Answer:
12y + 5x = 169
Step-by-step explanation:
Differentiate wrt x
2x + 2y(dy/dx) = 0
dy/dx = -x/y
At (5,12)
m = -5/12
y = (-5/12)x + c
12 = -25/12 + c
c = 169/12
y = (-5/12)x + 169/12
12y + 5x = 169
Yes! A ton is 2000 pounds and the tow truck can pull 5 tons, so you multiply 5 by 2000. That is 10,000 pounds and is more than 9,000 pounds which is how much the truck weighs. So the tow truck can tow the truck
