First we distribute $\frac{1}{5}$ into $n$ and $-\frac{1}{7}$ .

$\frac{1}{5} * n = \frac{1}{5} n$
$\frac{1}{5} * -\frac{1}{7} = - \frac{1}{35}$

That makes the left side of the equation

$\frac{1}{5} n - \frac{1}{35} = \frac{1}{6} n$

Now we subtract $\frac{1}{5}n$ from $\frac{1}{6} n$ , which makes $\frac{1}{30}$

Now the equation is

$-\frac{1}{35} = -\frac{1}{30n}$

Our goal is to isolate $n$ , so we both sides by 30

$30* -\frac{1}{35} = - \frac{1}{30}n * 30$

That will make the equation

$- \frac{30}{35} = -n$

We multiply -1 on both sides of the equation:

$\frac{30}{35} = n$

Finally we simplify $\frac{30}{35}$ , which makes $\frac{6}{7}$

So the answer is $n = \frac{6}{7}$

Answer:

4th option - over the interval (4,7) the local minimum is -7

Step-by-step explanation:

There's only one local minimum in this graph and it's the one between (4,7), so this is the only plausible answer.

Find the equation of the line passing through the indicated two points in standard form. (-3, 9) and (0, -5)

alexandr402 [8]

The formula is y-y0=m(x-x0)
So we plug in the Y's and the X's given:
-5-9=m(0-(-3)) >>>> -14=m(3)>>>>> m=-14/3

The next formula is y=mx+b , choose any point to use for X and Y: I'm gonna choose (0,-5)

-5=-14/3(0)+b >>> b=-5
Your formula is: y=-14/3x-5
