Directions(1-5): Find the relation between x and y and choose a correct option.

  1. I. 5x^2 – 29x + 36 = 0
    II. 10y^2 – 3y – 27 = 0

    y>x
    x=y or relation cannot be established.
    x>y
    y>=x
    x>=y
    Option E
    I. 5x^2 – 29x + 36 = 0
    => 5x^2 – 20x – 9x + 36 = 0
    => 5x(x-4) – 9(x-4) = 0
    => (x-4)(5x-9) = 0
    => x = 4 , 9/5
    II. 10y^2 – 3y – 27 = 0
    => 10y^2 – 18y + 15y – 27 = 0
    > 2y (5y-9) + 3(5y – 9) = 0
    => y = 9/5 , -3/2
    x>=y

     

  2. I. 7x^2 – 54x + 99 =0
    II. 4y^2 – 16y + 15 = 0

    x>y
    x>=y
    y>=x
    y>x
    x=y or relation cannot be established.
    Option A
    I. 7x^2 – 54x + 99 =0
    => 7x^2 – 33x – 21x + 99 =0
    => x(7x – 33) – 3(7x – 33) = 0
    => x = 333/7 , 3
    II. 4y^2 – 16y + 15 = 0
    => 4y^2 – 10y – 6y + 15 = 0
    => 2y (2y – 5) – 3(2y-5) = 0
    => y = 5/2 , 3/2
    x>y

     

  3. I. x^2 – 6x – 91 = 0
    II. y^2 – 32y + 247 = 0

    y>=x
    x>y
    x>=y
    x=y or relation cannot be established.
    y>x
    Option A
    I. x^2 – 6x – 91 = 0
    => x^2 – 13x + 7x – 91 = 0
    => x = 13, -7
    II. y^2 – 32y + 247 = 0
    => y^2 – 19y -13y + 247 = 0
    => y = 19, 13
    x ≤ y

     

  4. I. x^2 + 5x – 14 = 0
    II. y^2 + 24y + 128 = 0

    x=y or relation cannot be established.
    y>x
    y>=x
    x>=y
    x>y
    Option E
    I.x^2 + 5x – 14 = 0
    => x^2 + 7x – 2x – 14 = 0
    => x = -7, 2
    II. y^2 + 24y + 128 = 0
    => y^2 + 16y + 8y + 128 = 0
    => y = -16, -8
    x > y

     

  5. I. x^2 + x – 30 = 0
    II. y^2 – 11y + 30 = 0

    x=y or relation cannot be established.
    x>=y
    y>x
    x>y
    y>=x
    Option E
    I. x^2 + x – 30 = 0
    => x^2 + 6x – 5x – 30 = 0
    => x = – 6, 5
    II. y^2 – 11y + 30 = 0
    => y^2 – 5y – 6y + 30 = 0
    => y = 5, 6
    x ≤ y
