C= the price of a cheeseburger and l = the price of a lemonade:
Divide the second equation by -2 to begin the process of solving by elimination:
Now that we have c, 4, we can plug it in to one of the equations to find l:
So, each cheeseburger is $4 and each lemonade is $1. The final answer is:
1 cheeseburger and 2 cups of lemonade would cost $6.

Answer:
The object will reach its highest point 0.5 seconds after it has been thrown.
Step-by-step explanation:
The object reaches its maximum height when velocity is equal to zero, the velocity is the derivative of function height. That is:
(1)
Where is the velocity of the object at time
, in feet per seconds.
If we know that and
, then the time when object reaches its highest point is:
The object will reach its highest point 0.5 seconds after it has been thrown.
