Answer:

Step-by-step explanation:

1). The x-intercept (15,0) represents the time when container will be empty. In 15 minutes the container will have 0 gallons of water.

2). The y-intercept (0,120) represents initial amount of the water in container. The container had 120 gallons before a drain was opened.

3). The slope, m = 8, represents how fast container is loosing the water. Each minute there are 8 gallons of water less in container.

to fill a coffee mug at a local shop costs $2.50. the shop sells coffee beans foe $12 per pound. each pound makes enough coffee
myrzilka [38]

Answer:

There are a few possible answers so read explanation, but the one I will put up here is:

20.83

Step-by-step explanation:

First you have to find how much 100 cups of coffee costs in store.

To do this you will multiply 2.50 by 100 and get 250. So now we know 100 cups of coffee in store costs $250 whereas 100 cups at home is $12.

To find how many times greater the price in store is compared to the at home brew, you have to divide 250 by 12 and get 20.8333333....

We don't stop there though, because it asks us to approximate. I am not sure what it would like us to round to, but here are some possible approximations:

  1. 20.83
  2. 20.8
  3. 21

Any of those re reasonable approximations, you choose whichever you think the question wants, or whatever your teacher asks for.

Hope this helps

Use the graph of f(x) = log x to obtain the graph of g(x) = log x + 5.
galina1969 [7]

The graph of g(x) = f(x) + 5 will have the graph of f(x) moved 5 units upward. The best choice is the last one.

_____

Adding 5 to each y-value (the output of f(x)) moves it upward by 5 units.
