What is the purpose of the ninth?
The purpose of the ninth was to assert the principle that the enumerated rights are not exhaustive and final and that the listing of certain rights does not deny the existence of other rights.
Ninth Amendment:The Ninth Amendment was part of the Bill of Rights added to the Constitution on December 15, 1791. It states that all rights not enshrined in the Constitution belong to the people, not to the US government. In other words, the rights of citizens are not limited to those stipulated in the Constitution. Simply put, the Ninth Amendment declares that the enumeration of certain rights in the Constitution should not be construed as withholding or disrespecting others from people. According to Judge Harry A. Blackman, Roe v. Wade (1973),
, "As we believe, this right to privacy is limited by the Fourteenth Amendment concept of restrictions on individual liberty and government action. The Ninth Amendment to the Constitution contains ample scope, including determining whether a woman should terminate a pregnancy."

In ΔQRS, s = 5.2 inches, ∠S=129° and ∠Q=30°. Find the length of r, to the nearest 10th of an inch.
The length of r is 2.4 inches.
What is the law of sines ?
The law of sines specifies how many sides there are in a triangle and how their individual sine angles are equal. The sine law, sine rule, and sine formula are additional names for the sine law.
Given, In ΔQRS, s = 5.2 inches, ∠S=129° and ∠Q=30°
We know that, The sum of all angles of a triangle is 180°.
So, ∠Q + ∠R + ∠S = 180°
∠R = 180° - 129° - 30°
= 21°
Now, We also know that the law of sines specifies how many sides there are in a triangle and how their individual sine angles are equal.
So, q/Sin Q = r/Sin R = s/Sin S
Or, we can say
r/Sin R = s/Sin S
r/Sin 21° = s/Sin129°
r/Sin 21° = 5.2 / Sin 129°
r = 5.2 × Sin 21°/Sin 129°
= 5.2 × 0.46
= 2.4 inches.

The point (2,-4), (x,y), A, and B all lie on the line. Find an equation relating x and y (Hint: The lope formula)
The point (2,-4), (x,y), A, and B all lie on the line. An equation relating x and y is m(x-2)=y+4.
The points (2, -4), (x, y) are lie on the line.
The slope formula is the vertical change in y divided by the horizontal change in x, sometimes called rise over run. The slope formula uses two points, (x1, y1) and (x2, y2), to calculate the change in y over the change in x. Slope is a ratio that includes how y changes for every unit increase of x.
The slope formula,
m[tex](x_{2}-x_{1})= y_{2}-y_{1}[/tex]
Here, [tex]x_{1} = 2, x_{2}= x, y_{1}= -4[/tex] and [tex]y_{2}= y[/tex]
Now, we have to substitute the values in the formula,
[tex]m=\frac{y-(-4)}{x-2}[/tex]
[tex]m= \frac{y+4}{x-2}[/tex]
m(x-2)= y+4

When a pre-image moves the new shape is called a?
The operation that maps(moves)the preimage onto the image is called a transformation.
What is transformation?
An operation that manipulates a polygon or other two-dimensional object on a plane or coordinate system is known as a transformation. Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
The two-dimensional shape without any transformations is known as a preimage or inverse image. The transformed figure is shown in the image.
In mathematics, there are five different transformations:
Dilation is the process of an image "shrinking" or "enlarging," depending on the size of the preimage.
Reflection: The picture is a preimage that has been reversed; "a flip."
Rotation: The picture is the preimage turned around a fixed axis; this is referred to as "a turn."
Shear: When a preimage is sheared, all the points along one side remain stationary while all the other preimage points move parallel to that side in proportion to the distance from the given side; this is also known as "a skew."
Translation: The image is "a slide" away from the preimage by a fixed amount.
The operation that maps(moves)the preimage onto the image is called a transformation.

How do you prove AAS congruence rule?
AAS (Angle-Angle-Side): If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of a second triangle, then the two triangles are congruent. Hence proved
AAS (Angle-Angle-Side):
Suppose we have two triangles from figure ABC and DEF, where,
∠B = ∠E [Corresponding angles] ∠C = ∠F [Corresponding angles] And
AC = DF [Adjacent sides]
By angle sum property of triangle, we know that;
∠A + ∠B + ∠C = 180 ………(1)
∠D + ∠E + ∠F = 180 ……….(2)
From equation 1 and 2 we can say;
∠A + ∠B + ∠C = ∠D + ∠E + ∠F
∠A + ∠E + ∠F = ∠D + ∠E + ∠F [Since, ∠B = ∠E and ∠C = ∠F] ∠A = ∠D
Hence, in triangle ABC and DEF,
∠A = ∠D
AC = DF
∠C = ∠F
Hence, by ASA congruency,
Δ ABC ≅ Δ DEF
So AAS (Angle-Angle-Side) congruence rule is hence proved.

