Triangle JKL is reflected across x = 0 and then translated 5 units up to create △JʹKʹLʹ. Are the two figures congruent? Explain.
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.
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

Answer:
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.
y = -3x -3

What is her score for the game?
A 16.25
B 13.75
C. 15
D. 14.25
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.

together for $4.00 each. Write a system of linear equations that represents this
situation. Will you and your friend spend the same amount of money? Explain.
Answer:
y= 4x + 11 and no.
Step-by-step explanation:
Because you spent the 11 dollars extra and rode the rides meanwhile your friend only went on the rides. If (x) equals the amount of rides and (y) means the total amount. Then your friends equation with be y= 4x. But, you already spent 11 dollars additionally so therefore your equation with be y=4x + 11.
