The vertex of the parabola below is at the point (5,-3). Which of the equations below could be the one for this parabola?
10+
(5,-3)
-10
A. y=-3(x - 5)2-3
O B. x = 3(y + 3)2 + 5
C. x = 3(y- 5)2 - 3
ОО
D. x = -3(y + 3)2 + 5

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

-2/

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is
