F(x) = x2 − 2x How would I factor this?

2 answers:

3 0

The only way to factor an equation such as this is by pulling out the greatest common factor. When we look at what is the largest term in both of these, we discover both have an x, but nothing else. So, we need to extract an x out of each piece.

f(x) = x^2 - 2x

f(x) = x(x - 2)

This will give you the fully factored form for this equation.

f(x) = x^2 - 2x ← Factor out a common factor in each, which is a <em>x</em>

= x(x - 2)

And there you go!

How do you solve 9| x+8 | + 10 < 55 & how is it graphed

mafiozo [28]

Hello!

First, let's write the problem.
$9\left|x+8\right|+10\ \textless \ 55|x+8|+10\ \textless \ 55$
Subtract 10 from both sides.
$9\left|x+8\right|+10-10\ \textless \ 55-10$
$9\left|x+8\right|\ \textless \ 45$
Divide both sides by 9.
$\frac{9\left|x+8\right|}{9}\ \textless \ \frac{45}{9}$
$\left|x+8\right|\ \textless \ 5$
When we got absolute value, we are going to get two results.
$x+8\ \textless \ 5$
and
$x+8\ \textgreater \ -5$

Let's solve the first one,
$x+8\ \textless \ 5x+8\ \textless \ 5$
Subtract 8 from both sides.
$x+8-8\ \textless \ 5-8$
$x\ \textless \ -3x\ \textless \ -3$

Let's solve the second one.
$x+8\ \textgreater \ -5$
Subtract 8 from both sides.
$x+8-8\ \textgreater \ -5-8$
$x\ \textgreater \ -13x\ \textgreater \ -13$

Let's combine the ranges.
$-13\ \textless \ x\ \textless \ -3$

The attachment shows how would you graph it.
You can feel free to let me know if you have any questions regarding this.
Thanks!

SOVA2 [1]

Answer:

576 ways

Step-by-step explanation:

There are 4 choices for the column of pawn in the 1st row

There are 3 choices for the column of pawn in the 2nd row,

There are 2 choices for the column of pawn in the 3rd row, and

There is 1 choice for the column of the pawn in the 4th row

Which gives a total of 4! = 24

Also, the pawns are distinct, so there are 4! ways to place them in these chosen positions;

4! = 24

So, there are 24 * 24 possible ways

= 576 ways

The population of the world in 1987 was 5 billion and the annual growth rate was estimated at 2 percent per year. Assuming that

Vinvika [58]

Answer:

Population in 1998 year = 6.22 billion

Step-by-step explanation:

Given:-

- The population in year 1987, Po = 5 billion

- Growth rate, r = 2%

- World population follows an exponential growth model

Find:-

The projected world population in 1998.

Solution:-

- The exponential growth model is mathematically expressed as:

Population in x year = Po* ( 1 + r/100)^( x - xo )

Where, xo: The base year.

- Plug in the values and solve for the projected population in year 1998:

Population in 1998 year = 5,000,000,000* ( 1 + 2/100)^( 1998 - 1987 )

Population in 1998 year = 5,000,000,000* ( 1 + 0.02)^( 11 )

= 5,000,000,000* ( 1.02 )^( 11 )

= 6.22 billion
