x^3(16x^2-1)
x^3(4x+1)(4x-1)
Answer:
situation 1 : flat rate of 50....1.50 per movie.....after 1 month her bill is 66.25
66.25 = 1.50x + 50
situation 2 : flat rate of 60....1.25 for every movie...
y = 1.25x + 60
both situations have a flat rate fee plus a charge for every movie. In situation 1, u can solve for x (the number of movies rented) because u know how much she was charged. However, in situation 2, without more information, u cannot solve this equation...what u would need to solve it would either be the number of movies rented or the total bill showing what she was charged. So basically, in situation 1, u are given more information then in situation 2.....enough information to be able to solve for the variable x...whereas, in situation 2, u are not given enough info to solve for a variable and get a numerical answer
