D because for a sequence you can't have a -1st term so b is out and a and c mean the same thing so neither of them can be the answer

Answer: All integers where n ≥ 1

Step-by-step explanation:

We know that the domain of any sequence is the set of natural numbers \mathbb{N}.

Therefore, the domain for the given arithmetic sequence a_n=-5+3(n-1) is the set of natural numbers.

Since we know that the set of natural numbers starts with digit 1.

Therefore, the domain of the given arithmetic sequence is all integers where n≥1.

To join a local square dancing group, Jan has to pay a $100 sign-up fee plus $25 per month. Write an equation for the cost (y) b
klasskru [66]

Answer:

y = $100 + $25x

Step-by-step explanation:

y is the total cost

x is the number of months

The sign up fee is $100.

Each month would cost an additional $25 per month.

The total cost then would be the sign up fee plus the $25 for each month. Since we do not know the number of months, we will assign x.

So the equation would be:

y = $100 + $25x

Solving quadratic equations by factoring <br> m(m-3)=0
KatRina [158]
Because it has already been factored, we can solve it straight away. Now, since m is a variable, we yield the same result if m = 0 or m = 3 because we have two components to this equation.

We can either have m = 0 or m - 3 = 0
Hence, m is either 0 or 3

Algebra Complete the table.Write the
AURORKA [14]

Step-by-step explanation:

<em>In the second column, we can see that every value of n is being added by 6. </em>

  • Thus, the expression is n + 6.

<em>Now, let's substitute the value of n in each column to verify each column. Then, using the expression, let's find the value of n + 6 where n = 28.</em>

<u>When n is 12:</u>

  • n + 6 = 18
  • 12 + 6 = 18
  • 18 = 18

<u>When n is 15:</u>

  • n + 6 = 21
  • 15 + 6 = 21
  • 21 = 21

<u>When n is 21:</u>

  • n + 6 = 27
  • 21 + 6 = 27
  • 27 = 27

<em>Thus, the expression is proven correct. Now, let's find n + 6 when n is 28.</em>

<u>Finding n + 6 when n is 28:</u>

  • n + 6 = x
  • 28 + 6 = x
  • 34 = x

Thus, the missing value in the table is 34.

Solve the equations <br> 3x + 5y = 21 <br> -20x + 5y <br> show your work
Digiron [165]

Answer:

x=21/23

Step-by-step explanation:

Solve for x:

3x+5y=21−20x+5y

Add 20x to both sides:

3x+5y+20x=−20x+5y+21+20x

23x+5y=5y+21

Subtract 5y to both sides:

23x+5y+−5y=5y+21+−5y

23x=21

Divide both sides by 23:

x=21/23
