C. The first is a solution, but the second is not.
5x - y/3 = 13 ; (2,-9)
substitute the letters:
5(2) - (-9/3) = 13
10 - (-3) = 13 : note that deducting a number with a negative sign turns both sign as positive.
10 + 3 = 13 ;
13 = 13
5x - y/3 = 13 ; (3,-6)
5(3) - (-6/3) = 13
15 - (-2) = 13
15 + 2 = 13
17 = 13 not equal. not a solution
AB = 3 because 3x+9 = 6x so 3x = 9 so x=3
Hope this helps!
Each year, the forest decreases in area by 7.25%, which means that 92.75% of the forest remains each year.
With this, we can write a basic exponential decay equation:
4900*(0.9275)^t
Where t is the number of years past.
When you plug in 5 for t, the result shows that 3363.3005km^2 offorest will remain.
