Step-by-step explanation:
The standard form of an equation of a circle:
(h, k) - center
r - radius
We have the center (-5, 0) and the radius r = 8. Substitute:
Answer:
inequality form: x -2 or x > 3
interval notation form: (-∞,-2] ∪ (3,∞)
Step-by-step explanation:
I attached a picture that shows all the work. You begin by isolating then solving for x on both sides. Then form a solution using the information found out about x. For example, you can combine the found inequalities for x to solve that x must be GREATER than 3 while being LESS than -2. Using that you can form an line and make a line. Remember, when writing in interval notation form you always begin from the left to the right (in reference) to the number line.
