Answer:
B) (5,-2)
Step-by-step explanation:
we have the equations:
We multiply the first equation by 3:
i will call this equation 1.
and we multiply the second equation by 2:
i will call this equation 2.
Now we subtract equation 2 from equation 1:
this is:
which gives:
and now that we know that 
we substitute this value in any of the original equations to find 
using 
we have:
so 
the answer is 
which is option B.
If this is a right triangle, then
where c is the hypotenuse which is ALWAYS THE LONGEST SIDE. Our longest side is 5, so we will set up Pythagorean's Theorem to see if the addition of the squares of a and b = the square of c:
. Squaring all of that and adding on the left gives us 25=25. Because this is true, we have proven the converse of the Pythagorean Theorem here and this is a right triangle.
Answer:
Step-by-step explanation:
S = 2
T = -2
so in S - T = 4. 2 - -2 = 4
IN S + T = 2 S + - 2 = 2
