Answer:
-5+√3i is the given root so -5-√3i must be the other root
Step-by-step explanation:
We know that complex roots must come in pairs. The pairs are complex conjugates. (a+bi) and (a-bi)
You are missing a sign between -5 and the square root
So if - 5+ sqrt(3) i is a root, then -5 - sqrt(3) i must be a root
if -5 - sqrt(3)i is a root, then -5 + sqrt(3)i must be a root.
I will assume you missed a + sign
-5+√3i is the given root so -5-√3i must be the other root
Answer:
Option C, (6, 8.4)
Step-by-step explanation:
It would be option C because all of the other ones, both the y and x value is almost the same. (2, 2.1) (4, 3.8) and (9, 9) are all really close in y and x values. While (6, 8.4) has a y value that is over 2 more than x.
Answer: Option C, (6, 8.4)
Turner Middle School
620 students
31 teachers
Green Middle School
950 students
38 teachers
If you want the ratios of teachers to teachers and students to students for Turner to Green...
the ratio of students to students is 620/950 = 0.65
the ratio of teachers to teachers is 31/38 = 0.82
Answer:
-2n - 12
Step-by-step explanation:
Combine like terms. Note that each term has one variable (n). Also note that one negative sign and one positive sign results in a negative sign.
-6n + (-12) + 4n = -6n + 4n - 12 = -2n - 12
-2n - 12 is your answer
