Michaele used the subtraction property to justify the first step in solving an equation. The original equation was 2x + 4 = 10. What could the equation have transformed into after this step? A) 2x = 14 B) 2x + 6 = 12
C) 2x = 6 D) x + 2 = 5

F(x) = x2 − 9, and g(x) = x − 3 f(x) = x2 − 4x + 3, and g(x) = x − 3 f(x) = x2 + 4x − 5, and g(x) = x − 1 f(x) = x2 − 16, and g(x) = x − 4 h(x) = x + 5 arrowright h(x) = x + 3 arrowright h(x) = x + 4 arrowright h(x) = x − 1 arrowright
