The set of polynomials is closed under the operation of addition.

A: Which equation illustrates this concept?

B: Which statement correctly explains this concept?

Select one answer for question A and one answer for question B.

A: (x+4)+(4x−5)=49

A: (2x2−3x+1)(2x+2)=4x3−2x2−4x+2

A: (x−3)+(3x+2)=−2x−5

A: (3x−4)−(2x+2)=x−6

B: The sum of the polynomials (2x2−3x+1) and (2x+2) is a polynomial, 2x2−x+3, which shows there is closure under addition.

A: (2x2−3x+1)+(2x+2)=2x2−x+3

B: The sum of the polynomials (x+4) and (4x−5) is not a polynomial, 49, which does not show there is closure under addition.

B: The sum of the polynomials (x−3) and (3x+2) is a polynomial, −2x−5, which shows there is closure under addition.

B: The product of the polynomials (2x2−3x+1) and (2x+2) is a polynomial, 4x3−2x2−4x+2, which shows closure under addition.

B: The difference of the polynomials (3x−4) and (2x+2) is a polynomial, x−6, which shows there is closure under addition.

step-by-step explanation:

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

answer: e 9, 5.75

step-by-step explanation:

step 1

find the variation ab in the x coordinate

delta x=(x2-x1)=10-> 8 units

find the variation ab  in the y coordinate 

delta y=(y2-y1)=6-> 2 units

step 2

find the coordinates point c

  x coordinate 

cx=ax+delta x*2/> cx=2+8*(2/> cx=3

  y coordinate 

cy=ay+delta y*2/> cy=4+2*(2/> cy=4.25

the coordinates of point c are (3,4.25)

step 3

find the coordinates point d

  x  coordinate 

dx=ax+delta x*4/> dx=2+8*(4/> dx=4

  y  coordinate 

dy=ay+delta y*4/> dy=4+2*(4/> dy=4.5

the coordinates of point d are (4, 4.5)

step 4

find the coordinates point e

  x  coordinate 

ex=ax+delta x*4/> ex=2+8*(6/> ex=5

  y  coordinate 

ey=ay+delta y*4/> ey=4+2*(6/> ey=4.75

the coordinates of point e are (5, 4.75)

step 5

find the coordinates point f

  x  coordinate 

fx=ax+delta x*4/> fx=2+8*(8/> fx=6

  y  coordinate 

fy=ay+delta y*4/> fy=4+2*(8/> fy=5

the coordinates of point f are (6,5)

step 6

find the coordinates point g

  x  coordinate 

gx=ax+delta x*4/> gx=2+8*(10/> gx=7

  y  coordinate 

gy=ay+delta y*4/> gy=4+2*(10/> gy=5.25

the coordinates of point g are (7,5.25)

step 7

find the coordinates point h

  x  coordinate 

hx=ax+delta x*4/> hx=2+8*(12/> hx=8

  y  coordinate 

hy=ay+delta y*4/> hy=4+2*(12/> hy=5.5

the coordinates of point h are (8,5.5)

step 8

find the coordinates point i

  x  coordinate 

ix=ax+delta x*4/> ix=2+8*(14/> ix=9

  y  coordinate 

iy=ay+delta y*4/> iy=4+2*(14/> iy=5.75

the coordinates of point i are (9,5.75)
