Answer:
C. 7,770.81
Step-by-step explanation:
8599 (1 - 0.025)^4
8599 (0.903)
7,764.897
*The decimal in the second step was not exact, but C is the closest answer.
Answer:
(A)y = -2, x-2y =6.
Step-by-step explanation:
On the graph, we have two lines:
- y = -2
- The line that goes through (0, -3) and (6, 0).
To determine the equation of the second line, we use the slope-intercept form: y=mx+b
Slope, m
So we have:
When x=0, y=-3
Therefore, the second equation is:
Rearranging: x-2y=6
The system of equations that is represented in the graph is:
The correct option is A.
Answer: if its 87% then its 0.87, but if its 87 then its 87.00

The area of the shaded region is going to be the area of the rectangle minus the area of the square.
Area of a rectangle is L * W.
A = L * W
A = (x + 10)(2x + 5)
A = x(2x + 5) + 10(2x + 5)
A = 2x^2 + 5x + 20x + 50
A = 2x^2 + 25x + 50 .....this is the area of the rectangle
area of a square is : A = a^2...where a is one side
A = (x + 1)^2
A = (x + 1)(x + 1)
A = x(x + 1) + 1(x + 1)
A = x^2 + x + x + 1
A = x^2 + 2x + 1
now we subtract the area of the square from the area of the rectangle to get the area of the shaded region.
2x^2 + 25x + 50 - (x^2 + 2x + 1) =
2x^2 + 25x + 50 - x^2 - 2x - 1 =
x^2 + 23x + 49 <== the area of the shaded region
