Answer:
either 81 or 162
Step-by-step explanation:
I got 81 by 27×12
162=27×12×2
Graph is incorrect.
Find points (x,y)
If x=#, what does y=?
Example:
Y=5x+4
Y=5•0+4
Y=0+4
Y=4
Points:
(0,4)
(-1,1)
(-2,-6)
Also, only draw the line in areas where x≤0
Meaning nothing should be on the right half of the square.
The range means what Y values are possible?
When draw properly, with nothing on the right half, the highest Y value will be 4.
So, the range is y≤4
given,
1st term(a)= -2
2nd term (t2) =-12
3rd term (t3) =-60
4th term(t4)= -120
here common ratio (r)=t2/t1=t4/t3
or, -12/-2= -120/-60
or,6=2
hence,no -12, -60, -120 aren't in a geometric sequence because their common ratio aren't same.

Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
We use PEMDAS to solve this,
so P stands for parentheses, so that's where we start.
We first, square the innermost parentheses with the exponent which is the E in PEMDAS, then then the outer parentheses
-12/3*(-8+16-6)+2
-12/3*(2)+2
Now we divide as in Division in PEMDAS.
-4*2+2
Now we multiply as in Multiplication in PEMDAS.
-8+2
Now we add as in A for Addition
-6
In PEMDAS, Multiplication doesn't always come before division, and same for addition and subtraction.
