B. (-m)^n
C. (-1)m^(n + 1)
D. (-1)m^(n - 1)
Answer:
A. m(-1)^(n-1)
Step-by-step explanation:
The degree of m doesn't change so none of the expressions with n as an exponent of m can possibly be correct. That leaves only choice A.
_____
You will find that when alternating signs are required, the term (-1)^n will be a factor. An offset of ±1 can be added to the n to make the initial sign be what you want. Here we want +1 for n=1, so an exponent of (n-1) is appropriate.
The general term for the sequence m, -m, m, -m, ... is m(-1)^(n-1). This is correct because -1 when raised to an odd power gives -1, and when raised to an even power gives 1, ensuring alternation between m and -m.
The question refers to a sequence where the terms alternate between positive and negative values of m. The general term that describes such a sequence is m(-1)^(n-1).
This term works because when raised to an odd power, -1 gives -1, and when raised to an even power, -1 gives 1. Thus, the expression alternates between m and -m for different values of n.
For instance, when n is 1, the term is m; when n is 2, the term is -m; when n is 3, the term is m; and so on. Therefore, the correct answer is option A: m(-1)^(n-1).

Answer:
Step-by-step explanation:
Pick any 2 points and then plug it in to the formula for slope
y2-y1
_____. (Rise over run)
x2-x1
Pick 2 ordered pairs (x,y) and then plug in the respective values for x and y
Once plugged in, subtract for the top and bottom values
Then divide the values
The answer is the slope
Simplified expression-?
Value-?
The expression 3x + 7x - 28 + 31 - 8x simplifies to 2x + 3. When x equals 2043, the value of the Simplifying Expression is 4089.
The given expression is 3x + 7x - 28 + 31 - 8x.
To simplify the expression, we first group together the like terms.
Thus, the expression becomes (3x + 7x - 8x) + (31 - 28).
This simplifies further to 2x + 3.
Next, to find the value of the expression for x = 2043, we substitute 2043 for x into the simplified expression, resulting in 2*2043 + 3 = 4089.
Therefore, the simplified version of the expression is 2x + 3 and the value of the expression for x = 2043 is 4089.
