X= the number

7(x+9) = 84

7x+63 = 84

7x = 21

x=3

     Check:

    7(3+9) =84

      7 x12 = 84

Which are the solutions of x2 = –7x – 8?
Yanka [14]
You can start by rewriting the equation so that the right side equals zero. Add -7x and 8 to both sides.

x^2+7x+8=0

You can now use the quadratic equation (below), where a=1, b=7, and c=8, to find solutions. Plug in these values for a, b, and c into the equation and simplify.

\frac{-b \pm \sqrt{b^2-4(ac)}} {2a}
\frac{-7 \pm \sqrt{7^2-4(1 \times 8)}} {2 \times 1}
\frac{-7 \pm \sqrt{49-32}} {2}
\frac{-7 \pm \sqrt{17}} {2}

The final answer is the combination of both solutions.
x=\frac{-7}{2} \pm \frac{\sqrt{17}} {2} \approx -3.5 \pm 2.06.

Or approximately...
x=(-3.5-2.06) \approx -5.56, (-3.5+2.06) \approx-1.44

An airline reports that 85% of its flights arrive on time. To find the probability that its next four flights into LaGuardia Air
olga55 [171]

Answer:

The answer is "no".

Step-by-step explanation:

No, because the probability besides simultaneous flights to arrive on time are not self-sufficient for every flight (when the first flight was late, therefore the probabilities during the next flight were significantly greater), because then the standard multiplication principle would be used for explanatory variables.
