Answer:
What is the constant variation of Y =- 2 3x?
The constant of variation, k , is 23 .
Step-by-step explanation:
When x is zero in a direct variation equation y will also be zero. That means that the y-intercept of all direct variation equations is always zero.
 
        
             
        
        
        
Subtracting 3x^4+9x^3+3x^2 from the divided and bringing down 13x.
 
        
                    
             
        
        
        
Answer:
no Solution
Step-by-step explanation:
-12x-12y=4\\ 3x+3y=0 
12x-12y=4
add 12y to both sides
12x-12y+12y=4+12y
divid both sides by -12
\frac{-12x}{-12}=\frac{4}{-12}+\frac{12y}{-12}
simplfy 
x=-\frac{1+3y}{3}
\mathrm{Substitute\:}x=-\frac{1+3y}{3}
\begin{bmatrix}3\left(-\frac{1+3y}{3}\right)+3y=0\end{bmatrix}
\begin{bmatrix}-1=0\end{bmatrix}
 
        
             
        
        
        
You have 180 tablets right? You also have to take it three times a day.
180 pills /3 pills a day = <u>60 days</u>

Answer:
1st: 22, 2nd: 27, 3rd: 88
Step-by-step explanation:
Make an equation 
If she recieved x calls the 1st evening, then the 2nd evening she recieved x+5, and the 3rd evening she recieved 4x. 
x+x+5+4x=137 
Combine like terms 
6x+5=137
Subtract 5 from both sides 
6x=132
Divide by 6 on both sides 
x=22 
First: 
22 calls
Second: 
x+5
22+5
27 calls
Third: 
4x
4*22
88 calls 
Hope this helps!
