It is the first answer. Notice that if you multiply it out you get 6x + 30, and they have factored out the 6.
Which of the following sets of ordered pairs satisfies a linear function? a. (-1,5), 2,10), (3,15), (4,18), (5,22) b. (2,4), (4,
finlep [7]
The best answer is B (2,4), (4,6), (6,8), (8,10).
I hope this helps.
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)
The third one [15x+30y-220]
