The midpoint of AB is M (5,-2). If the coordinates of A are (6,-5), what are the
coordinates of B?
Answer:
(4, 1)
Step-by-step explanation:
To find the second point, first, we must look at how far apart the midpoint and point A are from each other
As seen in picrel, the midpoint is 3 units up and 1 unit left from point A.
We will repeat these units diagonally to make a linear line to find the next point.
3 units up and 1 unit left from the midpoint is (4, 1) which is point B.
For future problems related to finding the second point with only the midpoint and the first point, refer to step 1.

identify the population being studied and the sample chosen. the heights of 4 out of the 36 pepper plants at mr. lonardo's greenhouse.
The sample = 4 pepper plants
The population = 36 pepper plants
We have to identify the sample and the population from the instance that heights of 4 out of 36 pepper plants are chosen.
Statistical studies are carried out on populations. So here there may be a study related to the heights of the pepper plants.
Sometimes, when the population is very large, studies are carried out on the samples taken from the population which gives not the exact but an approximately same result.
Hence in this case, the sample is the 4 plants chosen from the population of 36 plants at Mr. Lonardo's greenhouse.
Population: Population is the entire and broader group considered for collecting data on a statistical study.
Sample: Sample is the specific, comparatively small group selected from the population from which the data used for study is collected.

New Year’s Eve is a public holiday in places such as Latvia, the Philippines, and San Marino. It is a holiday for banks in countries such as Bangladesh, Brunei, Paraguay, and Japan (New Year’s Eve is also a government holiday in Japan).
New Year’s Eve is not a nationwide public holiday in countries such as Australia, Canada, the United Kingdom and the United States, but some businesses close early, schools are usually closed, and many people may have half a day off work. Those wishing to travel via public transport may need to check with the local transport authorities on public transport schedules for New Year’s Eve.
Background
New Year's Eve is the last day of the year and the day before New Year’s Day, which marks the start of a new year according to the Gregorian calendar. Pope Gregory XIII introduced the Gregorian calendar in 1582. It was adopted immediately in some areas of Europe but it was not used in various countries until even centuries later. For example, the United Kingdom and the United States started observing the Gregorian calendar in 1752, in which 11 days were dropped.
New Year’s Eve festivities can be traced back to celebrations in Europe that date back before Christianity spread. When many inhabitants in Europe were converted to Christianity, these festivals were merged with Christian beliefs and in time came to mark holidays such as the New Year’s Eve and New Year celebrations.
It is important to note that not all cultures follow the Gregorian calendar in observing New Year’s Eve and New Year’s Day. For example the New Year in the Hindu, Chinese, Coptic, Jewish, Islamic calendars differ to that of the Gregorian calendar.
Symbols
New Year’s Eve and New Year’s Day are symbolized in various ways across the world. Midnight between New Year’s Eve and New Year’s Day is often marked by fireworks and fire crackers. Many people drink and toast with champagne or other sparkling wine.

Last year, the school library had a total of x books. Over the summer, the library acquired another 40 books and now has a total of 1,795 books. Which equation could be used to find x, the number of books the library had last year?
Answer:
1794-40=x?
Step-by-step explanation:
this is genuine answer but a little bit unsure
Last year = x books
This year = x + 40 books
The needed equation is x + 40 = 1,795.

The perimeter of a rectangle is 56 cm. When its length is reduced by 2 cm and its
width is increased by 4 cm, a square is formed. What is the area of the rectangle ?
A rectangle has vertices E(-4, 8), F(2, 8), G(2, -2) and H(-4, -2). The rectangle is dilated with the origin as the center of dilation so that G' is located at (5, -5). Which algebraic representation represents this dilation?
Answer:
The dilation on any point of the rectangle is [tex]P'(x,y) = \frac{5}{2}\cdot P(x,y)[/tex].
Step-by-step explanation:
From Linear Algebra, we define the dilation of a point by means of the following definition:
[tex]G'(x,y) = O(x,y) +k\cdot [G(x,y)-O(x,y)][/tex] (1)
Where:
[tex]G(x,y)[/tex] - Coordinates of the point G, dimensionless.
[tex]O(x,y)[/tex] - Center of dilation, dimensionless.
[tex]k[/tex] - Scale factor, dimensionless.
[tex]G'(x,y)[/tex] - Coordinates of the point G', dimensionless.
If we know that [tex]O(x,y) = (0,0)[/tex], [tex]G(x,y) =(2,-2)[/tex] and [tex]G'(x,y) =(5,-5)[/tex], then scale factor is:
[tex](5,-5) = (0,0) +k\cdot [(2,-2)-(0,0)][/tex]
[tex](5,-5) = (2\cdot k, -2\cdot k)[/tex]
[tex]k = \frac{5}{2}[/tex]
The dilation on any point of the rectangle is:
[tex]P'(x,y) = (0,0) + \frac{5}{2}\cdot [P(x,y)-(0,0)][/tex]
[tex]P'(x,y) = \frac{5}{2}\cdot P(x,y)[/tex] (2)
The dilation on any point of the rectangle is [tex]P'(x,y) = \frac{5}{2}\cdot P(x,y)[/tex].
Algebraic representation of the dilation will be T'(x, y) → T(2.5x, 2.5y).
Dilation of a rectangle about a point not the origin:Let one of the four vertices of a rectangle is (h, k) is dilated about the origin by the scale factor 'k'.Rule for the transformation will be,
[tex]D_{(o,k)}(x,y)\rightarrow (kx,ky)[/tex]
Following this rule,
If one of the vertices of a rectangle is G(2, -2) and it is dilated by a scale factor 'k', image point will be given by,[tex]D_{(o,k)}(2, -2)\rightarrow (2k, -2k)[/tex]
Since, coordinates of the dilated point are G'(5, -5),
Therefore, (2k, -2k) = (5, -5)
⇒ 2k = 5
⇒ k = 2.5
Hence, algebraic representation defining the dilation of the
triangle will be,
T'(x, y) → T(2.5x, 2.5y)
Algebraic representation of the dilation will be T'(x, y) → T(2.5x, 2.5y).

