Answer:
C=135 D= 25
Step-by-step explanation:
240,240 is a lot of students for a marching band!
lets use S as a variable for students
s=240/40
240/40
s=6
So there would be 6 students in each row.
$214.60-15=199.60
199.60/20= 9.98
Each cd was $9.98
It would be 29 because 8hours - 45minutes =7hours 15 minutes
7hours 15minutes divided by 15 minutes =29
Answer:
The equation of the axis of symmetry is equal to

Step-by-step explanation:
we have

This is the equation of a vertical parabola written in vertex form open upward (because the leading coefficient is positive)
The vertex represent a minimum
The axis of symmetry is equal to the x-coordinate of the vertex
we have that
The vertex is the point (10,-6)
The x-coordinate of the vertex is 10
therefore
The equation of the axis of symmetry is equal to
