Identify the Incorrect Statements
(A) y ^ 2 + 9 is a linear and 'F' for false
(B) The terms linear equation and linear expression are same.
(C) if x is an even number, then the next odd
number is (2x + 1)
(D) If both sides of an equation is divided by the same (non-zero) positive number, then there is a change in equality.
(A) is incorrect. y^2 + 9 is a quadratic expression, not a linear expression.
(B) is incorrect. A linear equation and a linear expression are not the same. A linear equation is an equation that can be written in the form "ax + b = 0" where a and b are constants, while a linear expression is an algebraic expression involving variables and constants.
(C) is correct. The expression (2x + 1) represents the next odd number if x is an even number.
(D) is incorrect. If both sides of an equation are divided by the same (non-zero) positive number, the equality remains the same. For example, if we have the equation 2x = 10 and we divide both sides by 2, we get x = 5, which still satisfies the original equation.
