Answer:
y = -x - 2
Step-by-step explanation:
y = mx + c
m = (-1-3)/(-1-(-5)) = -4/4 = -1
y = -x + c
(-1,-1)
-1 = -(-1) + c
c = -2
y = -x - 2

Answer:
$67,516
Step-by-step explanation:
"Depreciates" means the value is getting smaller. The function that describes the situation is a <em>decay</em> function:
y= a(1-r)^x
Here, a=150000, r = 0.07, and x=11. The value is predicted to be ...
y = 150000(1 -0.07)^11 = 150000(0.93^11) = 67,515.53
The house is worth about $67,516 in 2013.
Answer:
$ 31.925
Step-by-step explanation:
Final Value = a (1+r)^n
a = initial amount, r = appreciation rate, n = no. of time periods
a = 5 , r = 5% = 0.05 , n = 38
5 (1+0.05)^38
5 (1.05)^38
5 (6.385)
= 31.925
