Answer:
x= 3/5 or x= 0.6
Step-by-step explanation:
Think i got it
E= 75
F= 90
G= 25
u = 1+3e<span>-x</span>
so that (Don't forget to use the chain rule on e<span>-x</span>.)
du = 3e<span>-x</span>(-1) dx = -3e<span>-x</span> dx ,
or
(-1/3)du = e<span>-x</span> dx .
However, how can we replace the term e<span>-3x</span> in the original problem ? Note that
.
From the u-substitution
u = 1+3e<span>-x</span> ,
we can "back substitute" with
e<span>-x</span> = (1/3)(u-1) .
Substitute into the original problem, replacing all forms of x, getting
(Recall that (AB)C = AC BC .)
Y = x² - 11x + 30
y = x² - 5x - 6x + 30
y = x(x - 5) - 6(x - 5)
y = (x - 5)(x - 6)
