6 - 2x ≤ 4 => -2x ≤ -2 => x ≥ 1.

Subtract 6 from both sides: -3x ≤ -6. Then divide by -3 (reverse the inequality): x ≥ 2.

6 - 3x ≥ 0 => -3x ≥ -6 => x ≤ 2.

6x + 2 < 14 => 6x < 12 => x < 2.

7 - 3x > 1 => -3x > -6 => x < 2.

7 - 3x > 1 => -3x > -6 => x > 2.

7 - 3x < 1 => -3x < -6 => x > 2.

7 - x < 2 => -x < -5 => x > 5.

7x + 2 < 3x + 10 => 4x < 8 => x < 2.

7x - 4 < 2x + 11 => 5x < 15 => x < 3.

7x - 5 < 2x + 10 => 5x < 15 => x < 3.

8 - x > 3 => -x > -5 => x < 5.

x/3 + 2 > 1 => x/3 > -1 => x > -3.

x/3 - 2 > 1 => x/3 > 3 => x > 9.

x/3 - 2 ≤ 1 => x/3 ≤ 3 => x ≤ 9.

x/4 - 1 < 0 => x/4 < 1 => x < 4.

4x + 1 ≥ 3 => 4x ≥ 2 => x ≥ 0.5.

6 - x ≤ 2 => -x ≤ -4 => x ≥ 4.

Using the angle formula, we find the angle between the lines is 60 degrees.

Using the formula tan(θ) = |(m1 - m2) / (1 + m1*m2)|, we find that the angle is 60 degrees.

Length = 5 - 1 = 4, Width = 4 - 1 = 3. Area = Length * Width = 4 * 3 = 12.

Area = 1/2 * base * height => 24 = 1/2 * 8 * height => height = 6 cm.

Area = 1/2 * base * height => 30 = 1/2 * 10 * height => height = 6 units.

The argument of z = -1 - i is θ = tan^(-1)(-1/-1) = -3π/4.

Total sum = 5 * 18 = 90. New sum = 4 * 16 = 64. Excluded number = 90 - 64 = 26.

Total of five numbers = 5 * 18 = 90. Total of four numbers = 4 * 16 = 64. Removed number = 90 - 64 = 26.

The lines are parallel if h^2 = ab.

For the lines to be coincident, the discriminant must be equal to zero.

For the lines to be coincident, the discriminant of the quadratic must be zero.
