For each graph, describe the composition of transformations that maps ADEF
to ALMN.
Answers
Answer:
From the figure, it can be seen that ΔJ'K'L' is formed from ΔJKL by the rotation of ΔJKL by 90 degrees counter-clockwise.
It can also be seen that ΔJ"K"L" is obtained from ΔJ'K'L' by the refrection of ΔJ'K'L' across the x-axis.
Therefore, the rule that describes the composition of transformations that maps ΔJKL to ΔJ"K"L" is given by

What is her score for the game?
A 16.25

Answer: B. 13.75
First write out the equation you need to solve
1x - 0.25y = total score
Second fill in the known information
1(15) - 0.25(5) = total score
Now solve your equation
15 - 1.25 = total score
13.75 = total score
Her score for the game will be 13.75. Then the correct option is B.

Your class collected money to buy turkeys and hams for
the local food shelter. After the collection, your class
had exactly enough money to buy 11 hams and 9
turkeys. If you raised a total of $316, and each turkey
cost $18, how much is one ham?
Answers
Answer: $14.00
Step-by-step explanation:
9 turkeys costed a total amount of $162.00
We need to subtract that from the total cost, $316.00, to find out how much money was spent on 11 hams.
316 - 162 = 154
So, 11 hams costed 154.
We then need to find the unit rate of 11 turkeys for 154 dollars.
To do that, we must divide 154 ÷ 11
That gives us 14.
Therefore, your answer is: $14.00 per ham.

y = -x +3y = x -3y = 3x +1y = -3x -3Step-by-step explanation:
In each case, the slope can be found by counting the number of vertical grid squares for each horizontal grid square between points where the line crosses grid intersections. The ratio "rise"/"run" is the slope of the line, m.
The y-intercept, b, can be found as the y-value where the line crosses the y-axis.
These values go into the slope-intercept form of the equation for a line to give the equation you want:
y = mx + b
__
1. Rise is -1 for a run of 1. The y-axis is crossed at 3.
y = -x +3
__
2. Rise is 1 for a run of 1. The y-axis is crossed at -3.
y = x -3
__
3. Rise is 3 for a run of 1. The y-axis is crossed at 1.
y = 3x +1
__
4. Rise is -3 for a run of 1. The y-axis is crossed at -3.

Answers
Answer:
5/6.
Step-by-step explanation:
The only composite numbers on a die are 4 and 6, so the probability of landing on them is 2/6 or 1/3. The probability of landing on tails on a coin is 1/2. Add them together (1/3 + 1/2) and you get the total probability of 5/6.

slope of y = 7x-100
Answers
Answer:
The slope equals 7.
Step-by-step explanation:
Following the formula y = mx + b where:
m = slope
x = independent variable
b = y-intercept
our equation looks like:
y= 7x - 100
m = 7
x = x
b = -100
If slope = m and m = 7 then we can conclude that the slope = 7.

A. No; a reflection changes the orientation of a figure, so the figures are not congruent.
B. No; a translation changes the position of a figure, so the figures are not congruent.
C. Yes; reflections and translations preserve lengths and angle measures, so the figures are congruent.
D. There is not enough information.
Answers
Answer:C
Step-by-step explanation: Measure stay the same when translated
The solution is Option C.
Yes; reflections and translations preserve lengths and angle measures, so the figures are congruent
What are Congruent Triangles?
Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
Let the triangle be represented as Triangle ΔJKL
Now , the triangle JKL is reflected across the line x = 0
So , the triangle is reflected along the y axis
And , when you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).
So , the x coordinates of triangle JKL changes
Now , the triangle is translated 5 units up
So , the values of the y coordinates gets increased by 5 units
And the transformed triangle is ΔJ'K'L'
The transformed triangles retains the shape as well the angle measures
From the congruent theorem of triangles
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
So , the triangle ΔJKL ≅ ΔJ'K'L'
Hence , the triangles are congruent and reflections or translations preserve lengths and angle measures
