(B) 
Step-by-step explanation:
A polynomial is the expression which consists of addition, subtraction, multiplication with any variables or constants but the division with a variable is not considered as a polynomial.
Since consists of division of -3 with a variable, therefore it is not a polynomial, rest all other options are polynomial as they involve addition,multiplication with variables.
In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.
A = {0, 1, 2, 3}
C = {0, a, 2, b}
A ∩ C = {0, 2} → E)
A set of the same elements from the set A and the set C.
Answer:
A) 5x + 2y = 22
B) -2x + 6y = 3 We'll multiply A) by -3
A) -15x -6y = -66 Then we'll add B)
B) -2x + 6y = 3
-17x = -63
x = 3.7058823529
y = 1.7352941178
