How do i graph <br> x–3y=–9<br> 2x–3y=–6

Katen [24]

Right now the equations are in standard form, which is ax+by=c. You need to put them in the form y=x and then divide the equations by 3 since y itself is being multiplied by 3. And then graph them as you normally would

Hope this helps!

The combined height of one fir tree and one pine tree is 212121 meters. The height of 444 fir trees stacked on top of each other

inn [45]

Answer: The height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.

Step-by-step explanation:

Let x= height of each fir tree, y = height of each pine tree.

As per given, we have

x+y = 21 (i)

4x=y+24 (ii)

From (ii),

$4x-y=24$ (iii)

Add (i) and (iii), we get

$5x=45\\\\\Rightarrow\ x=\dfrac{45}{5}\\\\\Rightarrow\ x=9$

Put value of x in (i), we get

$9+y=21\Rightarrow y=12$

Hence, the height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.

Answer:

The number of combinations will she have to analyze is 10.

Step-by-step explanation:

We know that Boeing currently produces five models of airplanes for commercial sale. The airline that Lauren works for is rapidly expanding and would like to purchase three airplanes of different models to service various routes. We calculate the number of combinations will she have to analyze.

$C^5_3=\frac{5!}{3!(5-3)!}=\frac{5\cdot 4\cdot 3!}{3!\cdot 2\cdot 1}=10$

The number of combinations will she have to analyze is 10.