The table shows the multiplication of two linear expressions. Select the correct reason for each step.
Reason 1:
Reason 2:
Reason 3:
here are the answer choices for the 3 reasons
(A)associative property of multiplication
(B)commutative property of multiplication
(C)istributive property
(D) simplify
Answer:
1. (C) Distributive property | 2. (A) Associative property | 3. (D) Simplify
Step-by-step explanation:
Here's my attempt:
Reason 1:
The first reason is (C) distributive property of multiplication because you're taking the previous step and spreading it out (distributing it). Here's an example of the distributive property of multiplication:
3(4+7) = 3*4+3*7=12+21=33
This will be the same as solving 3(4+7) using PEMDAS
In this step, you're spreading out the problem the same way as the example shown is doing.
Reason 2:
The second reason is (A) the associative property of multiplication. The associative property of multiplication says that changing the grouping of the numbers in a multiplication problem doesn't change the product.
Here's an example:
(6*7)*8 = 6*(7*8)
This way, the step groups together two pairs of factors to solve the last step without changing the product.
Reason 3:
The final reason is (D) Simplify because the step doesn't use the commutative property of multiplication. Why not? Because the commutative property of multiplication states that changing the order of factors in a multiplication problem doesn't change the product (note that this is different than the associative property of multiplication). Instead, the last step just simplifies the problem.
Hopefully, you read through my explanation, and it helped. Have a good day :D

Is f/x )= 3x² a function?
Answer:
yes.
Step-by-step explanation:
The definition of a function: "A function is defined as a relation between a set of inputs having one output each."
This means each x can only have 1 y value. You can check if this is a function using the vertical line test. To do the vertical line test draw vertical lines through the graph of the expression. If you even hit 2 points with a vertical line it is NOT as function.
The graph is of an upward facing parabola so it will be a function. We can graph and check this with the VLT which it passes.

f(0.5) = 4 [0.5] = 4 x 0 = 0
f(x) = 0 for 0 ≤ x < 1
f(1) = 4 [1] = 4
f(1.5) = 4 [1.5] = 4 x 1 = 4
f(x) = 4 for 1 ≤ x < 2
f(2) = 4 [2] = 4 x 2 = 8
f(2.5) = 4 [2.5] = 4 x 2 = 8
f(x) = 8 for 2 ≤ x < 2

What property of congruence is used for the statement AB ≅ AB?
The congruence's reflexive characteristic is applied to the statement AB ≅ AB.
In algebra, a number is always equal to itself according to the reflexive property of equality. The equality's reflexive quality. Assuming that an is a number, a = a. a=a. We discovered that anything is equal to itself thanks to the reflexive characteristic of equality. This characteristic's formula is a = a. All numbers are equal to one another, according to this property. For instance, three is three.
In mathematics, a set X's elements are considered to be reflexive if there is a relationship between each one of them. This can be expressed in terms of relations as (a, a) R a X or as I R, where I is the identity relation on A. As a result, it is said to hold reflexivity and to have a reflexive feature. Every angle, every line, and every figure or shape in geometry are congruent to one another according to the reflexive characteristic of congruence. This characteristic is typically employed in proofs of parallel lines and the congruence of two triangles.

a. y equals one fourth times x minus 16
b. y = 4x − 16
c. y equals one fourth times x plus 16
d. y = 4x 16
The equation that can be used to calculate how many minutes after 4:00 p.m. she will arrive at her location is y = 4x - 16.
The correct equation is:
y = 4x - 16
This equation represents the number of minutes after 4:00 p.m. the pilot will arrive at her destination. The variable x represents the time, in minutes, of her original flight, and y represents the number of minutes after 4:00 p.m. she will arrive at her destination. The expression "4x" represents the time the pilot will arrive at her destination if she had traveled at her original speed, and the "-16" represents the delay caused by air traffic.
To solve this equation, you would substitute the value of x into the equation and solve for y. For example, if the pilot's original flight time was 60 minutes, the equation would be:
y = 4(60) - 16
= 240 - 16
= 224

In mathematics, an ellipse is the location of points in a plane so that their separation from a fixed point has a fixed ratio of "e" to their separation from a fixed line (less than 1). The conic section, which is the intersection of a cone with a plane that does not intersect the base of the cone, includes the ellipse. The eccentricity of the ellipse is symbolized by the constant ratio "e," the fixed point is known as the focus, and the fixed line is known as the directrix (d).
Standard from of the equation of an ellipse with centre (0,0) and major axis on x-axis is,
x² / a² + y² / b² = 1
Standard from of the equation of an ellipse with centre (H, K) and major axis parallel to the x-axis is,
(x - h)² / a² + (y - k)² / b² = 1
