Answer:
9, 40, and 42
Step-by-step explanation:
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:
(a) Neither
(a) Perpemdicular
Step-by-step explanation:
Required
Determine the relationship between given lines
(a)

and

An equation written in form:
has the slope:

So, in both equations:


For both lines to be parallel

This is false in this case, because:

For both lines to be perpendicular

This is false in this case, because:

(b)

and

Write equations in form:


Divide by 5



Divide by 2

In both equations:


For both lines to be parallel

This is false in this case, because:

For both lines to be perpendicular

This is true in this case, because:

Cancel out 2 and 5
