Answer:
A is the answer.
Step-by-step explanation:
We have
![\sqrt[3]{56 {x}^{7} {y}^{5} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B56%20%7Bx%7D%5E%7B7%7D%20%7By%7D%5E%7B5%7D%20%20%7D%20)
Factor the radical by taking perfect squares of the real numbers and the exponents.
56 can be made up of perfect 8, x^7 can be made up of x^6 and y^5 can be made up of y^3. So we get
![\sqrt[3]{8 {x}^{6} {y}^{3} \times \sqrt{7xy {}^{2} } }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B8%20%20%7Bx%7D%5E%7B6%7D%20%20%7By%7D%5E%7B3%7D%20%20%5Ctimes%20%20%5Csqrt%7B7xy%20%7B%7D%5E%7B2%7D%20%7D%20%7D%20)
Take the cube root of 8x^6y^3.
Which is 2x^2y.
![2 {x}^{2} y \sqrt[3]{7xy {}^{2} }](https://tex.z-dn.net/?f=2%20%7Bx%7D%5E%7B2%7D%20y%20%20%5Csqrt%5B3%5D%7B7xy%20%7B%7D%5E%7B2%7D%20%7D%20)
A is the answer.

Hope this Helped!
Y = 2x - 3
y = -x+ 9
2x-3 = -x+9
2x+x = 9+2
3x = 12
x = 12/3
x = 4
y = 2(4)-3
y = 8-3 = 5
Mark on (4,5) & draw the line from origin.

![y = 0.25x + 40](https://tex.z-dn.net/?f=y%20%3D%200.25x%20%2B%2040)
![60 = 0.25x + 40](https://tex.z-dn.net/?f=60%20%3D%200.25x%20%2B%2040)
![60 - 40 = 0.25x + 40 - 40](https://tex.z-dn.net/?f=60%20-%2040%20%3D%200.25x%20%2B%2040%20-%2040)
![20 = 0.25x](https://tex.z-dn.net/?f=20%20%3D%200.25x)
