Answer:

x = 25

Step-by-step explanation:

2/5x - 1 = 9

Add 1 to both sides

2/5x = 10

Multiply by 5 on both sides

2x = 50

Divide by 2 on both sides

x = 25

Check the answer:

Plug in 25 for x

2/5(25) - 1 = 9

10 - 1 = 9

9 = 9

The answer is correct.

Write the opposite polynomial for -3x ^3+12x-4
ValentinkaMS [17]

Answer:

3x³ - 12x + 4  

Step-by-step explanation:

The opposite of a polynomial P is -P.

You find the opposite of P by multiplying it by -1.

 P = -3x³ + 12x - 4

-P = (-1)( -3x³ +       12x   -      4)     Distribute -1 to each term

    = (-1)(-3x³) + (-1)(12x)  - (-1)(4)     Multiply each coefficient by -1

    =       3x³  +     (-12)x -     (-4)

   =       3x³  -        12x   +     4
