X+ 3y = 7 x - 3y = 1 solve the system of equations. a) x = 4, y = 1 b) x = 1, y = 4 c) x = - 2 3 , y = 3 d) x = 3, y = - 2 3

How do i do this? i don’t understand

Select the correct answer from each drop-down menu. consider the following polynomials equations. 3x^2(x-1) and -3x^3+ 4x^2-2x+1 perform each operation and determine if the result is a polynomial. is the result of a + b a polynomial? yes or no is the result of a - b a polynomial? yes or no is the result of a · b a polynomial? yes or no
