X^2+2x= -8
x^2+2x+1= -8+1
(x+1)^2= -8+1
(x+1)^2=-7
x+1= √-7
The answer is No Solution because the root of a negative number is not a real number.

$40 average
Step-by-step explanation:
500-300=200
200/5=40
The solution set of the given inequality has a domain of (-∞, ∞) and the vertex(h,k) = (1, -9)
<h3>What is the solution set for inequality?</h3>
The solution set for inequality is the set of all solutions for which the inequality is defined. It can also be represented in an interval notation.
Given that:
By rewriting the equation in the parabola standard form 4p(y-k) = (x - h)², we have:
![\mathbf{4\times \dfrac{1}{4}(y-(-9)) = (x-1)^2}](https://tex.z-dn.net/?f=%5Cmathbf%7B4%5Ctimes%20%5Cdfrac%7B1%7D%7B4%7D%28y-%28-9%29%29%20%3D%20%28x-1%29%5E2%7D)
Therefore, the parabola properties are:
- The solution set of the domain is (-∞, ∞)
- Vertex(h,k) = (1, -9)
- Focal length |p| = 1/4
