Step-by-step explanation:
3^-9/ 3^-12
Simply change the division into multiplication. The denominator will become numerator. We are doing so because the base are same.
3^-9 * 3^12
Negative sign of power 12 become positive
Add the powers because the base is same.
3^-9+12
3^3
3^3 means multiply 3 three times
3*3*3
=27....
Answer:
$31.50
Step-by-step explanation:
30% of 45 is 13.5
45-13.5=31.5
we have
------> inequality A
The solution of the inequality A is the shaded area below the dotted line
see the attached figure N 
------> inequality B
The solution of the inequality A is the shaded area above the dotted line
see the attached figure N
The solution of the system of linear inequalities is the shaded area between the two dotted lines
see the attached figure N 
therefore
the answer in the attached figure N
