Solve the Problem x27y23=1\frac { x ^ { 2 } } { 7 } - \frac { y ^ { 2 } } { 3 } = 1

Question 82

Multiple Choice

Solve the problem.
-The hyperbola x27y23=1\frac { x ^ { 2 } } { 7 } - \frac { y ^ { 2 } } { 3 } = 1 is shifted up 5 units and left 8 units. Find an equation for the new hyperbola and find the new vertices.


A) (x+8) 27(y5) 23=1\frac { ( x + 8 ) ^ { 2 } } { 7 } - \frac { ( y - 5 ) ^ { 2 } } { 3 } = 1 ; vertices: (8±7,5) ( - 8 \pm \sqrt { 7 } , 5 )
B) (x+5) 27(y8) 23=1\frac { ( x + 5 ) ^ { 2 } } { 7 } - \frac { ( y - 8 ) ^ { 2 } } { 3 } = 1 ; vertices: (8,5±3) ( - 8,5 \pm \sqrt { 3 } )
C) (x+8) 27(y5) 23=1\frac { ( x + 8 ) ^ { 2 } } { 7 } - \frac { ( y - 5 ) ^ { 2 } } { 3 } = 1 ; vertices: (8,5±3) ( - 8,5 \pm \sqrt { 3 } )
D) (x8) 27(y+5) 23=1;\frac { ( x - 8 ) ^ { 2 } } { 7 } - \frac { ( y + 5 ) ^ { 2 } } { 3 } = 1 ; vertices: (8±7,5) ( - 8 \pm \sqrt { 7 } , 5 )
