ANSWER
The solution that can be eliminated is
because time does not read backwards and hence can never he negative.
EXPLANATION
The reason why we eliminate the solution of
is that time cannot be negative.
While the ball is still in the hands of the quarterback, the time is
As soon as he throws the ball, the time starts reading forward.
When
the ball is no longer in the air. The ball took some time to travel through space before landing.
Time does not read backwards, that is the reason why the time taken for the ball to land cannot be negative.

Answer:
Step-by-step explanation:
Given
Round 0 1 2 3
Points 25 75 225 675
Required
Determine the equation
Let n = rounds and p = points.
So, we have:
The above shows a geometric progression.
So, we solve using
In
n = 0 and p = 25
Substitute these values in
In
n = 1 and p = 75
Substitute these values in
Substitute 25 for a
Make b the subject
So, we have:
and
The equation becomes
Answer:
The term that represent the amount of money she will spend on brownies is 2b
Step-by-step explanation:
Let
c ----> the number of cones
b ----> the number of brownies
we know that
The cost of desserts can be found using the expression
where
4c ----> is the term that represent the amount of money spend in cones
2b ----> is the term that represent the amount of money spend in brownies
5 ----> is the term that represent the amount of money spend in water
therefore
The term that represent the amount of money she will spend on brownies is 2b
That means ---> the number of brownies (b) multiplied by the cost of each brownie ($2)
