True. When you distribute the equation it equals 12-x

Answer: -1</h3>
=======================================================
Explanation:
First we need to find the slope of this given line.
The two points on here are (0,-3) and (3,0)
Apply the slope formula
m = (y2-y1)/(x2 - x1)
m = (0-(-3))/(3-0)
m = (0+3)/(3-0)
m = 3/3
m = 1
The slope of the given line is 1. The negative reciprocal of this is -1, which is the perpendicular slope.
Side Note: Any two perpendicular lines always have their slope multiply to -1, as long as neither line is vertical.

Answer: The answer is 48 cows.
Step-by-step explanation: Given that a farmer bought a number of equally priced cows at $480. After 3 died, the farmer sold the remaining cows for a total of $495 and the price per cow was $1 more when he sold them than when he bought them. We need to find the number of cows he bought originally.
Let, 'x' be the number of cows he bought originally each at a price of '$y'.
Then, we have
Subtracting the first equation from the second, we have
This gives, y = 10 or y = -16. Since price of a cow cannot be negative, so y = 10.
Thus,
Thus, the total number of cows originally bought is 48.
