Try this: Principal times (1+interest rate as a decimal fraction)^(number of yrs)
In this case, Principal = $28,000; interest rate = -0.25; # of years = 1
So Decrease in value = $28,000 (0.75)^1 = $21,000.
4.16 I think if I did the math right
Answer:
35 in^2
Step-by-step explanation:
The area of a trapezoid is the average of the bases times the height.
Base 1: 8, Base 2: 6, Height: 5
(8 + 6)/2 = 7
7 * 5 = 35 in^2
The Solution:
From the graph, there is a point of intersection between the graphs of the two equations in the system. This implies that:
There is a viable solution to the given system of equations at the point where the two lines intersect, that is, at the point (26,34).
So, the correct answer is [option 3]
