Betty rearranged the movies on her shelving unit after a few days. She placed equal numbers of movies on the bottom 3 shelves, and 10 movies on each of the top two shelves. If x is the number of movies on each of the bottom 3 shelves, the expression for the total number of movies on the shelving unit is 3x + 20. How many movies are on the shelving unit if there are 11 movies on each of the bottom 3 shelves?

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
