Answer:
y^6/x^2
Step-by-step explanation:
(y^3/2x^-1/2)^4= y^(4*3/2)x^(-1/2*4)=y^6x^-2= y^6/x^2
Answer:
x = - 1 ± i 
Step-by-step explanation:
Given
3x² = - 12 - 6x ( add 6x to both sides )
3x² + 6x = - 12 ( divide through by 3 )
x² + 2x = - 4
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1 = - 4 + 1
(x + 1)² = - 3 ( take the square root of both sides )
x + 1 = ±
= ± i
( subtract 1 from both sides )
x = - 1 ± i 
Answer:
A. A tennis tournament in which after each round, half the players are eliminated.
Step-by-step explanation:
Area of parallelogram: lw = 9(5)=45m
Area of triangle: 1/2bh = 1/2(9)(8) = 36m
So total area = 45+36=81m
The answer is (-1,1)
The solution is the point where the two lines cross each other
Hope this helps
