Answer:
Option B, $1080
Step-by-step explanation:
<u>Step 1: Identify which option is correct
</u>
To find the initial amount of money you need to find the y-int or the value of y when the x value is 0.
So... when the x value is zero on this graph, the y-int or y value is 1080
Answer: Option B, $1080
The area of the rectangle is 105 square cm
<h3>How to determine the rectangle area?</h3>
Represent the dimensions of the rectangle with x and y
So, the length of the square would be:
Length = x - 2
Width = y + 6
The areas are then calculated as:
Rectangle = xy
Square = (x -2)(y + 6)
The relationship between the areas is:
(x -2)(y + 6) = 64 + xy
Expand
xy + 6x - 2y - 12 = 64 + xy
This gives
6x - 2y - 12 = 64
Add 12 to both sides
6x - 2y= 76
Divide through by 2
3x - y = 38
By trial by error, we have:
x = 15 and y = 7
The rectangle area is then calculated as:
Rectangle = xy
This gives
Rectangle = 15 * 7
Evaluate
Rectangle = 105
Hence, the area of the rectangle is 105 square cm

speed = distance/time
The average speed will be the change in distance divided by the change in time.
(d(10) -d(5))/(10 -5) = (80 -20)/5 = 12 . . . . meters per second
