If my. omcast bill was 29.99 after taxes how much would it be a month

ikadub [295]

You don't say what the tax rate is. Supposing it were 5%, then your bill would be 1.05($29.99) = $32.49.

Which of the following represents a geometric series (remember what a series is as opposed to a sequence)?

juin [17]

Answer:

4 + 12 + 36 + ...

Step-by-step explanation:

4, 12, 36, ... is a geometric sequence, it has a common ratio of $r=\frac{36}{12}=\frac{12}{4}=3$

When we add the terms of a geometric sequence we get a geometric series.

4+12+36+ ... is a geometric series, it has a common ratio of $r=\frac{36}{12}=\frac{12}{4}=3$

4 + 12 + 20 + ... is not a geometric series because it has no common ratio

$\frac{20}{12}\ne \frac{12}{4}$

The second choice is correct

Solve the system of equations. How many solutions foes the system have? Help pls :D

jenyasd209 [6]

Answer:

Infinitely Many Solutions

Step-by-step explanation:

Step-1: Re-write the equations into correct form.

=> 6x + 3y = 24

y = -2x + 8

=> 6x - 24 = -3y

-2x + 8 = y

Step-2: Multiply "-2x + 8 = y" by 3.

=> 6x - 24 = -3y

-6x + 24 = 3y

Step 3: Subtract or Add if needed

=> 0 = 0

Because we got a result 0 = 0, this means that the system has infinitely many solutions.

Hoped this helped.
