Ummm I am no help sorry I only have one brain cell
That would be the median....u need to list the numbers in order to find the middle number (median)
If -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)
<h3>How to determine the true statement?</h3>
The root of the polynomial function is given as:
-3 + i
The above root is a complex root.
If a polynomial has a complex root, then the conjugate of the root is also a root of the function
The conjugate of -3 + i is -3 - i
Hence, if -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)

The ANSWER for this question is D.14
Answer: x = -3 y = 2 So (-3,2)
Step-by-step explanation:
- x + 3y = 9 Multiply everything by 2 then add to the second equation.
2x + 5y = 4
<u>-2x +6y =18 </u> then 2x-2x=0 Add the other terms and solve for y.
11y = 22 divide both sides by 11 yo get y = 2 Substitute that into either one and solve for x.
2x + 5y = 4
2x + 5(2) = 4
2x + 10 = 4 subtract 10 from both sides 2x = 4 -10
2x = -6 so divide both sides by 2 to get x = -3
