**6)**

- 2x
^{2 }+ 9x+9 = 0 - 15y
^{2 }+16y+4 = 0

Answer:

I. 2x^{2 }+ 9x+9 = 0

x = -6/2, -3/2 = -3, -1.5

II. 15y^{2 }+16y+4 = 0

y = -6/15, -10/15 = -0.4, ย -0.66

x < y.

7)

- 2x
^{3}= โ256 - 2y
^{2 }+ 9y +10 = 0

Answer:

I. 2x^{3 }= 16

x^{3ย }= 8

x = 2

II. y = 4/2, 5/2 = 2, 2.5

X โฅ Y.

8)

- 6x
^{2 }– 11x + 4 = 0 - 3y
^{2 }– 5y +2 = 0

Answer:

I. 6x^{2 }– 11x + 4 = 0

6 x^{2 }โ 8x โ 3x + 4 = 0

2x(3x-4)- (3x – 4) = 0

x = 0.5, 1.33

II. 3y^{2 }– 5y +2 = 0

3y^{2 }โ 3y โ 2y + 2 = 0

y = 1, 0.666

The relationship cannot be determined between X and Y.

9)

- 3x
^{2 }+ 11x+10 = 0 - 2y
^{2 }+ 11y +14 = 0

Answer:

I. 3x^{2 }+ 11x+10 = 0

x = -5/3, -6/3 = -1.66, -2

II. 2y^{2 }+ 11y +14 = 0

y = -8/2, -3/2 = -4, -1.5

The relationship cannot be determined between X and Y.

10)

- 12x
^{2 }+ 11x+2 = 0 - 12y
^{2 }+ 7y +1 = 0

Answer:

I. 12x^{2 }+ 11x+2 = 0

x = -8/12, -3/12 = -0.66, -0.25

II. 12y^{2 }+ 7y +1 = 0

y = -3/12, -4/12 = -0.25, -0.33

The relationship cannot be determined between X and Y.

11)

- 21x
^{2 }+ 10x+1 = 0 - 24y
^{2 }+ 26y +5 = 0

Answer:

I. 21x^{2 }+ 10x+1 = 0

x = -7/21, -3/21 = -0.33, -0.1428

II. 24y^{2 }+ 26y +5 = 0

y = -0.83, -0.25

The relationship cannot be determined between X and Y.
