0.84(20)=$16.80
700/100=7 
7(1.02)=$7.14
$7.14+16.80=$23.94 in total
        
             
        
        
        
Answer:
Reflection over y-axis
Step-by-step explanation:
We know that with a reflection of the x-axis, we flip the value of the y value
But since the y-values in Q3 and Q4 are both negative, we know that can't be the case
So it has to be a reflection over the y-axis where the x-values are flipped
Hope this helps
 
        
             
        
        
        
The general equation given is x^2 - 4x + y^2 = -3. Transform this to an equation of a circle of the form x^2 + y^2 = r^2.
Use completing the square method:
x^2 - 4x + 4 + y^2 = -3 + 4
(x - 2)^2 + y^2 = 1
the center of the circle is (2,0) and r = 1
To check if it intersects the y axis, find the value of the x-intercept. 
        
             
        
        
        
Angle 2 and angle 4 are vertical angles which makes them congruent
