Well I believe the correct equation would be 3x-y+7 because the y- intercept is 7 which is positive. That could only mean that the answer with a positive 7 is correct.
hope this helps!!

Answer:
The beam should be placed 8 feet from the center.
Step-by-step explanation:
The struts are y = √(x + 8) and y = √(x − 4). The struts are 2 feet apart at the location of the beam:
√(x + 8) − √(x − 4) = 2
Solving:
√(x + 8) = 2 + √(x − 4)
x + 8 = 4 + 4√(x − 4) + x − 4
8 = 4√(x − 4)
2 = √(x − 4)
x − 4 = 4
x = 8

Answer:
W=32
L=70
Step-by-step explanation:
L=2w+6
204=2L+2W
204=2w+2(2w+6)
204=2w+4w+12
192=6w
w=32
L=2(32)+6
L=70
