Answer:

Step-by-step explanation:
we know that
The standard equation of a horizontal parabola is equal to

where
(h,k) is the vertex
(h+p,k) is the focus
In this problem we have
(h,k)=(0,0) ----> vertex at origin
(h+p,k)=(-4,0)
so
h+p=-4
p=-4
substitute the values


Answer:
There will be 1 solution to the system of equations.
Step-by-step explanation:
y = 6x - 7
y = 53x + 13
Since the two equations have different slopes and different y-intercepts, there will be 1 solution to the system of equations.
tadah!

Answer:
0.25p+20
Step-by-step explanation:
Since there is a set up fee of $20 then you would have to add it to the value of what 0.25p will be. Since p represents every square foot of the walls and you would multiply p by 0.25 every square foot is $0.25 then 0.25p+20 would accurately represent the problem
