Answer:
Step-by-step explanation:
1.  Interchange x and y.  We get:  x = y^2 - 5
2. Solve for y:  y^2 = x + 5, so that y = ±√(x + 5)
 
        
             
        
        
        
Answer:
D
Step-by-step explanation:
I think it's D. Because you have that free shots give you 1 point so it is 1x or x , then you have two pointers which give you 2 points so it is 2y and you have three pointers which give you 3 points so it is 3z
 
        
             
        
        
        
Step-by-step explanation:
20 1/2 = (20×2 + 1)/2 = 41/2.
to create 1/6 of that we have to multiply it by 1/6 :
41/2 × 1/6 = 41/12 = 3 5/12
the rock weighed 3 5/12 lb.
 
        
             
        
        
        
The answer is 0.01. Plug this into a calculator or your phone to find the answer easily.
        
                    
             
        
        
        
Answer:
(0,20)
Step-by-step explanation:
1) we can represent the situation as coordinates
lets have # of texts be "x" variable
lets have bill be "y" as the y variable is always the dependant variable and the cost of the phone bill is dependant upon the number of texts so
y=mx+b-slope-intercept form
coordinates: (50,25) and (100,30)
slope: (30-25)/(100-50)
5/50=1/10
hence slope=1/10
y=1/10x+b
substitute in a coordinate pair into this equation
25=50*1/10+b
25=5+b
b=20
hence y intercept is (0,20)
