Answer:
x ∈ {-0.465, 1.014}
Step-by-step explanation:
The equation can be cast in the form f(x) = 0, and solved easily using a graphing calculator. That shows x ≈ -0.465 and x ≈ 1.014. The same calculator can iterate the roots to full calculator precision.
__
The equation can be made a quadratic by the substitution ...
z = e^(2x)
Then we have ...

Answer:
number of members in 2006=190
230members on 2010
Step-by-step explanation:
2008-2006=2
20*2+150= 190 ans (1)
b)
20x+150=230
20x=230-150= 80
x= 80/20=4---ans (2)
-2x + 8. you multiply all the terms inside the parenthesis by the one outside of/attached to them. the reason it is +8 and not -8 is because the negatives cancel out to give you a positive.
