What is the effect on the graph of the function () = 1 when () is replaced with () − 6?

Which of the following represents a number squared is equal to twenty more than nine times that number ? a) x squared = 9x + 20 b) x squared = 20x + 9 c) x squared > 9 + 20x d) x squared = 9 + x + 20

Express the following as a function of a single angle. cos(60) cos(-20) - sin(60) sin(-20)

Solve the equation: x - 9 = -6 + 5 a. 21 b. 7 c. 14 d. 2
