An online gaming club has a one-time registration fee of $14.95 and charges $0.69 to buy each game. if sammy has $60.00 to join the club and buy games, what is the maximum number of games she can buy?

65 games

Step-by-step explanation:

After paying for the registration fee she will have $45.05 left. If games cost $0.69, she could purchase 65 games which cost $44.85 and have $0.20 left

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
