The composition do,0.75(x,y) ∘ do,2(x,y) is applied to △lmn to create △l''m''n''. which statements must be true regarding the two triangles? check all that apply. ∠m ≅ ∠m'' △lmn ~ △l''m''n'' △lmn ≅ △l''m''n'' the coordinates of vertex l'' are (-3, 1.5). the coordinates of vertex n'' are (3, -1.5). the coordinates of vertex m'' are (1.5, -1.5).
Answer:
A. ∠M ≅ ∠M''
B. △LMN ~ △L''M''N''
E. The coordinates of vertex N'' are (3, -1.5).
Step-by-step explanation:
Transformation involves changing the position and size of a shape.
The true statements are:
[tex]\mathbf{\angle m \cong \angle m"}[/tex].[tex]\mathbf{\triangle lmn \sim \triangle l"m"n"}[/tex].The coordinates of n" are [tex]\mathbf{N" = (3,-1.5)}[/tex].The coordinates of the triangle are:
[tex]\mathbf{L = (-1, 2)}[/tex]
[tex]\mathbf{ M = (-1, -1)}[/tex]
[tex]\mathbf{N = (2, -1)}[/tex]
The transformation rule is given as:
[tex]\mathbf{do, 0.75(x,y)\circ,2(x,y)}[/tex]
The transformation rule is a dilation by a factor of 0.75, and then a factor of 2.
Uniform dilation changes the size of a shape, but the angles remain unchanged. This means that:
[tex]\mathbf{\angle l \cong \angle l"}[/tex].[tex]\mathbf{\angle m \cong \angle m"}[/tex].[tex]\mathbf{\angle n \cong \angle n"}[/tex].[tex]\mathbf{\triangle lmn \sim \triangle l"m"n"}[/tex]The above highlights means that:
The angles of both triangles are congruentThe triangles are similarNext, we apply the rule on the coordinates of the triangle
[tex]\mathbf{L" = 0.75 \times 2 \times (-1,2)}[/tex]
[tex]\mathbf{L" = (-1.5,3)}[/tex]
[tex]\mathbf{M" = 0.75 \times 2 \times (-1,-1)}[/tex]
[tex]\mathbf{M" = (-1.5,-1.5)}[/tex]
[tex]\mathbf{N" = 0.75 \times 2 \times (2,-1)}[/tex]
[tex]\mathbf{N" = (3,-1.5)}[/tex]
Hence, the true statements are:
[tex]\mathbf{\angle m \cong \angle m"}[/tex].[tex]\mathbf{\triangle lmn \sim \triangle l"m"n"}[/tex].The coordinates of n" are [tex]\mathbf{N" = (3,-1.5)}[/tex].Read more about transformations at:

Answer:
A segment whose length is 9 units.
Step-by-step explanation:
A segment whose length is 9 units.
All we have is a bisection that divides equally segment JK in two parts. And M is the Midpoint what reassures us that JM=MK, so plugging in:

A quadrilateral is shown on the graph:
What effect will a reflection about the x-axis have on the quadrilateral? Be sure to address how it could impact the angles, side lengths, and congruency between the original pre-image and the image.
Answer:
The angles and side length would remain the same, the only thing that would change is the cornents, therefore the original pre image and the image would be congruent.
Step-by-step explanation:
Solve for x.

Suppose that a number written as a decimal has an infinite number of non–repeating digits after the decimal point. what is this number called?
When a number has an infinite number of non-repeating digits, which is called a non-terminating decimal value, then such number is an irrational number such as 1.3127...
Irrational number are real numbers which cannot be expressed in the form of p/q ; that is they cannot be expressed accurately as a ratio.They are characterized as having repeating decimal values as well as non-terminating decimal digits. When a number has unending or infinite number of non-repeating digits, it is said to be non-terminating, hence, such number is called an irrational number.

Suppose you had d dollars in your bank account. You spent $22 but have at least $28 left. How much money did you have initially? Write and solve an inequality that represents this situation.
A) d + 22 ≤ 28; d ≤ 72
B) d – 22 > 28; d > 50
C) d + 22 ≥ 28; d ≥ 72
D) d – 22 ≥ 28;d ≥ 50
Answer:
D) d – 22 ≥ 28;d ≥ 50
Step-by-step explanation:
Let d represents the initial money ( in dollars ) in the account,
So, after spending $ 22 the remaining amount = initial amount - $ 22 = (d-22) dollars,
According to the question,
The remaining amount ≥ $ 28
⇒ d - 22 ≥ 28
Adding 22 on both sides, ( additive property of inequality ),
⇒ d ≥ 50
Hence, the required inequality and its solution would be,
d - 22 ≥ 28; d ≥ 50
Option 'D' is correct.
What affect does "h" have on the parent function y = 1/x ?
h < 0 moves the graph to the left, h > 0 moves the graph to the right.
Vertical stretch by a factor of |h|
h > 0 moves the graph up, h < 0 moves the graph down.
h > 0 reflects the graph across the y-axis.

How many three quarter pound burgers can be made with twelve pounds of hamburger?
Answer:
[tex]16\ burgers[/tex]
Step-by-step explanation:
Let
n ----> the number of burgers
x ----> the total pounds of hamburger
we know that
To find out the number of burgers, divide the total pounds of hamburger by three quarter pound (3/4 lb)
we have
[tex]x=12\ lb[/tex]
so
[tex]n=\frac{12}{(3/4)}=\frac{48}{3}=16\ burgers[/tex]
This results in 16 burgers. To find out how many three quarter pound burgers can be made with twelve pounds of hamburger, you divide the total pounds of hamburger by 0.75.
First, you need to perform a division calculation.
Note that a three quarter pound burger is equivalent to 0.75 pounds.
Determine how many three quarter pound burgers equal twelve pounds by dividing the total pounds of hamburger by the weight of one burger:12 pounds ÷ 0.75 pounds per burger = 16 burgers.Therefore, you can make 16 three quarter pound burgers with twelve pounds of hamburger.
