Answer:
Center (-2 , 4)
Step-by-step explanation:
x^2 + 4x + y^2 - 8y = - 11
(x^2 + 4x + (4/2)^2 + (y^2 - 8y + (8/2)^2 ) = - 11 + 4 + 16
(x + 2)^2 + (y - 4)^2 = 9
Center (-2, 4)
Answer:
mean=12
Step-by-step explanation:
First, order the data like so.
5, 7, 12, 12, 16, 17, 17
Then add them all up.
It is a sum of 86.
Finally divide
86/7=12.2
Since 12.2 movies aren't possible, let's say the mean is 12
Answer:
4r(x)+2t(x)=42x-14
Step-by-step explanation:
4r(x)=32x+4
2t(x)=10x-18
4r(x)+2t(x)=32x+4+10x-18=42x-14
4x - 3y = 34
3x + 2y = 17
first equation should be multiplied by 2...second equation should be multiplied by 3
