A. <span>2x + 5y= 10
5y= -2x+10
</span>-> y= -2/5x+2
b. The slope is 2
c. For the y intecpet, x is always 0
y= -2/5x+2
y= -2/5(0)+2
y=0+2
y=2
(0,2) is the y-interecpt

Answer:
Step-by-step explanation:
we know that
The <u><em>conjugate root theorem</em></u> states that if the complex number a + bi is a root of a polynomial P(x) in one variable with real coefficients, then the complex conjugate a - bi is also a root of that polynomial
In this problem we have that
The polynomial has roots 1 and (1+i)
so
by the conjugate root theorem
(1-i) is also a root of the polynomial
therefore
The lowest degree of the polynomial is 3
so
Remember that
The leading coefficient is 1
so
a=1
