Step-by-step explanation:
3(-30x - 15y = -30) ...........(i)
15(6x + 3y = 6) ..............(ii)
Now,
-90x -45y = -90
90x +45y = 90
_____________
Every term is cancelled. so this system has no any solution so it means solution does not exist (DNE)
<span> He could draw a diagram of a rectangle with dimensions x – 1 and x – 6 and then show the area is equivalent to the sum of x2, –x, –6x, and 6.</span>
number of face cards in a deck of 52 cards = 12
total number of cards = 52
ways of choosing 'n' cards from 52 cards = ⁵²Cⁿ = 52!/(n!)(52-n)!
ways of choosing 'n' face cards = ¹²Cⁿ = 12!/(n!)(12-n)!
Probability = favorable outcomes/total outcomes
Probability of choosing n face cards = ¹²Cⁿ/⁵²Cⁿ
Probability of choosing n face cards = (12!/(n!)(12-n)!) / 52!/(n!)(52-n)!
= [ 12! * (52-n)! ]/[ (12-n)! * 52!)
Sorry, I can’t help you. You forgot to include a photo of the diagram.
