Answer:

$15+x

x in dollars

Step-by-step explanation:

Subscription per month=$15

Cost of each downloaded song per month=$15 + 1

If x number of songs are downloaded in a month

The cost of downloading x songs= $15 + x

Where,

$15 = fixed cost ( subscription)

x= variable cost( each unit of songs downloaded)

If 20 songs are downloaded in a month.

The cost of downloading the 20 songs

=$15+$20

=$35

8х + 7y= -5<br> X= -3y - 7
GrogVix [38]

Answer:

x = 2

y = -3

Step-by-step explanation:

Step 1: Write systems of equation

8x + 7y = -5

x = -3y - 7

Step 2: Solve for <em>y</em>

  1. Substitute 2nd equation into 1st: 8(-3y - 7) + 7y = -5
  2. Distribute 8: -24y - 56 + 7y = -5
  3. Combine like terms: -17y - 56 = -5
  4. Add 56 to both sides: -17y = 51
  5. Divide both sides by -17: y = -3

Step 3: Solve for <em>x</em>

  1. Substitute <em>y</em> to find <em>x</em>: x = -3(-3) - 7
  2. Multiply: x = 9 - 7
  3. Subtract: x = 2

Step 4: Check

<em>Plug in x, y into an original equation to verify it's a solution.</em>

2 = -3(-3) - 7

2 = 9 - 7

2 = 2

Snezhnost [94]

\bf \textit{Amount for Exponential Decay using Half-Life} \\\\ A=P\left( \frac{1}{2} \right)^{\frac{t}{h}}\qquad  \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\to &900\\ t=\textit{elapsed time}\to &90\\ h=\textit{half-life}\to &15 \end{cases} \\\\\\ A=900\left( \frac{1}{2} \right)^{\frac{90}{15}}\implies A=900\left( \frac{1}{2} \right)^6\implies A=14.0625
