Answer:
From the Pythagorean theorem...
[ distance between (a, 7) and (2, 1) ]2 = [a - 2]2 + [7 - 1]2
And they tell us that the distance equals 3√5 , so
[ 3√5 ]2 = [a - 2]2 + [7 - 1]2
45 = [a - 2]2 + 36
9 = [a - 2]2
±√9 = a - 2
± 3 = a - 2
± 3 + 2 = a
a = 3 + 2 = 5 or a = -3 + 2 = -1
and
5 + -1 = 4

Answer:
2
Step-by-step explanation:
We can interpret the fraction 
as division: 2/3 divided by 1/3. What that expression asks is "how many times does 1/3 go into 2/3?" And that number is 2.
Answer:11.39
Step-by-step explanation:
Answer:
Last option: Keep the base the same and then subtract the exponents.
Step-by-step explanation:
There is a property called "Quotient of power property".
This property states that if you need to divide two powers with the same base, you must keep the same base and subtract the exponents:
Then, you need to apply this property to the expression 
to simplify it.
Therefore, you get that the expression simplified is:
<span>M divides JK into two parts with lengths in a ratio of 1:3
so JM:MK is either 3:1 or 1:3
before solving for M, need to find mid-pt of JK, point L
L is at (-4+8)/2 and (11-1)/2 so L is at (2,5)
mid-pt of JL is at (-4+2)/2 and (11+5)/2 so it is at (-1,8)
and mid-pt of LK is at (8+2)/2 and (-1+5)/2 so it is at (5,2)
note that these pts are the fourths. They </span><span>divide the segment into fourths, so the three-quarter segment is indeed thrice as long as the quarter segment. They are the ans for pt M.
M is (-1,8) or (5,2)
