Which series of transformations results in the image being congruent to the pre-image?
Alex73 [517]
Images of transformation are congruent if they were translated, mirrored/flipped or rotated

1)
(x, y) → (–x, –y) mirrored
(x, y) → (0.8x, 0.8y) scale->not congruent
(x, y) → (x, y + 5)

2)
(x, y) → (x, –y) mirrored
(x, y) → (–x, y) mirrored
(x, y) → (x + 1, y – 1) translation
-> is congruent

3)
(x, y) → (x + 5, y + 5) translation
(x, y) → (x, –y) mirror
(x, y) → (2x, y) scale-> not congruent

4)
(x, y) → (3x, 3y) scale->not congruent
(x, y) → (–x, y)
(x, y) → (x – 4, y)

so the second series of transformations is the only one with a congruent after image

Please help me in Math
Rashid [163]
1. You can add 7 units to both sides of the scale so it becomes a balance between x on the left and 21 on the right.
  x ___ 21

1A) The only number from the set that will keep the balance is x ∈ {21}
1B) The number on the right (21) will be more than x for x ∈ {0, 1, 7, 14}
1C) The number on the right (21) will be less than x for x ∈ {28, 30}


2A) (x +x +x) +(2 +4) = 102
  3x +6 = 102 . . . . . . . . simplified equation

2B) Solving the equation, you have
  3x = 102 -6
  x = 96/3 = 32
The number that could be a value of x is 32.

4 = 3x -x-4<br> I need steps to how to do this​
vesna_86 [32]

Step-by-step explanation:

so first you combine like terms , 3x-x-4=4 turns into 4x-4=4 then u add 4 to both sides [inverse operations]

4x-4=4

+4 +4

--------------

4x= 8

----------

4. 4

×=2

then u use inverse operations. agian and divide 4 into 8 and you get 2 !! x = 2
