Answer:
$720
Step-by-step explanation:
First tutor = 30 x 10 = $300
Second tutor = 30 x 14 = $420

Answer:
A
Step-by-step explanation:
By vertical line test, if you draw any vertical line, except for A, all graph meet at more than two points. So, graph A represents y as a function of x.
Since the diagonals of a parallelogram bisect each other, it follows that:


The correct answer is 4cm
Difference quotient = [f(x+h) - f(x)]/h
[-5(x+h) -3 - (-5x -3)]/h
[-5x -5h -3 + 5x +3]/h
[-5h]/h
-5
