Answer: Person A generates 107.6 millions and person B generates 85.3 millions.
Step-by-step explanation:
Let 'x' millions be the amount generated by person A then the amount generated by person B be 'x-22.3' millions.
Since they both earn together $192.9 millions.
So according to the our assumptions we have,
Therefore, the amount generated by person A=107.6 millions
And the amount generated by person B= 192.9 millions - 107.6 millions
=85.3 millions

Answer:
Step-by-step explanation:
x^2 + 11y + y^2 -3x + 11 = 5x +23 - y
First put it into general form by setting the equation to zero and moving all variables to one side.
x^2 + 11y + y^2 -3x + 11 = 5x +23 - y
+y -5x -11 -11
x^2 + y^2 - 8x + 12y = 12
Then solve by completing the square
x^2 - 8x y^2 + 12y = 12
(x - )^2 + (y + )^2 =
Half of 8 is 4
Then square 4 to get 16
Therefore, we plug the 4 into the first parentheses
x^2 - 8x + 16 + y^2 + 12y =12 +16
(x - 4)^2 + (y + )^2 =
Half of 12 is 6
Squared, that would be 36
plug this into the second parentheses
x^2 - 8x + 16 + y^2 +12y + 36 = 12 + 16 + 36
(x - 4)^2 + (y + 6)^2 =
12 + 16 = 28 + 36 = 64
Therefore, the equation of the circle is: (x - 4)^2 + (y + 6)^2 = 64
Which is option D
Answer:
Set the denominator in 4x equal to 0 to find where the expression is undefined. x=0
The domain is all values of x that make the expression defined.
Interval Notation: (−∞,0)∪(0,∞)
Set-Builder Notation: {x|x≠0}
The range is the set of all valid y values. Use the graph to find the range.
Interval Notation: (−∞,4)∪(4,∞)
Set-Builder Notation: {y|y≠4}
Determine the domain and range.
Domain: (−∞,0)∪(0,∞), {x|x≠0}
Range: (−∞,4)∪(4,∞), {y|y≠4}
