Answer:
option: A
Step-by-step explanation:
" if for a polynomial with rational coefficients has irrational roots then these irrational roots will always appear in pair " .
we are given that 
and 
are two roots of a polynomial equation with rational coefficients, then it's complex conjugate is also a root of this polynomial equation i.e. ' 
' and ' 
' are also roots of this polynomial equation.
Hence, option A is correct.
Answer:
225%
Step-by-step explanation:
You can figure the percentage change from ...
percentage change = ((new value)/(old value) -1) × 100%
= (26/8 -1) × 100% = (3.25 -1) × 100% = 225%
First we are going to start by subtracting 3-10 and that gives us 7 so then you divide 7 by 4”3 and you get 2.3
Step-by-step explanation:
I answered that already.
Answer:
D. 
Step-by-step explanation:
we are given
Firstly, it is reflected over x-axis
we know that for reflection about x-axis , we can replace y as -y
we get
now, it is vertical shift up by 4 units
so, we can add 4 to y-value
we get
