Answer:
no solution
Step-by-step explanation:
Equating the right sides of both equations, that is
6x + 9 = 6x + 2 ( subtract 9 from both sides )
6x = 6x - 7 ( subtract 6x from both sides )
0 = - 7 ← not possible
This indicates there is no solution to the system of equations
Answer:
63*42=2646
22*22=484
Area of Shaded Gray portion=2646-484=2162

Answer:
4 seconds
Step-by-step explanation:
using the vertex formula of a quadratic,
, where (h,k) is the vertex
h is height and t is time in seconds
the vertex (maximum height) of the dolphin is (h,k) or (0.5, 2)
Height of 1/2
time of 2 seconds
it will take 2 additional seconds to reach the water again.
this can also be solved using quadratic equation, but since it was already set up in vertex form, i'd use that.
