I think the right triangle is on the top of the picture aisle that is the only one that look right to me
Answer:

Step-by-step explanation:
Given
___ 
Required
Fill in the gap
First, we need to solve 

So:
___ 
becomes
3.162 ___ 5
3.162 lies between 3 and 4
So, we can say that
lies between 3 and 4
Since:
3.162 is less than 5, the gap can be filled with <.
So, we have: 3.162 < 5
False because I looked it up online
Answer:
(0,-2)
Step-by-step explanation:
one way to solve...
3x - y = 2 --> *4
-2x + 4y = -8
multiply the first equation by 4
12x - 4y = 8
-2x + 4y = -8
-----------------
10x = 0
x = 0
y = -2
this method is called elimination
another way to solve...
3x - y = 2 simplify for y to get y = 3x - 2
-2x + 4y = -8 substitute y into this equation to solve for x
-2x + 4(3x - 2) = -8
-2x + 12x - 8 = -8
10x = 0
x = 0
y = -2
substitution
alsoo if there are options, just plug in the numbers to the correct variables
Step-by-step explanation:
2 x (16 + (10 + 3) - 3) - 22
2 x (16 + 13 - 3) - 22
2 x 26 - 22
2 x 4
= 8
