Answer: D) x - 0.2x
Step-by-step explanation:
The hat has a regular price of x dollars.
This price is reduced by 20% so the relevant expression for the discount is; 20% * x or; 0.2x
The discounted price will be the price of the hat less the discount which means the formula will be;
= Price - discount
= x - 0.2x

Answer:
.
Step-by-step explanation:
In general, let 
denote the center of a given circle. Let 
denote the radius of that circle. The standard equation for that circle would be:
.
The circle in this question is centered at 
.
is the 
-coordinate of the center of this circle. 
.
is the 
-coordinate of the center of this circle. 
.
The radius of this circle is . Therefore, 
.
Hence, the standard equation for this circle would be:
.
