Step-by-step explanation:
the graph A is represents the ordered pairs.
Assuming that C is the hypotenuse...
The formula you want to use is:
a^2 + b^2 = c^2
We start by squaring 10, which is 100. 5^2 is 25. Now that we have the values, we can do the equation.
100+25=c^2 100+25=
Now, square root 
C= 11.180
Step-by-step explanation:
the value of x is 20 that's it good luck
Answer:
y= 2x-1/2 is x=.5 y + .25
2x-3y=4 is x = 1.5y + 2
Step-by-step explanation:
pretty sure thats it
<h2>
Hello!</h2>
The answer is:

<h2>
Why?</h2>
A multiple of a number is the repeated sum of itself, for example:
Multiple of the number 1 are: 1, 2, 3, 4, 5 and so...
Multiple of the number 3 are: 3, 6, 9, 12, 15 and so...
From the example we have:
Multiple of the number 3 are: Itself, (3+3), (3+3+3), (3+3+3+3), (3+3+3+3+3) and so...
So,
Multiple of
are:

Have a nice day!
