Answer:
x = -1 +/-2i
Step-by-step explanation:
Write the equation in standard form to find the roots, also known as the solutions, zeros, or x-intercepts, of the quadratic.
x² + 2x + 5 = 0
Use the quadratic formula by substituting a= 1, b = 2 and c = 5.

Answer:
Step-by-step explanation:
2x + y = - 2
<u>x + y = 5 </u> Subtract to get rid of the y
x = -2-5
x = -7

Step-by-step explanation:
We have been given that captain Umaima has probability 3/7 of hitting the pirate ship.
The pirate only has one good eye, so she hits the Captain's ship with probability 2/5.
The probability that pirate misses the captain's ship will be:

So the probability that pirate misses captain's ship will be 3/5.
Since both events are independent, so by the multiplication rule of probability we will get,
Therefore, the probability that the Captain hits the pirate ship, but the pirate misses will be
