look at each equation take equation I for example y = 2x then look at each table take the x value plug it in for the equation and see if you get the y value if you don't move on. so on this instance y = 2x I'm just going to plug in 2 * -2 gives me - 4, 2 * - 1 gives me -2, 2 * 0 gives me 0, 2 * 1 gives me 2 so the answer to table c is table c matches with equation i. keep doing that on your own and you should be able to get the rest

Emily has $3.15 worth of dimes and quarters. She has twice as many dimes as quarters. Determine the number of dimes and the numb
Cerrena [4.2K]

Answer:

The number of dimes is <u>14</u> and the number of quarters is <u>7</u>.

Step-by-step explanation:

Given:

Emily has $3.15 worth of dimes and quarters.

<em><u>She has twice as many dimes as quarters.</u></em>

Now, to determine the number of dimes and the number of quarters.

Let the number of quarters be x.

And the number of dimes be  2x.

So, the total worth of dimes and quarters = $3.15.

Now, to get the number of dimes and quarters:

According to question:

0.10(2x)+0.25x=3.15

0.20x+0.25x=3.15

0.45x=3.15

<em>Dividing both sides by 0.45 we get:</em>

x=7.

<em>Thus, the number of quarters</em> = 7.

<em>So, the number of dimes</em> = 2x=2\times 7=14.

Therefore, the number of dimes is 14 and the number of quarters is 7.

What is the recursive formula when given the explicit formula for the following geometric sequence?
satela [25.4K]

Answer:

C

Step-by-step explanation:

Take a careful look at a(n) =  6(-8)^(n-1).

The first term is 6.  This is the result if we let n = 1; 6(-8)^0 = 6(1) = 6.  Thus, we can immediately eliminate possible answer choices A and D.

What's the next term?  Knowing that the first term, a(1), is 6, the next term is found by multiplying this 6 by (-8)^1, obtaining -48.

The next (third) term is found by multiplying this -48 by (-8)^2, obtaining -48*(+64), or - 3072.

Note that the sign of (-8)^(n-1) alternates, being odd when n-1 is odd and even when n-1 is even.

Answer C is the correct one.
