Answer:
The amount of money originally borrowed by Mr. Peterson is $6,800.
Step-by-step explanation:
Let us assume the money borrowed originally = P
Rate of interest = 5%
Time = 3 years
S interest = $1020
Simple Interest = 
Substituting the all values, we get:
⇒ P = $6,800
Hence, the amount of money originally borrowed by Mr. Peterson is $6,800.
Answer:
Yes
Step-by-step explanation:
To prove that 1/8 is less than 1/7, the easiest way to do is convert it to decimals
1/8 = 0.125
1/7 = 0.14285714285 (Estimated - 0.14)
0.14 is a larger number than 0.125, therefore 1/8 is less than 1/7
Answer:
no
Step-by-step explanation:
This is the answer to the problem. You basically substitute the -6 in for the f(x)
Answer: (2,11)
Step-by-step explanation:
To find the point where the functions will intersect, we want to find the place that they are equal to each other. We do this by setting the equations equal to each other.
5x+1=-2x+15 [add both sides by 2x]
7x+1=15 [subtract both sides by 1]
7x=14 [divide both sides by 7]
x=2
Now, we know that the functions intersect at x=2. To find the point, we would plug x back into both equations to ensure that the points are the same.
f(2)=5(2)+1 [multiply]
f(2)=10+1 [add]
f(2)=11
The point on f(x) is (2,11).
g(2)=-2(2)+15 [multiply]
g(2)=-4+15 [add]
g(2)=11
The point on g(x) is (2,11).
Since the point at x=2 is the same for f(x) and g(x), we know that the graph intersects at (2,11).
