Let c=cost of chicken and d=cost of duck; 50c+30d=550 and 44c+36d=532.
So 5c+3d=55, 11c+9d=133.
Therefore 15c+9d=165, subtracting 11c+9d=133 we get: 4c=32 so c=8.
5c+3d=40+3d=55, so 3d=15 and d=5.
Cost of chicken is $8 and cost of duck is $5.
Answer:
3x+4y-12=0
y intercept = -constant term/coefficient. of y
= 12/4
=3
Answer:
B.
Step-by-step explanation:
Well we know that

so we can get the 2 outside of the radical

and we can get the x^2 outside too.

and we also can get y outside.
so we have:
![2x^{2}y\sqrt[5]{7xy^3}](https://tex.z-dn.net/?f=2x%5E%7B2%7Dy%5Csqrt%5B5%5D%7B7xy%5E3%7D)
it has gone up 4 lines and left -2 making it go for a (4,-2)
