The answer to your question is 1/4
1)
I:y=3x-4
II:9x-3y=14
substitute y into II:
9x-3*(3x-4)=14
9x-9x+12=14
12=14
this is obviously not equal so there is no solution, the lines are parallel
2)
I:y=4x+6
II:5x-y=6
substitute y into II:
5x-(4x+6)=6
5x-4x-6=6
x=12
substiute x into II:
5*12-y=6
-y=6-60
-y=-54
y=54
the solution is (12,54)

Answer:
Option D. 50 ft
Step-by-step explanation:
we know that
The area of the figure is equal to the area of three rectangles
so
![A=18x+(48-36)(32-11)+(18)(32)](https://tex.z-dn.net/?f=A%3D18x%2B%2848-36%29%2832-11%29%2B%2818%29%2832%29)
![A=18x+(12)(21)+(18)(32)\\A=18x+828](https://tex.z-dn.net/?f=A%3D18x%2B%2812%29%2821%29%2B%2818%29%2832%29%5C%5CA%3D18x%2B828)
Remember that the area is given
![A= 1,728\ ft^2](https://tex.z-dn.net/?f=A%3D%201%2C728%5C%20ft%5E2)
so
![18x+828=1,728](https://tex.z-dn.net/?f=18x%2B828%3D1%2C728)
solve for x
![18x=1,728-828\\18x=900\\x=50\ ft](https://tex.z-dn.net/?f=18x%3D1%2C728-828%5C%5C18x%3D900%5C%5Cx%3D50%5C%20ft)
