Mathematics
Formulate the situation as a system of two linear equations in two variables. Be sure to state clearly the meaning of your x- and y-variables. Solve the system by the elimination method. Be sure to state your final answer in terms of the original question. A lawyer has found 60 investors for a limited partnership to purchase an inner-city apartment building, with each contributing either $5,000 or $10,000. If the partnership raised $425,000, then how many investors contributed $5,000 and how many contributed $10,000?

Step-by-step explanation:
We have been given that a polynomial function
models the motion of a roller coaster. Every root of the polynomial represent when the roller coaster is at the ground level.
In order to find all the potential values of x when roller coaster is at the ground level, we find the zeroes of the polynomial by factoring it as shown below:
The zeroes of this polynomial occur when either
or 
.
The equation
have no real solutions. Therefore, the only time when the roller coaster is at the ground is at
