Which of the following equations demonstrate that the set of polynomials is not closed under the certain operations? O A. Subtraction: 3*+ **)-(-224 + 2) = 544 O B. Multiplication: (-5%+3)(-5) = 22 - 10/2 +28% -15 O C. Division: (1-5%+3) -(%-2) = %-3+ % - 2 D. Addition: (x2 + x) + (x + 1) = x2 + 2x+1 SUBMIT

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
