Which of the following equations demonstrate that the set of polynomials is
not closed under the certain operations?
A. Multiplication: 3x4 + x°)(-2x4 + x) = -6x8 + x?
+ to
B. Division: (x2 + 2x) = (x + 1) = x+
х
x +1
C. Multiplication: (x2 + 2x)(x + 1) = x+3x2+2x
D. Addition: 3x4 + x°) + (-2x+ + x) = x4 + 2x3

i think is g(1)=-1.

hope that i can

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

i believe that the slope of the line is -5

step-by-step explanation:
