<u>Algebra I</u>
- Solving systems of equations by graphing
Step-by-step explanation:
The solution set to any systems of equations is where the 2 lines intersect. According to the graph, we see that the 2 lines intersect at (-3, 5). Therefore, our answer is A.
The standard form: ax + by = c
and your equation is: -2x + 3y = - 5 (Yes this is written in standard form)
To Find :
Net worth of Rachel.
Solution :
Net worth is given by the (sum of all the assets she owns) -( total amount of loans she have ).

Therefore, net worth of Rachel is $ 363587.
Hence, this is the required solution.
Answer:
15 days
Step-by-step explanation:
Let x be the number of days needed for B to complete the job. Then x-5 is the number of days needed for A to complete the job.
In 1 day,
- A completes
of all work; - B completes
of all work.
Hence, in 1 day both A and B complete
of all work. A and B working together can do a work in 6 days. Then

Solve this equation:

If
then
that is impossible. So, B needs 15 days to complete the work alone.
