I'm 99% positive these are right, not 100%, but...
Given the formula, all you have to do is input 10 into the places where there are x.
500*10-20*10^2
500*10-20*100
5000-2000
3000
So the profit is $3000! Hope this helped!
5y-15x=-20
5y=15x-20
y=3x-20/3
Slope = 3
Slope Intercept Form
y-y1=m(x-x1)
Therefore y-(-6)=3(x-3)
y+6=3x-9
y=3x-15
I cannot say I'm sure as I haven't learned this myself in class, however, I think it would also be 60. Apologies if I'm incorrect!!
