Answer:
system of equations
Step-by-step explanation:
You can eliminate one of the variable terms in a <u>system of equations</u> by adding or subtracting another equation.
 
        
             
        
        
        
Substitute each value of x in y=2x-3
so,
first box (-2)
y= 2(-2)-3
y= -4-3
y= -7
second box (0)
y= 2(0)-3
y= 0-3
y= -3
third box (3)
y=2(3)-3
y=6-3
y=3
        
                    
             
        
        
        
Answer:
 r = π C , C = 12 − x , t h e n r = π ( 12 − x ) = 12 π − π x
Step-by-step explanation:
So cutting the wire of 12 m in length into two pieces, x and 12-x. The x side will be made into the square so that the square has sides x/4 and an area of (x/4)^2. This means the length of the wire 12-x will be the circumference of the circle. So if: r = π C , C = 12 − x , t h e n r = π ( 12 − x ) = 12 π − π x i hope this is correct 
 
        
             
        
        
        
I think b because all the other lines are the same length and b lines aren’t
