Answer:
Step-by-step explanation:
hello :
x2 plus y2-6x plus 2y equals 6 means :
x²+y²-6x+2y =6
(x²-6x)+(y²+2y)=6
(x²-6x+9 -9 )+(y²+2y+1-1) = 6
(x-3)²-9 +(y+1)²-1 = 6
(x-3)²+(y+1)² = 4²
standard form when the center is : (3;-1) and length of the radius is :4
Answer:
114
Step-by-step explanation:
Ratio of red marbles to black marbles is 19:1. (Data from 3rd sentence)
19+1= 20
20 units= 120 (Data from 1st sentence)
1 unit= 120/20= 6
19 units= 120-6= 114 (Values solved in working above)
Ans: There are 114 red marbles.
i hope i cleared your doubt
Where are the graphs to match the inequalities with?
Answer:
$8518.40
Step-by-step explanation:
FV = PV(1+r)^n
FV = future value
PV = present value
r = rate
n = # of years
Value in 2 yrs = 11,000 x (1 - 0.12)^2 = 8518.4
