The equation 7y^(2) - 9x^(2) + 54x - 28y - 116 = 0 represents a _______

Solve (9xy + 7 xy + 9x ^(2)) + ( 8 + x ^(2) - xy - y ^(2) + 1).

The line 3x + 2y + 7 = 0 and 6x + 4y + 9 = 0 are "___________" to each other .

Add : 5x ^(2) - 3xy + 4y ^(2) - 9, 7y ^(2)+ 5xy - 2x ^(2) + 13

(x)/(2) - ( y )/(9) = 6, ( x) /( 7) + ( y ) /(3) = 5 .

For the lines 2x+5y =7 and 2x - 5y =9, which of the following statemetn is true ?

From an arbitrary point P on the circle x^2+y^2=9 , tangents are drawn to the circle x^2+y^2=1 , which meet x^2+y^2=9 at Aa n dB . The locus of the point of intersection of tangents at Aa n dB to the circle x^2+y^2=9 is x^2+y^2=((27)/7)^2 (b) x^2-y^2((27)/7)^2 y^2-x^2=((27)/7)^2 (d) none of these

Let the equation of circle is x^(2)+y^(2)=9 and the equation of the line is x+y=a AA a in N and makes the intercepts AB by the circle x^(2)+y^(2)=9. How many such intercepted portions are possible?
