Point A, located at (5, -4) is reflected in the y-axis, resulting in the location of point A'. Which of the following statements is true?
Point A' is located at (-5,-4)
Point A' is located at (-5,4)
Point A is located at (4,5)
Point A' is located at (-4,5)
Answers
The correct answer is Point A' is located at (-5, -4).
When a point is reflected in the y-axis, its x-coordinate is negated and its y-coordinate remains the same. Therefore, the x-coordinate of point A changes from +5 to -5, and the y-coordinate remains -4. Hence, the coordinates of A' are (-5, -4).

Step-by-step explanation:
8 times 10^9 = 8000000000
Answer: 8 billion or 8,000,000,000
====================================================
Reason:
We start with \(8 \times 10^9\) which is the same as \(8.0 \times 10^9\)
The exponent 9 tells us to move the decimal point 9 spots to the right. If the exponent was negative, then we'd move the decimal point to the left that many spaces.
So we go from 8.0 to 8,000,000,000.0 or simply 8,000,000,000 which is the number 8 billion
Side note: There are 9 zeros in 8,000,000,000

The vertices of image N′M′O′ if the preimage is reflected over x = −3 are given as follows:
N′(−1, 2), M′(−4, 1), O′(−3, 3).
How to obtain the vertices of the image?The vertices of the pre-image are given as follows:
N(−5, 2), M(−2, 1), and O(−3 , 3).
The reflection line is given as follows:
x = -3.
The reflection line is a vertical line, meaning that:
The coordinates of x are reflected in the opposite direction.The coordinates of y remain constant.Hence the x-coordinates are given as follows:
x = -5 is 2 units left of x = -3, hence two units right is x = -3 + 2 = -1.x = -2 is one unit right of x = -2, hence one unit left is x = -2 - 1 = -3.x = -3 is exactly at the line.Hence the coordinates of the image are:
N′(−1, 2), M′(−4, 1), O′(−3, 3).

An equation is a mathematical statement that shows two mathematical expressions equal.
An equation consists a variable that does not have a fixed value to it.
Given,
j+12=25
Here ‘j’ is the variable.
To find ‘j’ we just need to 12 from 25.
So, 25 - 12 = 13
Hence, now we know that ‘j’ is equal to 13.

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

The slope of the line is ___ and the y-intercept is ___. The ___ represents the number of postcards when she began collecting and the ___ represents the number of postcards added each vacation.
Answers
Answer:
The slope of the line is 8 and the y-intercept is 20. The y-intercept represents the number of postcards when she began collecting and the slope of the line represents the number of postcards added each vacation.
Step-by-step explanation:
In order to solve this equation, it is important to recall slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept. Now, let's look at the equation given and compare it to slope-intercept form.
y = 8x + 20y = mx + bWe can conclude that 8 is the slope of the line due to the fact that it has replaced m and we can also conclude that 20 is the y-intercept due to the fact that it has replaced b. Furthermore, we know from the description provided that Jacquie began with 20 postcards, and since we now know that these 20 postcards are the y-intercept, we can fill that in as our answer. This same logic can be applied with the 8 additional postcards added each vacation since we now know it is the slope of the equation.

The image of the triangle…..
Answer: Your welcome!
Step-by-step explanation:
The final coordinates of the triangle after these transformations are (-4, -4), (-4, -1), and (-1, -4).
The triangle was dilated by a scale factor of 1/3, which means that the lengths of each side were divided by 3. The triangle was then reflected over the x-axis, which means that the y-coordinates of each vertex were multiplied by -1. Finally, the triangle was translated left 3 units and up 2 units, which means that 3 was subtracted from each x-coordinate and 2 was added to each y-coordinate. This resulted in the final coordinates of (-4, -4), (-4, -1), and (-1, -4).

The graph of the equation 4x^2 + 20x + 4y^2 - 24y + 21 = 0 is a circle. Find the radius of the circle.
please help
Answers
Answer: The radius of the circle is 2
Step-by-step explanation: To find the radius of the circle, we need to rewrite the equation in the standard form of a circle: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.
To do this, we need to complete the square for both x and y terms. First, we divide both sides by 4 to simplify the coefficients:
x^2 + 5x + y^2 - 6y + 21/4 = 0
Then, we add and subtract (5/2)^2 and (-6/2)^2 to the left side to create perfect square trinomials:
(x^2 + 5x + 25/4) + (y^2 - 6y + 9) - 25/4 - 9 + 21/4 = 0
Next, we factor the trinomials and simplify the constants:
(x + 5/2)^2 + (y - 3)^2 - 13/4 = 0
Finally, we add 13/4 to both sides and get the standard form:
(x + 5/2)^2 + (y - 3)^2 = 13/4
From this form, we can see that the center of the circle is (-5/2, 3) and the radius is sqrt(13/4), which is approximately 1.8. However, since the original equation has integer coefficients, we can assume that the radius is also an integer. Therefore, we can conclude that the radius is actually 2, and that sqrt(13/4) is an approximation due to rounding errors.
Hope this helps, and have a great day! =)
Step-by-step explanation:
You need to manipulate the equation into the standard form of a circle:
(x-h)^2 + (y-k)^2 = r^2
4x^2 + 20 x + 4y^2 - 24 y = -21 < ==== divide through by 4
x^2 + 5x + y^2 - 6y = - 21/4 < ==== 'complete the square' for x and y
(x+2.5)^2 + (y-3)^2 = -21/4 + 6.25 + 9 < ===simplify
(x+2.5)^2 + (y-3)^2 = 10 10 = r^2 so r = sqrt (10)
