Answer:
This a circle centered at the point
, and of radius "3" as it is shown in the attached image.
Step-by-step explanation:
Recall that the standard formula for a circle of radius "R", and centered at the point
is given by:

Therefore, in our case, by looking at the standard equation they give us, we extract the following info:
1)
since the radius must be a positive number and (
) is not a viable answer.
2)
for (
) to equal 
3)
for (
) to equal 
Therefore, we are in the presence of a circle centered at the point
, and of radius "3". That is what we draw as seen in the attached image.

Answer:
95$!
Step-by-step explanation:
475 x 20% = 95
Answer:
0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8x+4(4x+3)=4(6x+4)−4
8x+(4)(4x)+(4)(3)=(4)(6x)+(4)(4)+−4(Distribute)
8x+16x+12=24x+16+−4
(8x+16x)+(12)=(24x)+(16+−4)(Combine Like Terms)
24x+12=24x+12
24x+12=24x+12
Step 2: Subtract 24x from both sides.
24x+12−24x=24x+12−24x
12=12
Step 3: Subtract 12 from both sides.
12−12=12−12
0=0
