that contains the elements present in the universal set but not in set T.
T' = {1, 2, 3, 8, 9, 10}
given, S = {3, 5, 7, 9}
Find, S ∩ T'
S ∩ T' = {3, 5, 7, 9} ∩ {1, 2, 3, 8, 9, 10}
The intersection of two sets S and T is a subset of the universal set U and contains elements that are present in both sets S and T. It is represented by the symbol "∩".
so, S ∩ T' = {3, 9}
Hence, S - T = S ∩ T' = {3, 9}

In elimination method, the equation is multiplied by some constant and then add/subtract the equations to eliminate any variable x or y.
multiplying equation(i) by 2 we get
6x+2y=12 ....(iii)
subtracting , the equation (ii) from equation (iii) , we get
(6x+2y) - (-8x+2y) = 12-(-2)

x +3 +7 = 2x -10 -x how many solutions does it have
Answer:
no solution
Step-by-step explanation:
x + 3 + 7 = 2x + 10 - x ( simplify both sides )
x + 10 = x - 10 ( subtract 10 from both sides )
x = x - 20 ( subtract x from both sides )
0 = - 20 ← not possible

George is putting trim around the rectangular deck, this means that he is surrounding the deck's perimeter with trim.
You know that he needs 50ft of trim to do the entire deck, this value represents the perimeter of the rectangular deck, and the length of the deck is 15ft.
Knowing the perimeter (P) and the length (l) of the rectangular deck, you can calculate the width (w) of the deck.
The formula for the perimeter of the rectangle is:
[tex]P=2l+2w[/tex]Write the formula for w:
[tex]\begin{gathered} P=2l+2w \\ P-2l=2l-2l+2w \\ P-2l=2w \\ \frac{P-2l}{2}=\frac{2w}{2} \\ w=\frac{P-2l}{2} \end{gathered}[/tex]Use P=50ft and l=15ft to calculate the width:

The equation y = 7/4x - 1 is in slope-intercept form, with a slope of 7/4 and a y-intercept of -1.
To graph it, you need to locate the point (0, -1) - the y-intercept -, and then use the slope to find another point. From (0, -1) you have to move 4 units to the right, and 7 units up, reaching the point (4, 6). Then, you have to draw the line that passes through theses points, as follows:

What is domain and range?The domain of a function refers to the set of values that we are allowed to enter into our function.
The set of values that a function can accept as input is known as its range. Once we enter an x value, the function returns this list of values , the y values are these.
The range and domain must be understood to be all the values that the variable y can represent, respectively, and the x values.
Since the ordered pairs have the form (x,y), we can determine the values of x and y.
The x and y values of function are:
F(x,y) = (2,8), (4,6), (6,4), (8,2), (10,0), (12,2), (14,4)

To find the greates number of bouques he can make, we need to find the greatest number that divdes the three numbers: 45, 27 and 18.
45 can be divided by the following numbers:
1,3,4,5,9,15,45
27 can be divided by the following numbers:
1,3,9,27
18 can be divided by the following numbers:
1,2,3,6,9,18
From the divisors of the three numbers we can see that the greatest number that divide the three of them is 9.
Thus, 9 is the greatest number of bouquets he can make using at leat 1 of each. Also those 9 bouquets would have all the same arrengement.
Answer: 9

Find the coordinates of the vertices of each figure after the given transformation REFLECTION ACROSS y=-x

A reflection in mathematics is a mapping from a Cartesian coordinates to itself which is an isometry with such a set of fixed points known as the hyperplane, also known as the axis or plane of reflection.
The mirror image of a figure in the axis or plane of reflections is the image produced by a reflection. For instance, the minuscule Latin letter p would appear like the letter q when reflected with regard to a vertical axis. It would appear like b when reflected on a horizontal axis. Every object goes back to its original place and every geometric object is returned to its initial condition when a reflection is applied twice consecutively.We know that when a figure is reflected along the line y = -x then the coordinates change their places and they are negated.

The Slope-Intercept form of the equation of a line is:
[tex]y=mx+b[/tex]Where "m" is the slope of the line and "b" is the y-intercept.
Given the equation of the line "g":
[tex]y=-10x-2[/tex]You can identify that:
[tex]\begin{gathered} m_g=-10 \\ b_g=-2 \end{gathered}[/tex]By definition the slopes of perpendicular lines are opposite reciprocals. Then, the slope of the line "h" is:

The magnification of the system with an object distance of 5 cm and an image distance of 15 cm is 0.33.
A lens is a transmissive optical tool that employs refraction to focus or disperse a light beam.
In optics, magnification refers to the image's size in relation to the item that produced it. The ratio of the image length to the object length, as measured in planes perpendicular to the optical axis, is referred to as linear magnification, also known as lateral or transverse magnification.
The size of an object is u = 5 cm
The size of the image formed by the lens is v = 15 cm
Then the magnification M will be:
Magnification = Image distance/ Object distance
M = v/u
M = 5/15
M = 1/3
M = 0.33
Hence, the magnification of the system is 0.33.
