Answer:
(2y - 5) (3y^2 - 4)
Step-by-step explanation:
Group and factor by using the Greatest Common Factor (GCF).
6y^3 - 15y^2 - 8y + 20
Simply multiply the terms inside the first pair of parenthesis, by the terms in the second pair of parenthesis.
2y x 3y^2 = 6y^3
2y x (-4) = 8y
-5 x 3y^2 = 15y^2
-5 x (-4) = 20
6y^3 - 8y -15y^2 + 20
Now, simply simplify the problem!
(2y - 5) (3y^2 - 4)
A (-3, -1)
You know this because QIII is in the bottom left corner and both numbers are negative
The decimal equivalent is 0.5
The percent equivalent is 20 percent

Answer:
To understand the equation of a line which is perpendicular to x axis, let us consider the figure given below. In the figure above, clearly the line L is perpendicular to x-axis and passing through the value "c" on x- axis. Hence, the equation of a line perpendicular to x axis is x = c.
