Answer:
13
Step-by-step explanation:
-2+15=13 Degrees
There are 16 ounces in a pound, so 8 ounces would be half a pound (0.5 lb)
-50 + 60
= 10
10 - 70
= -60
-60 + 80
20
so he made a profit of $20
Define
v = value after t years.
Therefore the linear model is
v = mt + c
where
m = depreciation rate
t = years since purchase
c = constant
When t=0, v = 20,000, therefore
20000 = m(0) + c
c = 20000
When t=10, v = 2000, therefore
2000 = 10m + 20000
-18000 = 10m
m = -1800
Answer:
The linear model is
v = -1800t + 20000
U= 2.5 which is rounded to the nearest tenth.
