Which of the following shows that polynomials are closed under subtraction when polynomial x + 5 is subtracted from 3x2 + 2x − 6
Art [367]
For this case we have the following polynomials:
 P = 3x ^ 2 + 2x - 6

Q = x + 5
 By subtracting both polynomials we have:
 P - Q = (3x ^ 2 + 2x - 6) - (x + 5)

 What we must do is subtract terms of the same degree.
 We have then:
 P - Q = 3x ^ 2 + (2x - x) + (-6 - 5)

P - Q = 3x ^ 2 + x - 11
 Answer:
 
3x ^ 2 + x - 11 will be a polynomial

PLEASE helppp. What equation describes a line that is perpendicular y=-2/7x+5 and has the same y-intercept as y = 3x - 2?
svp [43]

Answer:

y = 7/2 -2

Step-by-step explanation:

if the slope of the first problem is -2/7 then its perpendicular is 7/2 (the exact opposite) and since the y- intercept is the b in Y= mx +b the intercept of the equation you’re trying to find is -2
