Answer:
Step-by-step explanation:
eq. of circle is x²+y²+2gx+2fy+c=0
center=(-g,-k)
given eq. is x²+y²+4x-8y+11=0
comparing
2gx=4x
g=2
2fy=-8y
f=-4
center=(-2,4)
Answer:
x2−3x−2
Step-by-step explanation:
X= 3.124 bc ur using Pythagoras Theorem so a squared + b squared = c squared :)
Answer: -14
<u>Step-by-step explanation:</u>
f(x) = x - 3 --> x - 3
- g(x) = -(x + 11) --> <u>-x - 11 </u>
0x - 14 --> -14
NOTE: Your answer choices do not match up unless you are multiplying.
f(x) * g(x)
(x - 3)(x + 11)
= x(x + 11) - 3(x + 11)
= x² + 11x - 3x - 33
= x² + 8x - 33 (Option D)
