Step-by-step explanation:
go it right on edge

means you shade the part above the line, and

means you shade the part under the line.
If it has an equal bar under it, like this:

Answer:
v = ± 5
Step-by-step explanation:
given 5v² - 125 = 0 ( add 125 to both sides )
5v² = 125 ( divide both sides by 5 )
v² = 25 ( take the square root of both sides )
v = ±
= ± 5
The correct way to write slope intercept is y=3x+4
