Answer:
The area of half of the garden in square meters
Step-by-step explanation:
The factorization of A is y = (x - 8)(x + 7).
The factorization of B is y = (x + 1)(x - 4)(x - 5)
In order to find these, you must first find where each graph crosses the x-axis. In the first problem it does so at 8 and -7. In order to find the correct parenthesis for those, you need to write it out as a statement and then solve for 0.
x = 8 ---> subtract 8 from both sides
x - 8 = 0
This means we use (x - 8) in our factorization.
You then need to repeat the process until you have all the pieces. In the second problem, there will be 3 instead of 2 since it crosses the axis 3 times.
If there only one person then the total would be $40.25
Since, A 3-mi cab ride costs $7.30 and a 8-mi cab ride costs $15.30.
In the information given above, we can consider these as the coordinate points on the axes.
Let (c, d) be the coordinates , where 'c' represents the total cost and 'd' represents the distance traveled.
Cost is on the 'y' axis and distance is on the 'x' axis.
Now, let the first point on the coordinate axes be (3, 7.30) and the other point is given by (8, 15.30).
For the given points say
and
, equation of line is given by:
where m(slope) is given by
.
The equation of line for the given points is:
![(c-7.30) = (\frac{15.30-7.30}{8-3})(d-3)](https://tex.z-dn.net/?f=%28c-7.30%29%20%3D%20%28%5Cfrac%7B15.30-7.30%7D%7B8-3%7D%29%28d-3%29)
![(c-7.30) = 1.6(d-3)](https://tex.z-dn.net/?f=%28c-7.30%29%20%3D%201.6%28d-3%29)
![c-7.30 = 1.6d-4.8](https://tex.z-dn.net/?f=c-7.30%20%3D%201.6d-4.8)
![c-1.6d=2.5](https://tex.z-dn.net/?f=c-1.6d%3D2.5)
So, c = 1.6d+2.5 is the required linear equation that models a relationship between cost c and distance d.
If a = 10, then the equation would be 10+6.
The answer would be 16.
Hope this helps! :D
