k is a polynomial or degree 3. k has a root of multiplicity 2 at c=2,k(-3)=0,and k(0)=-8.64. find an algebraic equation for k.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100
