Answer:

y = -2/3x -6

Step-by-step explanation:

-2x -3y = 18

+2x        +2x

-3y = 2x + 18

-3y/-3 = 2x/-3 + 18/-3

y = -2/3x -6

Identify the expression and the value equivalent to 4 times 3 cubed
MrRa [10]

Answer:

4 \times 3^{3}\\\\4\times3 \times3\times3\\\\108

Step-by-step explanation:

Four times three cubed

Given the statement, times means multiplication.

four times three

4        x         3

It says three cubed, where cubed means raised to 3. So that means we right an exponent, and the exponent is 3.

4 x 3³

When we have an exponent, that tells you how many times you will multiply it by itself. So since the exponent is 3, we multiply 3 by itself 3 times.

3³ = 3 x 3 x 3

So 4 x 3³ = 4 x 3 x 3 x 3

Lastly, if we get the product your result will be 108.

4 x 3 x 3 x 3

=4 x 27

= 108

If the walls are 9' high, how much paint would I need to buy to paint the walls of all three bedrooms?
ludmilkaskok [199]

Answer:

The required paint for a total of 1.404\ ft^{2} is approximate 6 gallons

Step-by-step explanation:

we know that

To find how much paint would I need to buy to paint the walls of all three bedrooms, calculate the area of all three bedrooms

<em>Master Bedroom</em>

The area is equal to

A1=(16+16+12+2+18)*9=576\ ft^{2}

<em>2 Bedroom</em>

The area is equal to

A2=(12+14+10+10)*9=414\ ft^{2}

<em>3 Bedroom</em>

The area is equal to

A3=(10+10+14+10+2)*9=414\ ft^{2}

The total area is equal to

A=A1+A2+A3

A=576+414+414=1.404\ ft^{2}

Approximate one gallon of paint covers 250 square feet

so

1.404/250=5.6\ gal

For the given function, find the vertical and horizontal asymptote(s) (if there are any). f(x) = the quantity x squared plus thr
vodka [1.7K]
The vertical asymptotes are:  "x = 3" and "x = -3" .
__________________________________________
The horizontal asymptote is:  "y = 2"  .  
___________________________________________
Explanation:
___________________________________________

f(x) = \frac{x^{2}+ 3}{ x^{2} - 9} ;

We know that "(x² − 9) ≠ 0 ; since we cannot divide by "0" ; so the "denominator" in the fraction cannot be "0" ;

 since: 9 − 9 = 0 ;  "x² " cannot equal 9.

So, what values for "x" exist when "x = 9" ?

 x² = 9 ;  

Take the square root of EACH SIDE of the equation ; to isolate "x" on one side of the <span>equation ; and</span> to solve for "x" ;

  √(x²) = √9 ;

     x = ± 3 
<span>__________________________________________
So; the vertical asymptotes are:  "x = 3" and "x = -3" .
__________________________________________
The horizontal asymptote is:  "y = 2"  .  
__________________________________________
(since:  We have: </span>f(x) = \frac{x^{2}+ 3}{ x^{2} - 9} ;

The "x² / x² " as the highest degree polymonials; both with "implied" coefficients of "1" ; and both raised to the same exponential power of "2".
