Answer:
C
Step-by-step explanation:
The vertex form of the equation of a circle is 
where (h,k) is the center of the circle and r is the radius. This means that for the circle with center (-3,1) and radius 5 substitute into the vertex form these values. Substitute h = -3, k= 1, and r = 5. The equation becomes 
. This simplifies to 
. The solution is C.
222,702 rounded to the nearest ten thousand would be 220,000
43.0810
Since the hundred thousandths is a 1 which is less than a 5, you have to round down.
Answer:
12 movies
Step-by-step explanation:
If you do not rent any vidoes you will be charged $45 no matter what, so...
Movies + 45 = total charge
each movie is 1.99 and you owe (total charge) $68.88
equation:
1.99x + 45 = 68.88
-45 -45 (subtract 45 from each side to keep equation balanced)
1.99x = 23.88 (now divide both sides by 1.99 to get x alone)
x = 12
you rented 12 movies
