The cell phone plan from Company C costs $15 per month, plus $12 per gigabyte for data used. The plan from Company D costs $75 per month, with unlimited data. Rule C gives the monthly cost, in dollars, of using gigabytes of data on Company C’s plan. Rule gives the monthly cost, in dollars, of using gigabytes of data on Company D’s plan.

Sara wants to know what company to go with if her average gigabyte usage is 7 gigabytes per month. Explain which plan she should use, Company C or D? Make sure you support your choice with mathematical evidence.

Answers

Answer: Company D
Step by step explanation:
First we need to figure out how much money it would be for company C. If it is $15 per month and $12 per gigabytes used. We would set up and equation that would look like 15 + 12g (g= gigabyte used) and in this case we would substitute G for 7 which would look like 15 +12(7), 15 + 84= $99. Meaning that if Sara were to go with Company c she would be spending $99. Not we would solve for Company D, there is not much to solve for Company D considering that it is only $75 a month and includes unlimited data. If Sara were to go with Company C she would be spending $24 more than sue if she were to choose company D.
Hope this helps!

How many more kilometers did Shannon run on Friday than on Saturday?
kilometer

PLEASE HELP

Answers

Answer:

Shannon run 1.5 km more on Friday than on Saturday.

Step-by-step explanation:

From the given table

Distance run on Friday = 4/2 = 2 kmDistance run on Saturday = 1/2 = 0.5 km

In order to run how many more kilometers Shannon run on Friday than on Saturday, we need to subtract the distance run on Saturday from the distance run on Friday.

i.e.

Friday run - Saturday run =  2 - 0.5

                                          = 1.5 km

Thus, Shannon run 1.5 km more on Friday than on Saturday.

i think the answer is C :)

Answer:

C: y = |x-2| + 3

Step-by-step explanation:

When dealing with transformations, the numbers in the parentheses is the horizontal translation and the numbers outside the parentheses are vertical translation. The only reason the lines are | rather than ( is that they are absolute value.

When taking the horizontal measures, you always flip the sign. So since it is going to the right 2 times, you would think it would be +2, but since it is in the parentheses it would be -2.

When taking the vertical measures, it's just standard thought. So since it is up 3 it would be +3.

Putting all of that together would give you |x-2|+3

Step-by-step explanation:

5, 11, 18, 26,

The difference between 5 and 11 is 6.

The difference between 11 and 18 is 7.

The difference between 18 and 26 is 8.

As you can see their difference increases by 1, so the next difference would be 8 + 1 = 9.

26 + 9 = 35

And the next difference would be 9 + 1 = 10.
