3x-y=2....(i)
2x-y=3.....(ii)
now adding the eqn I and ii ,
3x-y=2
2x-y=3
+ + +
5x=5
x=1
Now substituting the value of x in eqn I
3×1-y=2
3-y=2
-y=-1
y=1
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:
3/8 of the box is left so 6 ounces is left.
Step-by-step explanation:
Make the 1/4, 2/8 then add 2/8 by 3/8 to get 5/8 then subtract 8/8 by 5/8 to get 3/8 then multiply it by 2 to get 6/16.
So the answer is 6/16 or 6.
