Quadratic formula since this trinomial is not factorable.
Answer:
(- 2, - 3 )
Step-by-step explanation:
Given the 2 equations
2x - 4y = 8 → (1)
y = x → (2)
Substitute y = x into (1)
2x - 4( x ) = 8
2x - 6x = 8
- 4x = 8 ( divide both sides by - 4 )
x = - 2
Substitute x = - 2 into (2) for corresponding value of y
y = × - 2 = - 3
Solution is (- 2, - 3 )

Answer:
- absolute error: 0.4 kg
- relative error: 6.1%
Step-by-step explanation:
The absolute error is the difference between the estimate and the actual weight:
7.0 kg -6.6 kg = 0.4 kg . . . . absolute error
__
The relative error is the ratio of the absolute error to the actual weight:
(0.4 kg)/(6.6 kg) × 100% = 6.060606...% ≈ 6.1% . . . . relative error
