Answer:
7.5 ft
Step-by-step explanation:
divide 5 by 2 -- 5 ÷ 2 = 2.5
now multiply 2.5 by 3 -- 2.5 × 3 = 7.5
Answer:
A
Step-by-step explanation:
cannot be B because the slope is positive, not negative
cannot be D because the y-intercept is 8, not negative 8
30*4 = 120 (120 oranges=total oranges needed)
120/20=6
Scott need 6 boxes of oranges
we know that
The equation of a vertical parabola in vertex form is equal to

where
(h,k) is the vertex
if
-----> then the parabola open upward (the vertex is a minimum)
if
-----> then the parabola open downward (the vertex is a maximum)
The axis of symmetry is equal to

In this problem let's analyze two cases
First case

the vertex is the point 

so
-----> then the parabola open upward (the vertex is a minimum)
The axis of symmetry is equal to

Second case

the vertex is the point 

so
-----> then the parabola open upward (the vertex is a minimum)
The axis of symmetry is equal to
