Answer:

r = - 6

Step-by-step explanation:

Given

6r + 7 = 13 + 7r ( collect terms in r on the left and numbers on the right )

Subtract 7r from both sides

- r + 7 = 13 ( subtract 7 from both sides )

- r = 6 ( multiply both sides by - 1 )

r = - 6

If e^(xy) = 2, then what is dy/dx at the point (1, ln2)?
love history [14]
E^(xy) = 2
(xdy/dx + y)e^(xy) = 0

What is .16 repeating as a simplified fraction?
Readme [11.4K]
I'm assuming this is 0.1666666...

Which in that case is 1/6.

(Just from memory)

To do 0.161616161616...

First, assign 0.161616... a variable, say it's x.

Now say 100x, what is it.

16.1616161616...

Now subtract x from 100x.

16.161616161616... - 0.16161616...

Or, 99x 

99x = 16 in this case right now

Divide both sides by 99

x = 16/99

So it really depends what's repeating, it's either 1/6 or 16/99.
