Answer:

x=-2 \quad and \quad y=7.

Step-by-step explanation:

\left\{\begin{matrix} y=-x+5 \\  x-y=-9\end{matrix}\right.\\\\\Rightarrow \left\{\begin{matrix} x+y=5 & (1)\\  x-y=-9 & (2)\end{matrix}\right.\\(1) + (2) \Rightarrow 2x=-4 \Rightarrow x=-4:2=-2\\Replace \quad x=-2\quad in \quad(1) \Rightarrow y=5-(-2)=7\\Therefore, \\x=-2 \quad and \quad y=7.

Q4. after landing, an aircraft is delayed in reaching its parking stand.
Natalija [7]

The workout cost of a delay of 8 minutes is 7228 p.

<h3>What is Workout cost?</h3>

The strike price of an option is a fixed price at which the owner of the option can buy, or sell, the underlying security or commodity.

Here, 1 liter fuel = 0.82 kg.

       Aircraft use per minute 11.4 kg fuel = 11.4 / 0.82 liters = 13.90 liters.

       Cost of 1 liter fuel = 65p.

       Delay in reaching parking stand = 8 minutes

        Fuel consumption in 8 minutes = 8 X 13.90 = 111.2 liters

        Total workout cost of delay = Cost per liter X total consumed fuel

                                                       = 65 X 111.2

                                                       = 7228 p.

Thus, the workout cost of a delay of 8 minutes is 7228 p.
