Answer:
Step-by-step explanation:
5x+3y=1
4x-5y=4
--------------
4(5x+3y)=4(1)
-5(4x-5y)=-5(4)
----------------------
20x+12y=4
-20x+25y=-20
----------------------
37y=-16
y=-16/37
5x+3(-16/37)=1
5x-48/37=1
5x=1+48/37
5x=37/37+48/37
5x=85/37
x=(85/37)/5
x=(85/37)(1/5)
x=85/185
x=17/37
Answer: x=17/37, y=-16/37. (17/37, -16/37)
-----------------------------
5x+3y=1
8x-10y=4
-----------------
8(5x+3y)=8(1)
-5(8x-10y)=-5(4)
----------------------
40x+24y=8
-40x+50y=-20
----------------------
75y=-12
y=-12/75=-4/25
5x+3(-4/25)=1
5x-12/25=1
5x=1+12/25
5x=25/25+12/25
5x=37/25
x=(37/25)/5
x=(37/25)(1/5)
x=37/125
Answer: x=37/125, y=-4/25. (37/125, -4/25).
-------------------------------
5x+3y=1
9x-2y=5
---------------
2(5x+3y)=2(1)
3(9x-2y)=3(5)
---------------------
10x+6y=2
27x-6y=15
---------------
37x=17
x=17/37
5(17/37)+3y=1
85/37+3y=1
3y=1-85/37
3y=37/37-85/37
3y=-48/37
y=(-48/37)/3
y=(-48/37)(1/3)
y=-48/111
Answer: x=17/37, y=-48/111. (17/37, -48/111).

The answer I’m pretty sure will be -4. (-4+12-36)/7 = -28/7.
To answer this problem, we use the Pythagorean theorem which states that the square of the hypotenuse or the longest side is equal to the sum of the squares of the legs. Hence trying each option, we verify whether the dimensions are true to the right triangle theorem. In this case, the answer is B.
