The coordinates of the image of ABCD after applying the given transformation are, A"(2, 0), B"(0, -4), C"(-4, -6), and D"(-2, -2).
What is transformation of points?
The reflection is the kind of transformation that takes place whenever a shape's points cross a line. When the points are reflected over a line, the image is on the opposite side of the line from the pre-image and is located at the same distance from the line. The image point is reflected from each point (p, q).
Given:
Quadrilateral ABCD has coordinates A(−2, 0), B(0, 4), C(4, 6), and D(2, 2).
First to find the coordinates after applying the transformation
(x, y) ⟶ (–x, y).
So,
A(-2, 0) ⟶ A'(2, 0)
B(0, 4) ⟶ B'(0, 4)
C(4, 6) ⟶ C'(-4, 6)
D(2, 2) ⟶ D'(-2, 2)
Now applying the transformation (x, y) ⟶ (x, –y)
A'(2, 0) ⟶ A"(2, 0)
B'(0, 4) ⟶ B"(0, -4)
C'(-4, 6) ⟶ C"(-4, -6)
D'(-2, 2) ⟶ D"(-2, -2)
Hence, the coordinates of the image of ABCD after applying the given transformation are, A"(2, 0), B"(0, -4), C"(-4, -6), and D"(-2, -2).

Use the figure at the right to identify the angle pair relationship.
Angles ∠1 and ∠7 are alternate interior angles and angle ∠4 and ∠8 are adjacent angles.
What are lines and angles?Lines are straight with little depth or width. Perpendicular lines, intersecting lines, transversal lines, and other types of lines will be covered. An angle is a shape formed by two rays emerging from a common point. In this field, you may also come across alternate and equivalent angles.
The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
When a transversal connects two coplanar lines, alternate interior angles are generated. They are on the inside of the parallel lines, but on the outside of the transversal.

What is the slope of the line through the points x1 y1 and x2 y2?
The slope of a line through the two points is (y2-y1) / (x2 - x1).
The slope of a line:
The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).
Here we have to find the slope of the line.
Data given:
Point one has the coordinate = (x1, y1)
Point two has the coordinate = (x2, y2)
So the slope of the line(m) =( y2 - y1) / (x2 - x1)
Therefore the slope of the line is (y2- y1) / ) (x2-x1)

In the given expansion ,the value of a = -4/3 .
Binomial Distribution:
The binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a series of n independent experiments. Each asks a yes-no question and each has its own Boolean outcome: success (probability p) or failure (probability p) (probability q = 1-p. A single success/failure experiment is also called a Bernoulli trial or Bernoulli experiment, and a series of results is called a Bernoulli process. For one trial, n = 1, binomial distribution is Bernoulli distribution. The binomial distribution is the basis for the common binomial test of statistical significance.
In general, (A + B)⁵ = A⁵ + 5A⁴ᵇ + 10A²ᵇ*³ + 10A³ᵇ*² + 5AB⁴ + B⁵
So,

Multiplying that by (1 + ax) gives:
3^5 + 5*3^4*(-2x) + 10* 3^3 *(-2x)^2 + 10*3^2*(-2x)^3 + 5*3*(-2x)^4 + (-2x)^5 + ax(3^5 + 5*3^4*(-2x) + 10* 3^3 *(-2x)^2 + 10*3^2*(-2x)^3 + 5*3*(-2x)^4 + (-2x)^5).

a certain spinner is divided into 6 sectors of equal size, and the spinner is equally likely to land in any sector. four of the 6 sectors are shaded, and the remaining sectors are not shaded.
The probability that one spin of the spinner will land in a shaded sector is 2/3.
What is meant by probability?The likelihood that something will happen is the straightforward definition of probability. When we are unsure of how an event will turn out, we might talk about the probabilities of various outcomes or how likely they are. The study of events subject to probability is referred to as statistics.
Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or of a proposition being true.
When the spinner is released, there is a low likelihood that the part will rest on four.
Information: A particular spinner has equal-sized sectors, and it is equally likely to land in any of them. The remaining sectors are not coloured, and four of the sectors are shaded.
Four of the sectors are shaded, while the remaining sectors are not, according to the enigma.
The spinner has two unshaded areas and four shaded areas.

Answer:
y = 1/5x -5
Step-by-step explanation:
Slope intercept form is y=mx + b where m is the slope and bb is the intercept. Let's find the slope first. This is rise over run, so we take the difference of two points' y-coordinates and divide it by the x-coordinates' difference.
This gives us [tex](-4--6)/(5--5)[/tex], or [tex]2/10[/tex], which simplifies to [tex]1/5[/tex]. This is our slope. Now we have y = 1/5x + b. We now plug in a point to this equation to get b. Plugging in (-25, -10) gives us [tex]-10 = 1/5*-25 + b[/tex], or [tex]-10 = -5 + b[/tex]. From this we get that b = -5. So, our equation is y = 1/5x -5

Amount of caffeine in green tea = 12 × 6.25
Amount of caffeine in green tea = 75 mg
Total caffeine in the mixture = 1368 + 75
Total caffeine in the mixture = 1443 mg
Total amount of mixture = 12 + 24
Total amount of mixture = 36

ten less the the quotient of a number and 3 is 8
x/3-10=8
Add 10 to each side x/3=18 Multiply by 3
Answer:
x/3 - 10 = 8
Step-by-step explanation:
It seems like you want me to provide an equation, so here it is:
10 less equates to "minus 10", or "10 minus". [-10]
Quotient refers to division, and "a number" can be replaced with a variable: x. This is our numerator. Our denominator is "3", as it states, "and 3". Finally, the "is" statement refers to equality, and we can replace this with the equal sign.
Putting these all together, you get the equation, x/3 - 10 = 8.

the statement says that you’ve triggered the penalty apr so that it has now increased to 28.99%. what action triggered this?
If you failed to pay the minimum payment by the due date and are now being charged the penalty APR of 28.99%, your monthly interest charge on a balance of $1800 would be approximately $518.82. This is calculated as follows:
$1800 * (28.99% / 12 months) = $518.82However, it is important to note that this calculation is an estimate and the actual amount of interest you would owe in one month could be different, depending on factors such as the number of days in the billing period and the daily interest rate. It is also worth noting that you were charged $6.31 in interest for purchases, which is separate from the interest charged on your unpaid balance.

The answer can't be a decimal number, because you can't split up cards into quarters like chocolate or bars.
METHOD 1:
Use long division to solve; 4 fits 4 times into 16, and 5 fits 4 times into 1; thus you get 41.

Write the equation of the following lines in slope-intercept form
Answer:
Green Graph: y = x - 6
Red Graph: y = -3/2 + 7
Step-by-step explanation:
Slope intercept form is represented by the formula:
y = mx + b
m is your slope
b is the y intercept
Another thing to note is that, when m is negative, the graph will point to the left, while when m is positive in will point in the right
For the green graph, the line intercepts at -6, so that will be your b value.
the slope is positive 1 because if your count up from -6 and count across to point (1,-5) you get 1/1
Put these pieces of information in your formula and you get
y = x - 6
You can use the same process to find the equation of the red line. However, the slope will be negative since the graph is pointing to the left side of the coordinate plane.
Answer:
Graph 1: y = x - 6
Graph 2: y = -3/2 + 7
