Answer:
42
Step-by-step explanation:
 √2x-3-3=6
√2x-3=6+3
√2x-3=9
2x-3=9^2
2x=81+3
X=84/2
X=42
So value of X is 42
 
        
             
        
        
        
Answer:
since output value is paried with input value teh relationship IS a function
Step-by-step explanation:
 
        
             
        
        
        
So point slope form is y=mx+b where m=slope and b=y intercept so 
in (x,y) form
one solution is x=1 and y=3, also slope is 2 so 
m=2 
subsitute
3=2(1)+b
3=2+b
subtract 2
1=b
equation is 
y=2x+1
tricky answers so simplify them
A: y-1=2(x-3)
distribute
y-1=2x-6
add 1
y=2x-5
not the answer
B: y-3=2(x-1)
distribute
y-3=2x-2
add 3
y=2x+1
correct
the answer is B
