To simplify you simply find common variables and add them together to get 56a^3b^3
-2/3x is the slope. the full problem is y=-2/3x + 3
∠BAD is acute.
Hope my answer helped u :)
The starting value is 20,300, and the value is decreasing by 9.5% each year.
Because it decreases by 9.5% each year based on the previous amount, we use an exponential decay model.
A decrease by 9.5% corresponds to multiplying by 91.5% each year.
We write . We plug in 11 years for t.
