³⁾2/3 = 6/9 ≠ 1/9
Answer:
22
Step-by-step explanation:
15-(-7)
15+7=22
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 .)
252 seeds
Since there is 42 seeds in each of the 12 bags you need to multiply 42 and 12
42 × 12 = 504
So in total she has 504 seeds, now you need to split that in half by dividing 504 and 2
504 ÷ 2 = 252
Therefore she has 252 seeds left
Hope this helps! :)
