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
The algebraic equation is used to determine the costs of each bag of lemons is 8x = $39.62 - $6.74
According to the question,
Cost of 1 bag of lemons = $x
Cost of 8 bags of lemons = 8*x = 8x
Cost of 8 bags of lemons = Total cost - cost of the egg
8x = $39.62 - $6.74
Hence, the algebraic equation is used to determine the costs of each bag of lemons is 8x = $39.62 - $6.74.

Answer:
righ angle tringle
Step-by-step explanation:
because 90 degree angle is only in right angle tringle,we can not creat this angle in other tringle
Just adding the 2 equations eliminates the terms in x (7x + -7x = 0) giving:-
0 + 9y = 9
y = 1
Plug this into the first equation:-
7x + 4(1) = -3
7x = -7
x = -1
Answer x = -1 and y = 1.
