Answer:
B. (x-9)^2 + (y + 7)^2 = 4
Step-by-step explanation:
The standard form of a circle is (x-h)^2 + (y-k)^2 = r^2. Hopefully you can memorize that, because it's very helpful in these problems!
(h,k) is our center, and r is our radius, so plug those values into the standard form:
(x - 9)^2 + (y + 7)2 = 2^2
2^2 = 4, so
<u>B. (x - 9)^2 + (y + 7)2 = 4 is our answer!</u>
Answer:
the answer is $7.78
Step-by-step explanation:
You multiply 6.5 times 1.88. Then you subtract that answer from 20.
Subtract 6 from both sides, you get 1/3x=-14
Now multiply both sides by there, hence x=-42
Answer:
x=-12
Step-by-step explanation:
32+2x=6+x+14
2x-x=6+14-32
x=-12
ST=6
TU=-12+14=2
SU=6+2=8
Answer:
3240°
Step-by-step explanation:
For a regular icosagon,
sum of interior angles measure=180(n-2)°
180(20-2)
180(18)=3240°
