Answer:
A im pretty sure its a try it and let me know
Answer:
X=16
Step-by-step explanation:
10x-8=9x+8
First you have to simplify.
10x-9x=1x
So now the equation looks like this
x-8=8
Now you have to get x by itself
-8+8=0 and we have to do the same thing on both sides of the equal sign 8+8=16
The equation now looks like this x=16
And that's your answer

Use the product rule first:


Use the chain rule to compute the derivative of
. Let
and take
, so that by the chain rule




So we have

You can rewrite this a bit by factoring
, just to make it look neater:

829 rounded to the nearest tenth is 830
If the 9 would be a 4 or lower, then it would be 820, but in this case, it's a number larger than 5, so it would be 830.
