Answer:
- x + y ≤ 25
- 1.75x + 2.50y ≤ 75
Step-by-step explanation:
- Paperback books = x
- Hard cover books = y
<u>Number of books:</u>
<u>Cost of books:</u>
The system above is the one we need
5. To figure this out you must find when y = 0
-16t^2 = -200
t^2 = 12.5
Square root
t = 3.54 C
6.
Axis of symetry = -.5 (always a vertical line down vertex)
Vertex = (-.5, -6.5) (the minimum of the graph)
B
7. To find maximum height you must find the vertex
The maximum height is 549 feet after 5.75 seconds
C
9. Solve for X
x^2 = 1
Square root
X = plus or minus 1
A
