Answer: 60000

Step-by-step explanation:

The ten thousands place is the 5th digit from the right. Because the digit in the thousands place is less than 5, round down to 60000.

Divide (-3x^2 - 9x) ÷ (x + 3) please explain/show work! <33

Stolb23 [73]

Step-by-step explanation:

 $( - 3 {x}^{2} - 9x) \div (x + 3)$ 

This is the original equation so you will open the brackets.

 $- 3 {x}^{2} - 9x \div x + 3$ 

The x will cross the division sign making it times x.

 $3 {x}^{2} - 9x \times x = 3$ 

So you will proceed to multiply the 9x by x making it;

 $3 {x}^{2} - 9 {x}^{2} = 3$ 

So you will subtract 9x² from 3x² which won't be possible so it will be negative.

 $- 6 {x}^{2} = 3$ 

Then you will square root both sides making it;

 $- \sqrt{6 {x}^{2} } = \sqrt{3}$ 

So the ² will cancel the √ leaving 

-6x=√3

-6x=1.73(Divide both sides by -6)

x=0.288

That's the final answer.

makvit [3.9K]

Answer:

Is there answer options because if not then it would possibly be y = 45x + 540 or it could be 45x = 540 or it could be 45x/540 so it can be any of those :)

What is the growth factor associated with the following growth rate: 30% decrease

fenix001 [56]

Given:

Growth rate = 30% decrease

To find:

The growth factor associated with the given growth rate.

Solution:

The general exponential function is:

$y=a(1+r)^x$

$y=a(b)^x$

Where, a is the initial value, r is the growth rate in decimal and $b=1+r$ is the growth factor.

It is given that the growth rate is 30% decrease. So,

$r=-30\%$

$r=-\dfrac{30}{100}$

$r=-0.3$

Now,

$b=1+r$

$b=1+(-0.3)$

$b=1-0.3$

$b=0.7$

Therefore, the growth factor is 0.7.
