Answer:
y = -6
x = 1
Step-by-step explanation:
-x + 2y = -13
-x - 2y = 11
Sum the equations:
-x -x = -2x
+2y - 2y = 0
-13 + 11 = -2
then
-2x = -2
x = -2/-2
x = 1
from the first eq.
-x + 2y = -13
-1 + 2y = -13
2y = -13 + 1
2y = -12
y = -12/2
y = -6
check:
from the second eq.
-x -2y = 11
-1 -(2*-6) = 11
-1 -(-12) = 11
-1 + 12 = 11
The first number that you see between Michael and John is 40
Right now, x is only equal to two. Square both sides, and x^2 = 4. For some reason, if you want to take the square root of both sides, and you get x= +/- 2, ...

Step-by-step explanation:
Answer:
Step-by-step explanation:
they give you points that are variable instead of numbers
P1=(a,0)
P2=(0,b)
also a and b are the length of that side of the triangle
so
MP = 
then what ever a and b are.. you're set
to show your work you could use the distance formula which will give you the same thing above
MP = 
MP = 
which is just the formula above :)
