Accumulated depreciation=8*2000=$16,000
Graphing is a good method when you have small integers or fractions as your slope.
Substitution is a good method when you have two equations, and when one of the coefficient of the variables is one.
Linear combinations is a good method when you have the same coefficient for the same variable in 2 different equations.

' s equals fraction numerator negative 10'.
It should be - (-10) = 'positive 10'.
[tex}r - 5 \frac{5}6 + 5\frac{5}6 = 10 +5\frac{5}6{/tex]
It's 4:3 because if its 24:18 you can break it down by dividing 6 from both of them to get 4:3
