Arianne- 18 and Jan-12. Reason being because if you subtract 6 from 18 that would make arianne 12, and if you subtract 6 from 12 it would make Jan 6. And half of 12 is 6.

Solve for n using the additive identity property.

tangare [24]

<em>The answer is:</em>

$\boxed{n=5}$

<h2>Explanation:</h2>

The additive identity property states that if you add any real number to zero or add zero to any real number, you will get the same real number back. In other words:

$a+0=0+a=a \ For \ any \ real \ number \ a$

Here we have that:

$5+0=n$

So by the mentioned property:

$5+0=0+5=5$

In other words:

$\boxed{n=5}$

Find the slope of the line through the pair of points a (2,-3) p(2,9)

Katarina [22]

(x₁,y₁) = (2,-3)
(x₂,y₂) = (2,9)

To determine the slope using two points lie on the line, we could use the following formula
m = $\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

plug in the numbers
m = $\dfrac{9-(-3)}{2-2}$
m = $\dfrac{9+3}{0}$
m = $\dfrac{12}{0}$
m = undefined

The slope is undefined, the line is vertical

Nola hiked down a trail at a steady rate for 10 minutes. Her change in elevation was -200 ft. Then she continued to hike down fo

umka21 [38]

Her first rate was faster. The 10 minutes with a change in elevation of -200ft.
In order to solve this you need to have the same minutes. In this problem, I just simply took the 10 minutes and the -200ft and doubled it. Now both rates have 20 minutes. The first rate would have gone -400ft in 20 minutes while the second rate was only -300ft in 20 minutes. I hope this wasn't confusing, and I'm willing to explain more.
