Answer:
A.) −2y + 10
Step-by-step explanation:
−x − 2y = −10
Add 2y to both sides.
-x = 2y - 10
Multiply both sides by -1.
x = -2y + 10
The key piece of information for these questions is the Fundamental Theorem of Algebra, which states that a degree n polynomial has n complex roots. A complex root can be either real or imaginary.
First question, regarding the polynomial y = x^3 - 3x^2 + 16x - 48:
We know there is one real root, the x-intercept.
Since it's a third degree polynomial, there are three complex roots in total.
Therefore, there is one real root and two imaginary roots.
Answer is B
Second question:
You probably can guess the answer, now that you know the Fundamental Theorem of Alegebra:
There are 3 real zeros, each with multiplicity one, meaning each root only happens once. It's a 5th degree polynomial, so there are a total of 5 roots, implying 2 imaginary roots.
Answer is C) 3 real and 2 imaginary zeroes.
Answer:
I believe it is Option 1
Step-by-step explanation:
Since the fourth root of 81 will be 3 and of 16 will be 2.
Answer:
Step-by-step explanation:
The answer is b
