Answer:
The length of the focal width of the parabola is 1.
Step-by-step explanation:
Suppose we have a parabola with the following equation:
The centre is at point 
.
The length of the focal width is of |4p|.
In this question:
We want to place in the general format. So
Comparing, we have that 4p = 1. So the length of the focal width of the parabola is 1.
Answer:
the 1st, 2nd, and 4th one because those ordered pairs, the y axis is the same . sooo thats what makes it a non function .
Simplifying
a + 5 = -5a + 5
Reorder the terms:
5 + a = -5a + 5
Reorder the terms:
5 + a = 5 + -5a
Add '-5' to each side of the equation.
5 + -5 + a = 5 + -5 + -5a
Combine like terms: 5 + -5 = 0
0 + a = 5 + -5 + -5a
a = 5 + -5 + -5a
Combine like terms: 5 + -5 = 0
a = 0 + -5a
a = -5a
Solving
a = -5a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '5a' to each side of the equation.
a + 5a = -5a + 5a
Combine like terms: a + 5a = 6a
6a = -5a + 5a
Combine like terms: -5a + 5a = 0
6a = 0
Divide each side by '6'.
a = 0
Simplifying
a = 0
