Answer:

x = 5

Step-by-step explanation:

3x - 2 = x + 8

Subtract x from each side

3x-x - 2 = x-x + 8

2x -2 = 8

Add 2 to each side

2x-2+2 = 8+2

2x = 10

Divide each side by 2

2x/2 =10/2

x = 5

Answer: x = 5

Step-by-step explanation:

3x - 2 = x + 8- from this, move -2 across the '=', which makes it now a positive 2. It will now look like 3x = x + 10. Now you should move the x across, which will make it negative, so it will now look like 2x = 10. Now all you have to do is divide 10 by 2, and you will get x, which equals 5

Answer:

Step-by-step explanation:

8(3x - 6) = 6(4x + 8)

24x - 48 = 24x + 48

24x - 24x = 48 + 48

0 ≠ 96

this will have NO SOLUTIONS....because no matter what value u put in for x, they will never be equal.

A polynomial function is given.

faltersainse [42]

Answer:

Step-by-step explanation:

Look what happens if you do the multiplication of P(x):

P(x) = x^3 - 9x

This is a variation of the basic cubing function y = x^3.

The graph begins in QIII and ends in QI; in other words, if you go left the graph drops; if you go right, the graph rises (without limit, in both cases).
