Part A:
f(x)=30(1.2)^x
f(x)=45+3x
Part B: Neighborhood A is 74.6496, so that rounds to 75 homes, and Neighborhood C is exactly 60 homes
Part C:
i would graph them in a graphing calculator, and use the functions to see where the 2 lines intersect.
The x value for when they intersect (# of years) is 3.3207883, so approx. 3.3 years for them to be equal
The first one, the other graphs do not pass the Vertical line Test. they intersect at more than one point on the graph
let x represent how many friends Sumalee has.
40-2(x)=8
40 original balls - 2 to each friend = 8 balls left
(Y/4) +3 = 7
Subtract 3 from both sides:
Y/4 = 4
Multiply both sides by 4
Y = 16
