Answer: (-2, 5/3)
explanation: since you are given x = -2, just plug that into the equation and solve.
        
             
        
        
        
7+3x-12x=3x+1
We will first make all the numbers which have x in go to the left.
So 7+3x-12x-3x, we make the 3x negative since to make it move it needs to change.
Then we will make all the sevens go to the right, so 3x-12x-3x=1-7.
So now it is much easier to figure out.
-12x=-6
        
             
        
        
        
Answer:
7.5 m
Step-by-step explanation:
circumference = 360/72 × 3π = 15π
so the radius of the circle =
15π / 2π = 7.5 m
 
        
             
        
        
        
Answer:
-27
Step-by-step explanation:
substitute x for 5

multiply -5 and 5

subtract 2 from -25

 
        
                    
             
        
        
        
Anything without a variable in front.
In other words, the constants are -3.7 and 1/3
