The dogs are going to be labeled x. This problem can be represented by the equation 4x+x=30, because there are 30 dogs total and 4x is the boxers and x is the spaniels. We then solve for x, 5x=30, x=6. Then we can plug this x value into the equations for boxers and spaniels, finding that there are 24 boxers and 6 spaniels.

The revenue from manufacturing and selling x units of toaster ovens is given by:

nexus9112 [7]

Answer:

$248,000.

Step-by-step explanation:

We have been given that the revenue from manufacturing and selling x units of toaster ovens is given by $R(x)=-0.3x^2+200x-82,000$ .

To find the amount of revenue earned from selling 3,000 toaster, we will substitute $x=3,000$ in the given formula as:

$R(3,000)=-0.03(3,000)^2+200(3,000)-82,000$

$R(3,000)=-0.03*9,000000+600,000-82,000$

$R(3,000)=-270,000+518,000$

$R(3,000)=248,000$

Therefore, the company should expect revenue of $248,000 from selling 3,000 toaster ovens.

Y = 3x + 15<br> 3x + 3y = 9

Zina [86]

Answer:

$\Large\boxed{x=-3}$ $\Large\boxed{y=6}$

Step-by-step explanation:

<u>Given the system of equations</u>

$1)~y=3x+15$

$2)~3x+3y=9$

<u>Divide 3 on both sides of the 2) equation</u>

$3x+3y=9$

$3x\div3+3y\div3=9\div3$

$x+y=3$

<u>Current system</u>

$1)~y=3x+15$

$2)~x+y=3$

<u>Substitute 1) equation into the 2) equation</u>

$x+(3x+15)=3$

<u>Combine like terms</u>

$x+3x+15=3$

$4x+15=3$

<u>Subtract 15 on both sides</u>

$4x+15-15=3-15$

$4x=-12$

<u>Divide 4 on both sides</u>

$4x\div4=-12\div4$

$\Large\boxed{x=-3}$

<u>Substitute the x value into one of the equations to find the y value</u>

$y=3x+15$

$y=3(-3)+15$

$y=-9+15$

$\Large\boxed{y=6}$

Hope this helps!! :)

A plane flies from Houston to nyc in 4hours the distance it travelled was 1627miles what was the average speed of the plane

Tamiku [17]

406.75 since the equation for speed is distance over time so you would do 1627 divided by 4

Exercises Solve each inequality. Graph the solution set on a number line. 3x – 4 < 17

Nonamiya [84]

Answer:

x <7

Step-by-step explanation:

3x – 4 < 17

Add 4 to each side

3x – 4+4 < 17+4

3x < 21

Divide each side by 3

3x/3 < 21/3
