Dovator [93]

Answer:

The plan A lasts 1.25 hours and plan B lasts 0.5 hours.

Step-by-step explanation:

Let the plan A takes x hours for training and plan B takes y hours for training.

So, from the conditions given we can write two different equations as

4x + 8y = 9 ............ (1) and

2x + 3y = 4 ............. (2)

Now. solving equations (1) and (2) we get,

8y - 6y = 9 - 8

⇒ 2y = 1

⇒ y = 0.5 hours.

Now, from equation (2) we get,

2x = 4 - 3 × 0.5 = 2.5

⇒ x = 1.25 hours.

Therefore, plan A lasts 1.25 hours and plan B lasts 0.5 hours. (Answer)

Answer:

<u>Given equations</u>: y = 3x² + x - 6; y = x - 4

So, Plug the value of value of y in other equation

  • 3x² + x - 6 = x - 4
  • 3x² + x - x - 6 + 4 = 0
  • 3x² - 2 = 0
  • 3x² = 2
  • x² = 2/3
  • x = √2/3
