amid [387]

Answer:

It costs $15 a month to play the video game.

The initial cost is $45.

The y-variable represents the cost in dollars.

The x-variable represents the number of months.

Step-by-step explanation:

If you break the function down, you're going to have:

<u>Total = Monthly Cost + Initial Cost</u>

In this case, 15x is your monthly cost, as you can think of x as the number of months meaning:

  • 15 for the first month (x = 1)
  • 30 for the second month (x = 2)
  • 45 for the third month (x = 3), and so on

Our initial cost is always going to be a set amount, thus our constant, $45.

This leaves y as our total, which makes sense, as it's all alone on one side of the equation, where as all the costs are bunched together on the right side.

Hope this helps!

Kofi estimated that he would run a total of 10 km in 1 h. In 1 h, he actually ran 46 times around a track 0.25 km long, going a

The equation to find percent error is

\frac{actual-theoretical}{theoretical}*100

where actual is the value that actually came out (in this case, 11.5 km) and theoretical is the value that was supposed to come out (in this case, 10 km).  Just plug in the numbers and simplify.

\frac{actual-theoretical}{theoretical}*100\\\\\frac{11.5-10}{10}*100=\frac{1.5}{10}*100=15\%\ error

So, the true answer would be 15%.  Apparently, the question you're asking takes 11.5 as the theoretical and the 10 as the actual (which I personally disagree with)

If you plugged in the numbers that way, the answer comes out to 13.04%.  So, the correct answer for your answer choices is c. 13%
