First you combine 8x and -2x which is -6x
and 5+-1=4   
y=-6x+4
        
             
        
        
        
Answer:
2√10
Step-by-step explanation:
Given the coordinates (-6, 2) and (0,0)
We are to find the distance between the coordinates. Using the distance formula;
d = √(x2-x1)²+(y2-y1)²
d = √(0-2)²+(0+6)²
d = √(-2)²+(6)²
d = √4+36
d = √40
d = √4*10
d = 2√10
Hence the required distance is 2√10
 
        
             
        
        
        
1F=1/3Y
(1F)^2=(1/3Y)^2
F^2=1/9Y^2
------------------------
13F x 22F = 286F^2
-------------------------
286F^2 = 286 x 1/9 x Y^2
286F^2 = 286/9 Y^2
-------------------------
286/9 x $19.50 = $619.67
------------------------
Answer:
$619.67
        
             
        
        
        
Answer:
Option A is correct.
Step-by-step explanation:
We are given:

We need to find the value of a.
The LCM of (2+i) and (3+i)  is (2+i)(3+i)

Now rationalize the denominator by multiplying by 5-5i/5-5i

We are given 

Now after solving we have:

So value of a = 1/10 and value of b = -1/10
So, Option A is correct.
 
        
             
        
        
        
Answer:
y = 5z - x
Step-by-step explanation:
Given
z =  ( multiply both sides by 5 to clear the fraction )
 ( multiply both sides by 5 to clear the fraction )
5z = x + y ( subtract x from both sides )
5z - x = y
