Answer:
Step-by-step explanation:
x^2 - 22x = 10
Next step is to complete the square on the left hand side of the equation and it would be balanced by adding the same number to the right side of the equation. It becomes
x^2 - 22x + (22/2)^2 = 10 + (22/2)^2
x^2 - 22x + (11)^2 = 10 + (11)^2
x^2 - 22x + (11)^2 = 10 + 121
x^2 - 22x + (11)^2 = 131
x^2 - 22x + 121^2 = 131
(x - 11)^2 = 131
Taking square root of both the left hand side and the right hand side of the equation, it becomes
x - 11 = ±√131
x - 11 = ±11.45
Adding 11 to the left hand side and the right hand side of the equation, it becomes
x - 11 + 11 = ±11.45 + 11
x = 11.45 + 11 or x = -11.45 + 11
x = 22.45 or x = - 0.45
The midpoint is the average of the endpoints.
((-11+i) + (-4+4i))/2 = -15/2 +5/2i
Answer:
it's = 0
you have to use the steps of maths
Answer: No its not a function.
Step-by-step explanation: Its not a function because the y coordinate has the same x coordinates. This fails the vertical line test.
Answer:
x=3, y=4. (3, 4).
Step-by-step explanation:
x+y=7
x+2y=11
--------------
-x-y=-7
x+2y=11
--------------
y=4
x+4=7
x=7-4
x=3
