Answer:

<h2><u>FALSE</u></h2>

Step-by-step explanation:

To find the slope you need to pick two points. Points (2,4) and (4,3) are the points I used. (It does not really matter what points you chose). Now we have to follow the formula to find the slope. The formula can be seen below

Slope (m) = ΔY/ΔX

Now solve

ΔX = 4 – 2 = 2

ΔY = 3 – 4 = -1

Once you have solved it, you take it and make it a fraction

-1/2 = -0.5

How can I solve this: |n| ≥ n

valina [46]

$|n| \geq n$

For $n\leq 0$

$|n| \geq n \Leftrightarrow -n\geq n \Rightarrow 2n\leq0 \Rightarrow n\leq0$

For $n>0$

$|n| \geq n \Leftrightarrow n\geq n \Rightarrow 0\geq0\Rightarrow x\in\mathbb{R}$

$x>0 \vee x\leq 0 \Rightarrow \boxed{x\in\mathbb{R}}$

-------------------------------------------------------------

$|n| \leq n$

For $n\leq0$

$|n|\leq n\Leftrightarrow -n\leq n \Rightarrow 2n\geq 0 \Rightarrow n\geq 0\\
n\geq 0 \wedge n\leq 0 \Rightarrow n=0$

For $n>0$

$|n|\leq n \Leftrightarrow n\leq n \Rightarrow 0 \leq 0\Rightarrow n\in \mathbb{R}\\
n\in \mathbb{R} \wedge n>0 \Rightarrow n>0$

$n>0 \vee n=0 \Rightarrow \boxed{x\geq0}$

The Outside Club went on a 20-mile backpacking trek in Yellowstone National Park. They covered 6 1/4 mi the first day and 8 1/2

White raven [17]

Answer:

5 1/4 miles

Step-by-step explanation:

Adding 8 1/2 and 6 1/4 together, you should get 14 3/4. Subtract this from 20, and you get 5 1/4 miles.

How would u find the answer idk if they would still be the same and you just have to find that one missing angle?

ivolga24 [154]

Well... with the information you are given you just have to assume they are congruent triangles. The first picture looks like a right triangle, but the angle is 100 not 90... so it wouldn't actually look like that.

So for the missing angle all you do is 180= 100+ 55 + x

x=25

Then just match up the angles with the other triangle, they would be the same. K with F, J with G, and so on
