Ab and bc form a right angle at point b. if a = (-3, -1) and b = (4, 4), what is the equation of bc ?

a.
x + 3y = 16
b.
2x + y = 12
c.
-7x − 5y = -48
d.
7x − 5y = 48

Well in order to lose a pound you would have to burn 1,500 calories. the more calories you burn the more weight you lose. in order to lose 2 pounds you would have to run 4 hours and 28 minutes.

So don't take my word i'm not exactly a mathematical person but i would assume a. because while selling the soap every month you increase in sells so you would by 11 percent. the you would get the factor 0.89 which if i had to guess would be the monthly profit over 11 probably wrong tho
