The first thing we must do for this case is to define a variable.
We have then:
n: unknown number.
We write the algebraic expression:
13 - 4n
For n = 3 we have:
13 - 4 (3) = 13 - 12 = 1
Answer:
An expression that represents this phrase is:
13 - 4n
its value if n = 3 is:
1
The answer is 0.027, you are correct. 0.3 to the third power means 0.3 x 0.3 x 0.3 and that equals 0.027
Answer:
Step-by-step explanation:
Notice that the series: 1 - 3 + 9 - 27 +... clearly has powers of the factor 3 in its terms and it is also an alternate series (the terms alternate from positive to negative). The terms are positive for 
(even terms) , while the odd terms 
are negative. (so most likely there should be a factor (-1) in the common ratio.
We can then represent it with the following summation expression:
given that each of its first four terms are:
Answer: in a quiet room or the library,
also you better summarize your geometry lessons and remember the formulas :P
Answer:
This is a linear function.
Step-by-step explanation:
A linear function is a straight line. Once you graph the equation, you get a staright line, therefore, it's linear.
