Answer 1

An 8-car Ferris wheel is shaped like a regular octagon. Does the Ferris wheel have rotational symmetry? Explain.

Answer 2

Triangle STU below is translated right 2 units and 3 units down. What are the coordinates of the vertices of the image?

A coordinate grid with triangle S T U drawn on the grid is shown.The x-axis is between negative 12 and 4 with interval marks representing one unit, and the y-axis is between negative 4 and 14 with interval marks representing one unit. Triangle S T U is drawn in red with vertex S at left-parenthesis negative 6 comma 10 right-parenthesis, vertex T at left-parenthesis negative 9 comma 3 right-parenthesis, and vertex U at left-parenthesis negative 3 comma 3 right-parenthesis.
A. S’(−9, 12), T’(−12, 5), U’(−6, 5)
B. S’(−4, 7), T’(−7, 0), U’(−1, 0)
C. S’(−8, 13), T’(−11, 6), U’(−5, 6
D. S’(−4, 10), T’(−7, 3), U’(−1, 3)

Answer 3

Choose the graph that represents the equation y = x – 2.
A. graph
B. graph
C. graph

Answer 4

Which graph shows the image of the triangle below after it is reflected over the x-axis?

graphThe x-axis is between negative 4 and 4 with interval marks representing one unit, and the y-axis is between negative 5 and 5 with interval marks representing one unit. A triangle is drawn in red with vertices at left-parenthesis 1 comma 1 right-parenthesis, left-parenthesis 3 comma 1 right-parenthesis, and left-parenthesis 1 comma 3 right-parenthesis.
A. graph
B. graph
C. graph
D. graph

Answer 5

Determine which ordered pair is a solution of y = x2–2.

(5, 21), (–5, 24), (–1, –1), (–2, 6)

A. (–2, 6)
B. (5, 21)
C. (–1, –1)
D. (–5, 24)

Answer 6

bot you can only chose one for that question

Answer 7

Without graphing, tell whether the line containing (6, –3) and (0, –8) is horizontal, vertical, or neither.
A. neither
B. vertical
C. horizontal

Answer 8

As a computer programmer, you have to define the movements of a battleship across a virtual grid. Will you program the transformation from the original position (Figure I) to the final position (Figure II) as a translation, reflection, or rotation?

Two scalene triangles labeled 'upper I' and 'upper I upper I' are shown. Triangle upper I upper I is a mirror image of triangle upper I.
A. translation
B. reflection
C. rotation

Answer 9

Does the figure have rotational symmetry? If it does, find the angle of rotation. (the figure is a basic star)

Answer 10

An 8-car Ferris wheel is shaped like a regular octagon. Does the Ferris wheel have rotational
symmetry? Explain in a simple matter

Answer 11

Draw the image of the figure after a counter-clockwise rotation of 90º about O.
