This would be something like [5] or -[-5] which is absolute value (>.<)
-y + 6 + 6y = 9
First, simplify -y + 6 + 6y to 5y + 6. / Your problem should look like:
Second, subtract 6 from both sides. / Your problem should look like:
Third, subtract 9 - 6 to get 3. / Your problem should look like:
Fourth, divide both sides by 5. / Your problem should look like:

Answer as fraction: y =

Answer as decimal: 0.6
Answer:
D
Step-by-step explanation:
m + 9 can be +ve or -ve or 0.
m can be any number, even lesser than -9 to make it +ve. [-10+9 = -1 = -ve no.]
Or, maybe greater than -9 to make m+9 +ve. [-8 + 9 = 1 = +ve no.]
Or, maybe -9 only so that m+9 is 0
[ -9 + 9 = 0 ]
It can be -ve, +ve and 0 as well.
729-243=486
486×3=1458
1458+729=2187(x=7)
1458×3=4374
4374+2187=6561(x=8)
4374×3=13122(average rate of change for interval 8 to 9)
13122+6561=19683(x=9)
Ans: B
