Y = a(1 - r)^t
Y = 8,000(1 - 0.06)^t
You can see a = 8,000
As the fish population starts at 8,000
3-6+12=9
Steps
you have to add first so you must add -6+12 which will be -6
Then you will take 3 - - 6 which will make it 9
They are equal because
1 yd=3ft
25 yds= x feet
x= 25*3
feet=75
About 3, because there are 5280 feet in a mile, so 2 miles would be 10560, and 3 would be 15840, and that is the closest you will get, because the 4th miles would be 21120.
Gradient= y1-y2/x1-x2
=(10-6)/(4-3)=4
y=4x+c
6=4(3)+c
c=-6
equation is D
