(x - 7)² + (y - 3)² = 4 is your equation. 
        
             
        
        
        
Fist you need to substitute the value of R into the equation 
25-6(3)
Now you simply 
First multiple 6(3)
25-6(3)
25-18
Now solve!
25-18
7
The answer is 7

Answer:
x = 88.463° 
Step-by-step explanation:
We are given a trigonometric equation and we need to find out the value of x. The angle x lies between 0° and 360° . That is ,
 
 
<u>Given</u><u> </u><u>trigonometric</u><u> equation</u><u> </u><u>:</u><u>-</u><u> </u>
 
 
Subtracting 1 both sides , we have , 
 
 
Divide both sides by 5 , 
 
 
This equation can be written as , 
 
 
 
        
             
        
        
        
Answer:
Zachary is 9, Nicole is 8, and Jaycob is 27.
Step-by-step explanation:
x=Zachary
y=Nicole
z=Jaycob
x+y+z=44
x*3=z
x-1=y
However, for now, let's just assume that  x and y are actually the same, and that the answer is actually 45.
so, x*3=z, and y*3 also equals z.
This is so that technically, 45/5=x, because z accounts for 3, and both x and y account for 1 each, meaning altogether it should be 5 you should be dividing by. 45/5=9, so x=9. Now that we have that figured out, we can solve the rest easily. 9-1=8, so there's your y, and 9*3=27. 27+9=36, and 36+8=44.
