Each following number is 4 more than previous, so it is arithmetic sequence.
a(1)=8,
d=4
a(n)=a(1)+d(n-1)
a(n)=8+4(n-1)=8+4n-4=4+4n
a(n)=4n +4
Correct answer is A.

6x – 4y = -5<br>4x + 5y = -11​
kipiarov [429]

Answer:

x= -1.5, y= -1

Step-by-step explanation:

6x= -5+4y

x= (-5+4y) / 6

4((-5+4y) / 6) + 5y = -11

4(-5+4y) + 5*6y = -11*6

-20+16y+30y= -66

16y + 30y = -66+20 = -46

y(16 + 30) = -46

y= -46 / (16 + 30)

y= -46 / 46

y= -1

x= (-5+4(-1)) / 6

x= (-5-4) / 6

x= -9 /6

x= -1.5
