Answer:
A. 
Step-by-step explanation:
The given parabola has vertex at (2,-5).
The equation of this parabola in vertex form is given by:
, where (h,k)=(2,-5) is the vertex of the parabola.
We substitute the values to get:
The graph passes through; (0,3).
Hence the equation of the parabola is
We expand this to get:
Since the outward region was shaded, the corresponding inequality is
The correct answer is A

Answer:
bus = 43
van 12
Step-by-step explanation:
This can be solved using simultaneous equations
Let v represent the number of students that a van carries
Let b represent the number of students that a bus carries
the following equations can be derived from the question
3v + 2b = 122 eqn 1
5v + 3b = 189 eqn 2
Multiply eqn 1 by 5 and eqn 2 by 3
15v + 10b = 610 eqn 3
15v + 9b = 567 eqn 4
Subtract equation 4 from 3
b = 43
Substitute for b in equation 1
3v + 2(43) = 122
solve for v
v = 12
