Y=-x+5<br> Y=x+1<br> Solve the system

Elis [28]

Answer:

$y = - x + 5 \\ y = x + 1 \\ - x + 5 = x + 1 \\ - 2x = - 4 \\ x = 2 \\ y = 2 + 1 = 3 \\ y = 3$

Therefore the answer is:

x=2; y=3

Good luck!

Find a third-degree polynomial equation with rational coefficients that has roots –4 and 2 + i

ella [17]

If it has rational coefients and is a polygon
if a+bi is a root then a-bi is also a root

the roots are -4 and 2+i
so then 2-i must also be a root

if the rots of a poly are r1 and r2 then the factors are
f(x)=(x-r1)(x-r2)

roots are -4 and 2+i and 2-i

f(x)=(x-(-4))(x-(2+i))(x-(2-i))
f(x)=(x+4)(x-2-i)(x-2+i)
expand
f(x)=x³-11x+20
