That is where the function equals 0
0=5x-20
add 20 both sides
20=5x
divide 5
4=x
the zero is at x=4
(4,0)
6 ≤ 5(x - 4) -2(-x + 1)
First, distribute 5 to all terms within the first parenthesis, and -2 to all terms in the second parenthesis
6 ≤ (5x - 20 + 2x -2)
Combine like terms
6 ≤ (5x + 2x - 20 - 2)
6 ≤ 7x - 22
Isolate the x. Do the opposite of PEMDAS. Note that what you do to one side you to the other.
Add 22 to both sides
6 (+22) ≤ 7x - 22 (+22)
28 ≤ 7x
Divide 7 from both sides
28/7 ≤ 7x/7
28/7 ≤ x
4 ≤ x is your answer
Use a closed dot (because of the equal underneath) on 4, and go left with an arrow

Answer:
Any point on the line.
Step-by-step explanation:
x+6=0 is a straight line, and this line is infinite. You can pick three points on the line and the middle point is the vertex. This vertex can be any point on the line because there are an infinite amount of points to choose.