What is the solution to this inequality?
7x + 25<=11
Answer:
Step-by-step explanation:
smplifying
7x + 11 = 25
Reorder the terms:
11 + 7x = 25
Solving
11 + 7x = 25
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-11' to each side of the equation.
11 + -11 + 7x = 25 + -11
Combine like terms: 11 + -11 = 0
0 + 7x = 25 + -11
7x = 25 + -11
Combine like terms: 25 + -11 = 14
7x = 14

Write a two-column proof

Prove: m∠2 = 45°
Notice:
Unfortunately I’ve never written a two-column proof before. So I can’t do that. Let me know if what I can do helps at all though.
Step-by-step explanation:
A supplementary angle is an angle made up of two angles that have measures that add up to 180°. m∠2 = 45° because 45° added to 135° equals 180°. Therefore making it a supplementary angle. Meaning that m∠2 = 45° is true. Sorry if this doesn’t help. I tried my best.

How to write vertex form when given to choices of “a” in a question ex: write the vertex form of the function where a=1 or a= -1 and H and K are integers? And the vertex is (-1,4)
Answer:
Step-by-step explanation:
Vertex form of quadratic equation is
[tex]y = a(x-h)^2 + k[/tex]
where h and k are the x and y coordinates of the vertex, respectively.
so in this problem
if a=1 and Vertex is (-1,4) means h= -1 and k = 4
the equation will be
[tex]y = 1 (x-(-1))^{2} + 4[/tex]
[tex]y = (x+1)^2 + 4[/tex]
if a=-1 and Vertex is (-1,4) means h= -1 and k = 4
the equation will be
[tex]y = -1 (x-(-1))^{2} + 4[/tex]
[tex]y = -(x+1)^2 + 4[/tex]

angle C and angle D are a linear pair. angle C is four times larger than angle D. What is the measure of angle C?
By using the fact that the angles form a linear pair, we will see that the measure of angle C is 144 degrees.
How to determine the measures of angles C and D?
Well, we know that these are a linear pair, which means that the angles are supplementary, thus, their measures add up to 180°.
So we can write:
C + D = 180°
Now, we also know that C is four times larger than D, so we can write:
C = 4*D
Replacing that in the equation above we get:
4*D + D = 180°
5*D = 180°
D = 180°/5 = 36°
Then we know that the value of D is 36°, and C is 4 times that, so:
C = 4*36° = 144°
The measure of angle C is 144 degrees.

If f(x) = 3x + 4(x + 1) + 2 then f (4x) =?
Answer:
3×+4(×+2 then f (4×)=21
The expression for f(4x) is 28x + 6. When you evaluate the function f at 4x, you obtain 28 times x + 6. For every value of x, you can plug it into the equation 28x + 6 to get f(4x).
To find the expression for f(4x), we substitute 4x for every occurrence of x in the original function f(x).
Given f(x) = 3x + 4(x + 1) + 2, we have to replace every x with 4x:
f(4x) = 3(4x) + 4(4x + 1) + 2
Now, simplify the expression:
f(4x) = 12x + 4(4x + 1) + 2
f(4x) = 12x + 16x + 4 + 2
f(4x) = 28x + 6
Therefore, the expression for f(4x) is 28x + 6.
This means that when you evaluate the function f at 4x, you get 28 times the value of x plus 6. So, for any given value of x, you can plug it into the expression 28x + 6 to get the corresponding value of f(4x).
