Answer:
x = 1 ,or x = -7
Obviously, the true answer is not in the options given.
Step-by-step explanation:
x² + 6x - 6 = 10
The above equation can not be factorized, hence the use of Almighty Formula.
x = [-b +- √b² - 4ac] / 2a
Where a = 1, b = 6, c = -6
x = [-6 +- √6² - (4*1*-6)] / 2*1
x = [-6 +- √36 - (-24)] / 2
x = [-6 +- √36 + 24] / 2
x = [-6 +- √60] / 2
x = [-6 +- 7.75] / 2
x = [-6 + 7.75] / 2 ,or x = [-6 - 7.75] / 2
x = 1.75/2 ,or x = -13.75/2
x = 0.875 ,or x = -6.875
Approximately
x = 1 ,or x = -7
Answer: 7
2x=4
x=2
3x+1=3(2)+1=7
Since they give updates every 18 minutes, thus any time being a multiple of 18 after 2 pm will be the time they give update.
5:30 pm is 3 hours 30 minutes for 2 pm or 150 minutes from 2 pm.
In 150 minutes, there are eight 18 minutes that have passed and is remaining 6 minutes for the next multiple of 18.
Therefore, you have to wait for 6 minutes for the next weather update.
