Sarah is bringing treats to her middle school class on her birthday. The number of treats she brings in is based on the number of students in her class. The function t(s) = 2s, where s is the number of students in her class and t(s) is the number of treats she will need to bring. What does t(4) = 8 mean?
If there are 8 students, she will need to bring 4 treats.
If there are 4 students, she will need to bring 8 treats.
If there are 2 students, she will need to bring 8 treats.
If there are 4 students, she will need to bring 2 treats.
How is triangle ABC being translated to triangle A'B'C'?
left 8, up 3
left 4, up 9
right 8, down 3
right 4, down 9
In a translation, the pre-image and image are ___________. Check all that apply (2).
congruent
similar
parallel to each other
perpendicular to each other
Triangle ABC has vertices at A(6, 1) B(1, 7) and C(-3, -2). The translation to create triangle A'B'C' is (x, y) goes to (x - 1, y + 2). Which will be the coordinates of triangle A'B'C'?
A'(5, 2), B'(0, -4), C'(0, 9)
A'(5, 3), B'(0, -4), C'(0, 8)
A'(5, 3), B'(0, 9), C'(-4, 0)
A'(5, 2), B'(1, -3), C'(0, 9)
(x, y) ----> (x + 2, y - 3)
Write the rule for this translation:
Slide 3 up and 2 right
(x, y)---->(x + 3, y + 2)
(x, y)-----> (x + 2, y + 3)
(x, y)----> (x - 2, y + 3)
(x, y)----> (x - 3, y + 2)
What geometric form do rotations move points along?
Rays
Parallel Lines
Perpendicular Lines
Circular Arcs
A rotation does not preserve congruence.
True
False
(x,y)-->(y,-x)
Write a function rule using function notation that will transform the figure ABCDE to A'B'C'D'E'.
(x, y) → (-y, -x)
(x, y) → (x, -y)
(x, y) → (-x, -y)
(x, y) → (-y, x)
