5.
aritmetic is same increase per term
14 to 21 is 7
21 to 42 is 21
7≠21
no
6.
decreases by 4 each time
an=a1+d(n-1)
an=10-4(n-1)
n=12 for 12th term
a12=10-4(12-1)
a12=10-4(11)
a12=10-44
a12=-34
it is -34
7.
missing term is y
22+n=y
y+n=34
22+n+n=34
22+2n=34
minus 22 from both sides
2n=12
divide both sides by 2
n=6
22+n=y
22+6=y
28=y
28 is answer
5. no
6. -34
7. 28
Answer:(-4,3)
Step-by-step explanation:
Here, Every equation has same slope (-4) and same y-intercept (3), so we don't need to calculate those.
Now, as coordinates are in left-portion, and also touches the line, it would be: y ≥ -4x + 3
