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.

Find the coordinates of the vertices of each figure after the given transformation REFLECTION ACROSS y=-x
The coordinates of the vertices after the reflection are V'(-3,2), U'(0,-2), W'(-1,3) and T'(1,2) .
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.

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

On solving the system of equation using elimination method , the value of x is 1 and value of y is 3 .
in the question ,
the two equations are given as
3x+y=6 ...(i)
and
-8x+2y= -2 ...(ii)
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)
6x+2y+8x-2y = 12+2
14x = 14
x = 1
We eliminate 'x' from equation (ii) by replacing the value of 'x' with 1 ,

Use the appropriate form of the percentage formula.What percent of 14.4 is 11.7? Round to the nearest hundredth of a percent.
Hello there. To solve this question, we'll have to compare the values with two fractions:
To see how much of 14.4 is 11.7, in percentage, we start by considering 14.4 represents 100%, or 100, since we want to find the answer in percent as well.
Then we make:
[tex]\frac{11.7}{x}=\frac{14.4}{100}[/tex]Cross multiply the numbers:
[tex]11.7\cdot100=14.4\cdot x[/tex]Divide both sides of the equation by a factor 14.4
[tex]x=\frac{11.7\cdot100}{14.4}[/tex]Using a calculator, we get that x is equal to:
[tex]81.25[/tex]Therefore, 11.7 is 81.25% of 14.4!

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|)

A man sold 4 times as many tie dyed T shirts as silk screened shirts. He sold 190 shirts altogether. how many tie dyed shirts did he sell?
Answer: 152 tie dyed T shirts
Let the number of dyed T shirts be = x
Let the number of silk screened shirts be = y
He sold sold 4 times as many tie dyed T shirt as screened shirts
Since x = Tie dyed T shirt
Therefore, x = 4y
x = 4y ------------------- equation 1
He sold 190 shirts all together
x + y = 190 ------------ equation 2
Substitute the value of x = 4y into equation 2
4y + y = 190
5y = 190
Divide both sides by 5
5y/5 = 190/5
y = 38
Since x = 4y
x = 4(38)
x = 152 tie dyed T shirts
Therefore, 152 tie dyed T shirts was sold
According to the question, the man sold 4 times as many tie dyed T shirt as silk screened shirt
This implies that for 1 silk screen shirt sold, he would also sell 4 tie dyed T shirt
Since, x = tie dyed T shirt and y = silk screened shirts
Then, x= 4 x y
x = 4y
The man sold 190 shirts altogether
This implies that, he sold a total of 190 of both tie dyed T -shirt and silk screened shirts
Mathematically,
x + y = 190
Since x = 4y
Then, 4y + y = 190

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 "∩".

If the size of an object is 5.0 cm, and the size of the image formed by a lens is 15.0 cm, what is the magnification of the system?
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.

[tex](x-x_0)^2+(y-y_0)^2=R^2[/tex]It is called the equation of a circle with center at
[tex](x_0,\,y_0)[/tex]And radius R.
In the question, it gives us two equations that we might describe the shape of the equation, considering its key features (center, foci, asymptotes, semi-major and semi-minor axes, if applicable).
We have that
[tex](x+4)^2+(y-2)^2=16[/tex]Is the equation of a circle with center at (-4, 2) and radius equal to
[tex]R=\sqrt{16}=4[/tex]For the other equation
[tex](x-2)^2+(y-5)^2=64[/tex]Is also the equation of a circle, with center at (2, 5) and radius equal to
[tex]R=\sqrt{64}=8[/tex]what is the answer use the slope intercept form to graph the equation y=7/4x-1
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:
In the circle below, G is the center, LM Is a diameter, HF intersects the circle at M, and JN intersects the circle at K and L. Useblanks.
HF, JN
1) Examining this question, we can state that a tangent line is the one that "touches" the circle in one single point.
So, in this diagram we can state that the tangent line is HF
2) On the other hand, a secant line crosses the circle in two points at least. So the one that fits in this definition is the line defined by points JN
3) In Euclidian Geometry, a chord is a line segment that connects two points in a circle or curve. Examning the diagram again, we can state that KM is a chord.
