Answer:
neither
Step-by-step explanation:
(-3,1), (-7,-2)
Slope of the line containing point (-3,1), (-7,-2) is
Slope of the line containing point (2,-1), (8,4) is
Slope of both the lines are not same, so they are not parallel
the slope of both the lines are not negative reciprocal of one another
So they are not perpendicular
Hence they are neither parallel nor perpendicular.
Answer:
x will be 120 degrees
Step-by-step explanation:
I will loves easy questions!
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
Answer:
i'm pretty sure it's called a number line
Step-by-step explanation:
The numbers that don't have a "minus" on them are called positive numbers, the ones that do are called negative numbers. Same numbers but different values.
