Step-by-step explanation:
it's been a while since i've done proofs but i think this is right
Answer:
y=-2x+2
Step-by-step explanation:
Given line is-
x-2y=7
we know,
equation of line perpendicular to ax+by=c is bx-ay=k
So, equation of line perpendicular to x-2y=7
is given by -2x-y=k
Now, the line -2x-y=k passes through (5,-8)
So, we get
-2(5)-(-8)=k
or, -10+8=k
or, -2=k
So, k=-2
Using the k value we get,
Equation of the line is-
-2x-y=-2
multiplying by -1
2x+y=2
or, y=-2x+2
This is the slope intercept form of the line.
Answer:
Step-by-step explanation:
Prime numbers have only one factor pair, the number itself and 1. Some polynomials can be factored and some cannot be so a polynomial is a prime polynomial if it can't be factored into the standard linear form of (x+a)((x+b).
For the given polynomial x^3+3x^2+2x+6
Re-arranging the Polynomial to find out whether it could be factored or not
x^3+2x+3x^2+6=0
x(x^2+2) +3 (x^2+2)=0
(x+3)(x^2+2)=0
x+3=0 and x^2+2=0
x=-3, x^2= -2
x=-3, x=sqrt(-2), x= -sqrt(-2)
As the polynomial is factorable it is not prime
Acute is less then 90 degrees, right is 90 degrees, and obtuse is more then 90 degrees.
