3x3-27x=0<br> Solve by factoring a
Eddi Din [679]

After factoring 3x^3-27x=0 the solutions are x=0 , x=3, x= -3

Step-by-step explanation:

We need to solve by factoring:

3x^3-27x=0

Solving:

3x^3-27x=0

Taking 3x common:

3x(x^2-9)=0

Now using formula a^2-b^2=(a-b)(a+b)

3x((x)^2-(3)^2)=0\\3x(x-3)(x+3)=0

3x=0\,\,and\,\,x+3=0\,\,and\,\,x-3=0\\x=0\,\,and\,\,x=-3\,\,and\,\,x=3\\

So, After factoring 3x^3-27x=0 the solutions are x=0 , x=3, x= -3

25% of $160

= 0.25 * 160

= 40

$40 paid.

Balance owed = $160 - $40 = $120

Balance owed = $120

Does the table represent y as a function of x? Justify your answer.​
Otrada [13]

Answer:

  • No

Step-by-step explanation:

As per definition of the function, every x- value (input) has exactly one corresponding y-value (output)

<u>We can see on the table:</u>

  • x = 3.45 and y= 1.72
  • x = 3.45 and y = 3.36

Two same input values with different outputs.

So this not a function
