Graph the system of equations to determine the solution. In your final answer, include your graph and the solution.
1 answer:
Answer:
Infinitely many solution.
Step-by-step explanation:
The given system is
x = y + 4
y = x - 4
To graph the first equation, we write it in slope-intercept form to get: to
x=y+4
This implies y=x-4.
This has a slope of 1 and a y-intercept of -4.
The graph of this function is shown in the attachment.
The second equation is y=x-4.
This equation is identical to first equation, so its graph coincides with the first one.
The system has infinitely many solution.

Answer:
Sum of money invested in corporate bonds = 30,000
Step-by-step explanation:
Total sum = 40,000
The rate of interest for corporate bonds = 10 % = 0.1
The rate of interest for municipal bonds = 6 % = 0.06
Total interest = 3600
Let sum of money invested in corporate bonds = x
The sum of money invested in municipal bonds = 40000 - x
× 0.1 × 1 + (
) × 0.06 × 1 = 3600
(0.1- 0.06) + 2400 = 3600
0.04 = 1200
= 30,000
Since x = sum of money invested in corporate bonds
So sum of money invested in corporate bonds = 30000
