Answer:
The rule DO,0.25 (x, y) → (0.25x, 0.25y) is applied to the segment LM to make an image of segment L'M', not shown.
The coordinates of L' in the image are
✔ (–1, 2)
.
The coordinates of M' in the image are
✔ (1, 2)
.
The length, L'M', is
✔ 2
.
The slope of the original segment and dilated segment are
✔ both zero
.
Step-by-step explanation:
The question is incomplete. The complete question is:
On a coordinate plane, a line is drawn from point L to point M. Point L is at (negative 4, 8) and point M is at (4, 8). The rule DO,0.25 (x, y) → (0.25x, 0.25y) is applied to the segment LM to make an image of segment L'M', not shown. The coordinates of L' in the image are ??. The coordinates of M' in the image are ??. The length, L'M', is ??. The slope of the original segment and dilated segment are ??.
The coordinates of L' in the image are (-1, 2). The coordinates of M' in the image are (1, 2). The length, L'M', is 2. The slope of the original segment and dilated segment are both zero.
What is the dilation of a segment to its image?The dilation of a segment to its image is the following of a given rule for every point on the segment to create an image.
How do we solve the given question?We are given a line segment LM, with coordinates of L being (-4, 8) and that of M being (4, 8).
We are given a rule [tex]D_{O, 0.25} (x,y) \rightarrow (0.25x,0.25y)[/tex] which implies that every point on the line segment LM (x, y) is dilated to the point on the image L'M' as (0.25x, 0.25y).
The coordinates of L' in the image = (0.25*(-4), 0.25*8) = (-1, 2).
The coordinates of M' in the image = (0.25*(4), 0.25*8) = (1, 2).
The length of L'M' can be calculated using the distance formula between the points L' and M'.
Length = √((2 - 2)² + (1 - (-1))²) = √(0² + 2²) = √4 = 2 units.
∴ The length of L'M' = 2 units.
The slope of both LM and L'M' is 0, as they both are parallel to the x-axis and don't intersect with it.
∴ The coordinates of L' in the image are (-1, 2). The coordinates of M' in the image are (1, 2). The length, L'M', is 2. The slope of the original segment and dilated segment are both zero.

Answer:
-1/2
Step-by-step explanation:
3(y + 12) = 24
3y + 36 = 24
3y = 24 - 36
3y = -12
y = -12/3
y = -4

1/8 × (-4)
-4/8
-1/2
Answer:
-1/2
Step-by-step explanation:
3(y + 12) = 24
~Simplify left side
3y + 36 = 24
~Subtract 36 to both sides
3y = -12
~Divide 3 to both sides
y = -4
~Now substitute in 1/8y

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
On Friday= 26 pounds Apples sold.
On Saturday = 7 x 26= 182 pounds apples sold.
On Sunday = 32 pounds
Then, In three days total pounds of apples sold
= 26 + 182 + 32
= 240 pounds
Hence, in 3 days 240 pounds apples sold.

Can someone teach me all they know about Algebra Please (I really need this)
Answer:
Sureeeeeee
Step-by-step explanation:
Algebra (from Arabic: الجبر, romanized: al-jabr, lit. 'reunion of broken parts,[1] bonesetting[2]') is one of the broad areas of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols;[3] it is a unifying thread of almost all of mathematics.[4] It includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields. The more basic parts of algebra are called elementary algebra; the more abstract parts are called abstract algebra or modern algebra. Elementary algebra is generally considered to be essential for any study of mathematics, science, or engineering, as well as such applications as medicine and economics. Abstract algebra is a major area in advanced mathematics, studied primarily by professional mathematicians.
Elementary algebra differs from arithmetic in the use of abstractions, such as using letters to stand for numbers that are either unknown or allowed to take on many values.[5] For example, in {\displaystyle x+2=5}x+2=5 the letter {\displaystyle x}x is an unknown, but applying additive inverses can reveal its value: {\displaystyle x=3}x=3. Algebra gives methods for writing formulas and solving equations that are much clearer and easier than the older method of writing everything out in words.
The word algebra is also used in certain specialized ways. A special kind of mathematical object in abstract algebra is called an "algebra", and the word is used, for example, in the phrases linear algebra and algebraic topology.
A mathematician who does research in algebra is called an algebraist.
Numeric expressions apply operations to numbers. For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.
Answer:
<3.
Step-by-step explanation:
Algebra In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols. it is a unifying thread of almost all of mathematics. And algebraic expression includes, a variable is an x, but they could be different signs like maybe a y, q and etc. coefficient is the main number, an operation which is the sign (+, x, - or division sign). and then the constant, which are the last number and the final number.
I don't know how to explain it but as soon as you start to do it, you'll learn what algebra is! it's not that hard it's like doing a regular problem just with a variable.
Oh yeah, sorry if this out of order but sometimes in algebra you have to figure out what the x is in some problem. Khan academy could help you learn!
hope this helps <33.

5(1+2x)= 5 +10x =10x + 5
Answer:
Yes, they are eqivelant.
Step-by-step explanation:
5(1+2x) and 10x+5
The first step is to set them equal to each other, to see if they are equivelent.
5(1+2x) = 10x+5
Distribute the 5 to both terms in the parentheses by multiplying.
5(1) + 5(2x) = 10x +5
5 + 10x = 10x +5
The communative property of addition proves that these are equal.
