Answer:
x=ln(61)/ln(4)
Step-by-step explanation:
4^x+3=64
4^x=64-3
4^x=61
x=ln(61)/ln(4)
9-9 = 0 because there is no remainder
I believe it is D but it may be B
<u>Answer</u>
Center: (1,-12)
Radius: 5
<u>Work</u>
+-2x+24y+120=0 (Subtract 120 on both sides and rearrange)
-2x++24y=-120 (Then divide 2 by 2 and square it. Do the same for 24.)
-2x+1++24y+144=-120+1+144 (You have to add the same numbers on both sides)
(Simplify)
So you would put (1,-12); r=5
