<u>Answer:</u>
Annual Income of A=
and
Annual Income of B=
<u>Step-by-step explanation:</u>
<u>Given Data:</u>
Ratio of annual income of A and B=4:3
Ratio of expenditures of A and B=3:2
Saving of A and B=1000
<u>Required:</u> Annual Income of A and B=?
<u>Solution:</u>
If ratio of income of A and B is 4:3
then let Income of A=
and Income of B=
If ratio of expenditure of A and B is 3:2
then let expenditure of A= and expenditure of B=
Therefore,
...........
and 
..........
subtracting Eq(1) and Eq(2), we get
putting 
in Eq(1), we get value of 
as
because x and y are equal in Eq (3)
Now, Annual Income of A=
and Annual Income of B=
Answer: The ball hits the ground at 5 s
Step-by-step explanation:
The question seems incomplete and there is not enough data. However, we can work with the following function to understand this problem:
(1)
Where 
models the height of the ball in meters and 
the time.
Now, let's find the time when the ball Sara kicked hits the ground (this is when 
):
(2)
Rearranging the equation:
(3)
Dividing both sides of the equation by 
:
(4)
This quadratic equation can be written in the form 
, and can be solved with the following formula:
(5)
Where:
Substituting the known values:
(6)
Solving we have the following result:
This means the ball hit the ground 5 seconds after it was kicked by Sara.
<span>–122 < –3(–2 – 8x) – 8x
-122< 6 + 24x - 8x
-122 < 6 + 16x
-122 - 6 < 16x
-128<16x
-128/16<x
-8<x
x>-8
answer is </span>B. x > –8
