Answer:

Step-by-step explanation:

First you must notice each of them share an x value in the exponent. So with that being said x is your GCF or in otherwords greatest common factor.

So you have an x(x^3-6x^2+9x)

you must take x from all of them inside the ( )

because x is your gcf :)

So x(x^2-6x+9) Now you use the trail and method error

to get (x-3 )(x-3 )you need two numbers that multiply to 9 but add up to -6 so... that would hmmm -3 and -3 cause -3*-3=9 and -3+-3=-6

don't forget your GCF bring it down because it's always in your answer

x(x-3)(x-3)

or..

x(x-3)^2 both are the same thing

ANSWER CAN BE

x(x-3)(x-3) OR x(x-3)^2

Both are the same thing just written different! You're welcome!

System of equations <br> Y=-1/2x+4 3x-4y=12
Kaylis [27]

Answer:

{x,y} = {8,3}

Step-by-step explanation:

// Solve equation [2] for the variable  y

 [2]    4y = 2x - 4

 [2]    y = x/2 - 1

// Plug this in for variable  y  in equation [1]

  [1]    3x - 4•(x /2-1) = 12

  [1]    x = 8

// Solve equation [1] for the variable  x

  [1]    x = 8

// By now we know this much :

   x = 8

   y = x/2-1

// Use the  x  value to solve for  y

   y = (/2)(8)-1 = 3

Use the number line below, where RS = 7y +3, ST = 5y +8, and RT = 83.
Llana [10]

Answer:

Step-by-step explanation:

Given the vectors based on the number line as RS = 7y +3, ST = 5y +8, and RT = 83, the equation RS+ST = RT will be used to get the unknown.

Substituting the given equation into the expression we will have;

7y +3+5y +8 = 83

collect like terms'

7y+5y+3+8 = 83

12y + 11 = 83

12y = 83-11

12y = 72

y = 72/12

y = 6

b) Substitute y = 6 into RS and ST

Given RS = 7y+3

RS = 7(6)+3

RS = 42+3

RS = 45

For ST;

ST = 5y+8

ST = 5(6)+8

ST = 30+8

ST = 38
