Answer:

9) e=-40 10) k=9

Step-by-step explanation:

9) e/4-10=-20  add 10 on both sides

e/4=-10  Multiply everything by 4

e=-40

10) 0.4k-4+1.6k=14   combine like terms

2k-4=14   Add 4 on both sides

2k=18   divide both sides by 2

k=9

What multiplies to give you 15 and adds to give you -8?
Nitella [24]

Answer:

The system of equations is:

        x + y = 15

           xy = 15

Step-by-step explanation:

solve the first for y and substitute in the second:

            y = 15-x

      x(15-x) = 15

     15x - x� = 15

15x - x� - 15 = 0

-x� + 15x - 15 = 0

x� - 15x + 15 = 0
