Answer:
B
Step-by-step explanation:
Because of the exponent in x²
We want to find out how much it costs for each pound of feed
For chicken feed 12 divided by 8.40
$1.43 for 1 pound of chicken feed
For goat feed 75 divided by 60
$1.25 for 1 pound of goat feed
For dog feed 50 divided by 37.50
$1.33 for 1 pound of dog feed
For pig feed 80 divided by 62.80
$1.27 for 1 pound of pig feed
When reviewing all the answers per pound for feed, chicken feed is the most expensive per pound.
Hope this helps:)
Answer:
Step-by-step explanation:
2/5x + 6=3/4x-8
This can be calculated easily.
As any two digit number can be written in the following form:
N= 10x +y
If we reverse the number now, it would become:
N' = 10y + x
So if we subtract one from the other, we should obtain 18 ( as mentioned in the question ).
N-N'= 18
=> x-y = 2
Thus, any number whose digits differ by two would be an aswer to the question.
The only numbers which satisfy this are : 13,24,35,46,57,68,79
But this would not be true for any 3 or more digit number.
Answer:
Step-by-step explanation:
![(x_{1} , y_{1}) = (-1,6)\\\\(x_{2},y_{2}) = ( -3, 0)\\\\Slope =\dfrac{y_{2}-y_{1}}{x_{2}-x_1}}\\\\\\=\dfrac{0-6}{-3+1}\\\\\\=\dfrac{-6}{-2}\\\\=3](https://tex.z-dn.net/?f=%28x_%7B1%7D%20%2C%20y_%7B1%7D%29%20%3D%20%28-1%2C6%29%5C%5C%5C%5C%28x_%7B2%7D%2Cy_%7B2%7D%29%20%3D%20%28%20-3%2C%200%29%5C%5C%5C%5CSlope%20%3D%5Cdfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_1%7D%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B0-6%7D%7B-3%2B1%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B-6%7D%7B-2%7D%5C%5C%5C%5C%3D3)
Equation of the line: y= mx +b
y = 3x + b
Substitute ((-1 , 6) in the above equation
6 = 3*(-1) + b
6 = -3+b
6 +3 = b
b = 9
y = 3x + 9
