Salutations!

<span>How can you use a number line to represent the subtraction between two integers?

A number line is a representation to help find your sums. To represent the subtraction between two integers ----- you need to just jump backwards; move towards your left on the number line.

Hope I helped :D</span>

Find all the real zeros of <br><br> f(x)=3x^3-9x^2+3x-9 <br><br><br> Can someone help me please
vaieri [72.5K]

Answer:

x=0,3

Step-by-step explanation:

start by dividing every term by 3

x^3-3x^2+x-3

group into 2 terms

(x^3-3x^2)+(x-3)

simplify as much as you can

x^2(x-3)+(x-3)

combine terms

(x^2)(x-3)

x=3, 0

What proportion of the first 10,000 natural numbers contain a 3
Sergeeva-Olga [200]
In the first 10 -> 10 - 9 = 1 (contain a 3).
In the first 100 -> 100 - 9 * 9 = 19 (contain a 3).
In the first 10^n -> 10^n - 9^n  (contain a 3).


&#10;&#10;So for 10^4 -> 10^4 - 9^4 = 10.000 - 6.561 = 3.439 &#10;

<u>The answer is 3.439 numbers contain a 3 in the first 10.000</u>
