If `A=[[3,x],[y,5]]` and `A=A'` then

If A=[(3 ,x), (y ,5)] and A=A^T then (A)x=0,y=5 (B)x+y=5 (C)x=y (D)none of these

If 3x+5y =9 and 5x+3y=7, then find the value of x+y.

IF 3x +5Y = 9 and 5x + 3y =7 then find the value of x+y

Determine the nature of the quadrilateral formed by four lines 3x+4y-5=0,4x-3y-5=0;3x+4y-5=0 and 4x-3y+5=0 Find the equation of the circle insc quadrilateral inscribed and circumscribing this quadrilateral.

If 2 x + 3y = 12 and 3 x - 2y = 5 then

The area of the parallelogram whose sides are along the straight lines y=3x+5,y=3x+2,y=5x +4 and y=5x-1 is equals

The two curves y=3^x and y=5^x intersect at an angle

The area enclosed by y = 3x - 5, y = 0, x = 3 and x = 5 is
