What is the solution of the system use substitution. 4x-y=5 3x-y=2
a.(3,7)
b.(7,-7)
,7)
d.(3/4,2/5)?

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
