x = [-(-6) +/- sqrt((-6)^2 - 4*1 * 8))] / 2
= (6 + sqrt4) / 2 , ( 6 - sqrt4)/2
= 4 , 2
the difference of 5 times the cube of x cubed and the quotient of 4 times x and 3
5*x^3 - (4x/3)
Think about it this way, what is 5x3??? 15 right. Ok then what is 5x30???? 150. So the store should sell each soccer ball for $5 each:)
If your given slope is - 35, your equation starts off as y = - 35x + b
Now we plug in the point given and solve for b.
- 3 = - 35(6) + b
- 3 = - 210 + b
207 = b
So your equation is:
y = - 35x + 207
