i don't really know the answer to that but if you stick to it you will increase you're knowledge. good luck!
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
Find y:
8x-y=40
y = 8x - 40
slope = 8
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
Answer:
=2
Step-by-step explanation:
We have to make the fractions equal so we can add them
1
×4= 1
×3=
1
+
=2
