Answer:
![x=\frac{-9}{7}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-9%7D%7B7%7D)
![y=\frac{-17}{7}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B-17%7D%7B7%7D)
Step-by-step explanation:
We have been given the equation:
![3x-2y-1=0](https://tex.z-dn.net/?f=3x-2y-1%3D0)
And ![y=5x+4](https://tex.z-dn.net/?f=y%3D5x%2B4)
Second equation can be rewritten as:
![5x-y=-4](https://tex.z-dn.net/?f=5x-y%3D-4)
We will solve the equations:
(1)
(2)
Multiply equation (1) by 5 and equation (2) by 3 we get:
(3)
(4)
Now, subtract (4) from (3) we get:
![-7y=17](https://tex.z-dn.net/?f=-7y%3D17)
![y=\frac{-17}{7}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B-17%7D%7B7%7D)
Now substitute
in equation (1) we get:
![3x-2{\frac{-17}{7}}=1](https://tex.z-dn.net/?f=3x-2%7B%5Cfrac%7B-17%7D%7B7%7D%7D%3D1)
![3x+\frac{34}{7}=1](https://tex.z-dn.net/?f=3x%2B%5Cfrac%7B34%7D%7B7%7D%3D1)
![21x=-27](https://tex.z-dn.net/?f=21x%3D-27)
![x=\frac[-27}{21}](https://tex.z-dn.net/?f=x%3D%5Cfrac%5B-27%7D%7B21%7D)
![x=\frac{-9}{7}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-9%7D%7B7%7D)
Answer:
$5750
Step-by-step explanation:
To solve this problem, you have to find the total profits for both the Black and Gold label. For the black label, the average profit is 1.5 per bottle and they sold 2000 bottles. To find the total profit, multiply 1.5 by 2000 to get 3000. Do the same to gold label to get 2750. Now add the profits 3000+2750=5750, which is the last answer choice.
I Agree because everything has to come with lines because every thing has to come in a shape with lines
Answer:
32% is the largest one
Step-by-step explanation:
please mark brainliest :) hope it helps :)
3+√x+19-√2x replace x by 6===> 3+√6+19-√2*6 = 3+√6+19-√12
Note that √12 = √2x6 = √2 x √6 ===>3+√6+19-(√2) x (√6)
=√6(1+√2)+22
