-6x^2+4x
my reasoning:
eliminate the opposites (5 & -5)
collect the like terms (-8x^2 & + 2x^2)
collect the like terms again (-3x &+7x)
Gotta graph this one
Zeros are $.586 and $3.414 and the profit is zero when these are the prices
Maximum profit when the dogs are 2 bucks
If you are trying to find the interest, it would be $60.00. To get this just multiply everything. Hope this helps!!! :)

The perpendicular line would have a slope of 1/3.
Perpendicular lines have opposite and reciprocal slopes.
To do the opposite, take the original slope (-3) and change the sign (3).
To do the reciprocal, take the slope we changed (3) and flip it as a fraction (1/3).
This gives us a new slope of 1/3.
