I will give the Brainliest answer! PLEASE HELP! The vertices of a triangle are located at the points A (1,1) , B (2,3), C (5,0). The triangle is translated 4 units down, then reflected across the x-axis to obtain triangle A'B'C'. What are the coordinates of the vertices of triangle A'B'C'?
To find the coordinates of the vertices A'B'C' of the new triangle after translation and reflection, subtract 4 from the y-coordinate of each vertex and change the sign of the y-coordinate.
Explanation:To find the coordinates of the vertices A'B'C' of the new triangle, we first translate the original triangle 4 units down. This means we subtract 4 from the y-coordinate of each vertex. So, the new coordinates of A', B', and C' are: A' (1, -3), B' (2, -1), and C' (5, -4).
Next, we reflect the translated triangle across the x-axis. To do this, we change the sign of the y-coordinate of each vertex. So, the final coordinates of A'B'C' are: A' (-1, 3), B' (-2, 1), and C' (-5, 4).

Cassandra is trying to think of a good way to keep her financial records. She makes a lot of purchases, using cash, debit cards, and credit cards about equally. When she gets home every day, she tends to be very tired and doesn’t like to do a lot of organized thinking. She tends to lose individual pieces of paper if she doesn’t file them immediately. What might be a good method for Cassandra to use? a. Recording all of her daily expenditures in an organizational computer program. b. Keeping and collecting receipts for everything she buys. c. Tracking and collecting her bank and credit statements every month. d. Carrying a notebook and immediately recording all of her transactions in it.
Answer:
d. Carrying a notebook and immediately recording all of her transactions in it.
Step-by-step explanation:
The correct answer is option D.
What is bank statement?A bank statement is a document that is typically sent by the bank to the account holder every month, summarizing all the transactions of an account during the month.
Bank statements contain bank account information, such as account number and a detailed list of deposits and withdrawals.
Cassandra's best option would probably be carrying a notebook and immediately recording all of her transactions in it.
Since she does not like to do a lot of heavy thinking when she gets home, and tends to lose pieces of paper, this method is ideal because it would allow her to consolidate all her purchase records in one notebook, eliminating the need to carry receipts, and recording them immediately will make it so she can relax when she gets home.
Perhaps once a month, she can compile all of her notebook activity into a computer program and reconcile it to her bank statements.
Hence, the correct option is D.

How do you know when the function is in simplified form?
Final answer:
A function is in simplified form when all unnecessary terms have been eliminated, subscripts are used appropriately, and it uses the most compact and standard notation possible. Always verify the reasonableness of the simplified function.
Explanation:
To determine when a function is in simplified form, several steps should be followed:
Eliminate terms wherever possible to simplify the algebra.Use the simplified subscript in the final formula.Do not write the subscript if it is one, as it is understood to be implied.Condense constant quantities within parentheses, replacing them with a single symbol, for example, 'a', to make the equation look simpler.When an equation contains more than one unknown, use an additional equation to solve the problem.In cases where several unknowns must be determined, keep physical principles in mind and possibly use multiple equations to find the required variable.Condense formulas for chemical structures by using subscripts to denote multiple identical elements, making notation more compact.When you have eliminated all unnecessary terms and used standard conventions for simplification mentioned above, the function is considered to be in its simplest form. It is always good practice to check the answer to see if it is reasonable and does not violate any known principles or constraints.

The consecutive integers are 5 and 6.
What are integers?Any positive or negative number without fractions or decimal places is known as an integer, often known as a "round number" or "whole number."
Given:
The sum of the reciprocals of two consecutive integers is 11/30.
Let the integers be n and n+1.
Then,
1/n + 1/n+1 = 11/30
{n + 1 + n}/n(n+ 1) = 11/30
30(2n+1 ) = 11(n²+n)
60n + 30 = 11n² + 11n
11n² - 49n - 30 = 0
(11n +6) (n-5) = 0
Only taking,
n = 5.
So, 5 and 6.
Therefore, 5 and 6 are the integers.

