Determine the appropriate rotation formulas to use so that the new equation contains no xy-term. - 3x2+5xy+3y2−8x+8y=03 x ^ { 2 } + 5 x y + 3 y ^ { 2 } - 8 x + 8 y = 0


A) x=12x′−32y′x = \frac { 1 } { 2 } x ^ { \prime } - \frac { \sqrt { 3 } } { 2 } y ^ { \prime } and y=32x′+12y′y = \frac { \sqrt { 3 } } { 2 } x ^ { \prime } + \frac { 1 } { 2 } y ^ { \prime }
B) x=2+22x′−2−22y′x = \frac { \sqrt { 2 + \sqrt { 2 } } } { 2 } x ^ { \prime } - \frac { \sqrt { 2 - \sqrt { 2 } } } { 2 } y ^ { \prime } and y=2−22x′+2+22y′y = \frac { \sqrt { 2 - \sqrt { 2 } } } { 2 } x ^ { \prime } + \frac { \sqrt { 2 + \sqrt { 2 } } } { 2 } y ^ { \prime }
C) x=22(x′−y′) x = \frac { \sqrt { 2 } } { 2 } \left( x ^ { \prime } - y ^ { \prime } \right) and y=22(x′+y′) y = \frac { \sqrt { 2 } } { 2 } \left( x ^ { \prime } + y ^ { \prime } \right)
D) x=−y′x = - y ^ { \prime } and y=x′y = x ^ { \prime }

Match the graph to its equation. - Match the graph to its equation. - A) \frac { y ^ { 2 } } { 16 } + \frac { x ^ { 2 } } { 9 } = 1 B) \frac { x ^ { 2 } } { 9 } - \frac { y ^ { 2 } } { 16 } = 1 C) \frac { y ^ { 2 } } { 16 } - \frac { x ^ { 2 } } { 9 } = 1 D) \frac { x ^ { 2 } } { 16 } + \frac { y ^ { 2 } } { 9 } = 1


A) y216+x29=1\frac { y ^ { 2 } } { 16 } + \frac { x ^ { 2 } } { 9 } = 1

B) x29−y216=1\frac { x ^ { 2 } } { 9 } - \frac { y ^ { 2 } } { 16 } = 1

C) y216−x29=1\frac { y ^ { 2 } } { 16 } - \frac { x ^ { 2 } } { 9 } = 1

D) x216+y29=1\frac { x ^ { 2 } } { 16 } + \frac { y ^ { 2 } } { 9 } = 1
