tolong bantu dong nanti aku give saldo shopeepay (2) ,ga usah pake cara kak
Jawaban:
P(-4,-4)
a= -4
b=-4
[tex]r = |b | \\ | - 4| \\ = 4[/tex]
(x-a)² +(y-b)²=r²
(x-(-4))²+(y-(-4))²= 4²
(x+4)² +(y+4)² = 16
x²+8x+16+y²+8y+16=16
x²+y²+8x+8y+16+16=16
x²+y²+8x+8y+32=16
x²+y²+8x+8y+32-16 =0
x²+y²+8x+8y+16=0
jawabannya A
