2x - 3y + 6 = 0
<u> - 6 - 6</u>
2x - 3y = -6
2x - 2x - 3y = -6 - 2x
<u>-3y</u> = <u>-6 - 2x</u>
-3 -3
y = 2 + ²/₃x
3/173 3 green and total of marbles into fraction and its in simplest form
Use this equation y = a (1 - b)^x
Where a is the initial population and b is the decay factor: 40/100 = 0.4
Therefore, the answer is that the decay factor b is 0.4.
This table shows some figures using the decay factor.
year decrease population
0 0 a(1 - 0.4)^0 = a
1 a*0.4 a (1 - 0.4)^1 = a*0.6 = 0.6a
2 0.6a*0.4 a(1 - 0.4)^2 = a(0.6)^2 = 0.36a
3 0.36a*0.4 a(1 -0.4)^3= a(0.6)^3 = 0.216a
You can't. One side and one angle is never enough to define a unique triangle.
If the side opposite the right angle is 150mm, the other 2 sides could be . . .
-- 75 and 129.9
-- 100 and 111.8
-- 110 and 101.98
-- 120 and 90
-- 130 and 74.83
-- both 106.07
or any one of an infinite number of other possibilities.
You need to know one more side, or one more angle.
