y =-3x + x + 9
Find y when x = 2
Substitute the value of x= 2 into the equation
y = -3(2) + 2 + 9
y = - 6 + 2 + 9
y = -4 + 9
y = 5
The answer is 5
 
        
             
        
        
        
Answer:
<h2>y = 54 ✅</h2>
Step-by-step explanation:
If the two numbers vary directly, we can use a proportion to find the missing value.
36/4 = y/6
4y = 216
Divide by 4
y = 54
Check
36/4 = 54/6
216 = 216 ✅
 
        
             
        
        
        
Direct variation is 
y=kx
subsitute
-6=-36k
diivde both sdies by -36
1/6=k
the equation is 
y=1/6x or B
        
             
        
        
        
Answer:
8.2 ft
Step-by-step explanation:
33.62 * 2 / 8.2 = 8.2 ft
 
        
                    
             
        
        
        
Area = r^2 x PI
 to find r take the square root of the area:
r = √100 = 10
The circumference of a circle is the diameter times PI.
 The diameter is 2 times r = 2 x 10 = 20
The circumference = 20PI m
The answer is C.
