Hello :
<span>note :
an equation of the
circle Center at the w(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : </span><span>x²+y²-16x+6y+53=0
(</span>x²-16x) +( y²+6y ) +53 = 0
(x² -2(8)x +8² - 8²) +(y² +2(3)x -3²+3² ) +53=0
(x² -2(8)x +8²) - 8² +(y² +2(3)x +3²)-3² +53=0
(x-8)² +( y+3)² = 20
the center is : w(8,-3) and ridus : r = <span>√20</span>
Answer:try B...
Step-by-step explanation:
i took the test and it wasn't C
The answer is 9
You divide 143 % 11 to get 13. 13 is the number they make an hour, so if you divide 117 % 13 you will get 9.
you change the y to have it y=3x+16 and same with the other one i think