Which statement is true the graph of y=log(x-4) is the graph of y=log(x) translated 4 units down
The true statement is: The graph of [tex]\(y = \log(x) + 4\)[/tex] is the graph of y = (log(x) translated 4 units up.
Let's analyze each statement:
1. The graph of [tex]\(y - \log(x-4)\)[/tex] is the graph of [tex]\(y - \log(x)\)[/tex] translated 4 units down.
This statement is incorrect. The function [tex]\(y - \log(x-4)\)[/tex] is the result of shifting the graph of [tex]\(y = \log(x)\) 4[/tex] units to the right, not down.
2. The graph of [tex]\(y = \log(x) - 4\)[/tex] is the graph of [tex]\(y = \log(x)\)[/tex] translated 4 units down.
This statement is incorrect. The function [tex]\(y = \log(x) - 4\)[/tex] represents a vertical translation of 4 units down from the graph of [tex]\(y = \log(x)\)[/tex], not left.
3. The graph of [tex]\(y = \log(x) + 4\)[/tex] is the graph of [tex]\(y = \log(x)\)[/tex] translated 4 units up.
This statement is true. Adding a constant term to a function vertically shifts the graph of the function by that amount. So, adding 4 to [tex]\(y = \log(x)\)[/tex] shifts it 4 units up.
4. The graph of [tex]\(y = \log(x+4)\)[/tex] is the graph of [tex]\(y = \log_2(x)\)[/tex] translated 4 units right.
This statement is incorrect. The function [tex]\(y = \log(x+4)\)[/tex] represents a horizontal translation of 4 units to the left from the graph of [tex]\(y = \log(x)\).[/tex]
Therefore, the true statement is: The graph of [tex]\(y = \log(x) + 4\)[/tex] is the graph of y = (log(x) translated 4 units up.
Question
Which statement is true?
The graph of Y - log(x-4) is the graph of y-log,(x) translated 4 units down.
The graph of Y = log: (x)-4 is the graph of y = log. (x) translated 4 units left.
The graph of y = log,(x)+4 is the graph of Y=log.(x) translated 4 units up.
The graph of y = log. (x+4) is the graph of y = log2 (x) translated 4 units right.

A triangle has side lengths 24, 32, and 42. is it a right triangle? explain.
Answer:
triangle given is not a right triangle
Step-by-step explanation:
Given:-
- The side lengths of a triangle are given as:
24 , 32 , 42
Find:-
is it a right triangle? explain
Solution:-
- Any triangle which conforms to the pythagorean theorem can be classified as a right angle triangle.
- The Pythagorean theorem states that the square of the longest side length known as hypotenuse (H) should be equal to the sum of square of other two side lengths ( Perpendicular / opposite [ P ] and Base / Adjacent [ B] ).
- This can be mathematically expressed as:
H^2 = P^2 + B^2
- From the given side lengths. The largest side length is hypotenuse H = 42. While P and B can be used interchangeably for the other two side lengths. So using the theorem we have:
42^2 = 32^2 + 24^2
1764 : 1024 + 576
1764 ≠ 1600
- We see that the three side lengths of the triangle does not conform to theorem. So we can conclude that the triangle given is not a right triangle.
Since 1764 is not equal to 1600, the triangle is not a right triangle.
To determine if the triangle is a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Let's denote the sides as follows:
a = 24, b = 32, c = 42
Using the Pythagorean theorem:
c² = a² + b²
Plugging in the values:
42² = 24² + 32²
1764 = 576 + 1024
1764 = 1600

Answer:
2.[tex]16a^2-4a+4a-1[/tex]
Step-by-step explanation:
We have to find the polynomial can be simplified to a difference of squares.
1.[tex]10a^2+3a-3a-16[/tex]
Combine like terms
[tex]10a^2-16[/tex]
10 in [tex]10a^2[/tex] is not a perfect square number because when a number end with one zero then the number is not perfect square number.
Therefore, it can not be simplified to a difference of squares.
2.[tex]16a^2-4a+4a-1[/tex]
[tex]16a^2-1[/tex]
Combine like terms
[tex](4a)^2-(1)^2[/tex]
Hence, the polynomial can be simplified as difference of squares.
3.[tex]25a^2+6a-6a+36[/tex]
Combine like terms
[tex]25a^2+36[/tex]
[tex](5a)^2+(6)^2[/tex]
Hence, the polynomial can not be simplified as difference of squares because the polynomial can be simplified as sum of squares.
4.[tex]24a^2-9a+9a+4[/tex]
Combine like terms
[tex]24a^2+4[/tex]
[tex]24a^2+(2)^2[/tex]
[tex]24=2\times 2\times 3\times 2[/tex]
24 is not a perfect square number because when factorize 24 then 2 and 3 are not paired.
Hence, the polynomial can not be simplified as difference of squares.
