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
Answer:
1 hour 13 min
Step-by-step explanation:
Given data
Start time= 6:35 PM
Finish time= 7:22 PM
Hence the time spent is
=7:22-6:35
=1:13
Hence the time spent is 1 hour 13 min
Answer:
4 by 6
Step-by-step explanation:
Answer:
b^2+17
Step-by-step explanation:
2^3 is 8 (2*2*2=8)
b^2 stays the same bcz its a variable and we don't know its value
3^2 is 9 (3*3=9)
SO just substitute,
8+b^2+9
b^2+17
Answer:
<h2>
The interest ethan will pay is $164.25</h2>
Step-by-step explanation:
To calculate the interest paid by ethan on the borrowed bike using the formula.
Simple Interest = Principal * rate * time/100
Principal = $2,190, rate = 2.5%, time = 3years
On substitution
SI = 
The interest ethan will pay is $164.25
