Kim performed a transformation on rectangle ABCD to create rectangle A'B'C'D', as shown in the figure below:
Rectangles ABCD and A prime B prime C prime and D prime are shown. A is at negative 1, 2. B is at negative 1, 5. C is at negative 3, 5. D is at negative 3, 2. A prime is at negative 2, negative 1. B prime is at negative 5, negative 1. C prime is at negative 5, negative 3. D prime is at negative 2, negative 3.
What transformation did Kim perform to create rectangle A'B'C'D'?
Rotation of 270 degrees counterclockwise about the origin
Reflection across the line of symmetry of the figure
Reflection across the y‐axis
Rotation of 90 degrees counterclockwise about the origin
cost of tshirt is 40
50=x + y
let X -cost of shirt
Y -cost of tie
X = Y+30
50=Y + 30 + Y
80= 2 Y
Let...x be the number of boysx + 26 be the number of girls
Getting the number of boys.
Now, let's get the number of girls by substituting.
The word phrase "Two-thirds the difference of a and b" can be written as...
