Answer:for the first one, you should probably do a table of values then answer the question, i usually find that helpful
Step-by-step explanation:
Answer:
c=-5
d=1
Step-by-step explanation:

I'm going to reorder the left-hand side. Multiplication is commutative.

Since the bases are the same in
and the operation is multiplication, I'm going to add the exponents giving me:

So this implies we have two equations to solve:
and 
So the first equation can be solved by dividing both sides by 4 giving you
.
The second equation can be solved by subtracting 2 on both sides giving you
.
Answer:
T=N*M and he needs to read 44 books.
Step-by-step explanation:
Note: Let T represent the total amount of books that Alan needs to read in 11 months.
If we plug in the information we have been given we will find the total:
T=N*M
T=4*11
T=44
Alan has to read 44 books within a 11 month period.

Your answer is, get the variable by itself.
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.
