Answer:

Step-by-step explanation:

f(x) = x + 2.....change f(x) to y

y = x + 2....now switch x and y and solve for y

x = y + 2

x - 2 = y....change y to f-1(x)...represents an inverse

f-1(x) = x - 2 <== ur inverse

Converting percent into decimals
blagie [28]
To convert a percent to a decimal, you move the the decimal left two places to convert the percent to a decimal. For example, if you were to convert 14% to a decimal, you move the decimal left two places so that 14% converted to a decimal would look something like this: 0.14

A jet ski rental company charges h dollars for the first hour its jet skis are rented and k
skad [1K]

Answer:

C. h + k (t - 1)

Step-by-step explanation:

<em>If we use an example, you can plug in the numbers and test out which equation works. Say the first hours costs $10 and each hour after that is an additional $5. If someone rents a jet ski for 4 hours, how much did it cost?</em>

The first hour = $10

The 3 additional hours (totaled) = $15

Cost = $25

<em />

<em>So now that we know the cost, we can plug in our numbers to these equations to find which one comes out with $25.</em>

h = 10

k = 5

t = 4

<u>A</u>. 10 + 4 + 5 = <u>19</u>

<u>B</u>. 10 + (4 · 5) = 10 + 20 = <u>30</u>

<u>C</u>. 10 + 5 (4 - 1) = 10 + 5 (3) = 10 + 15 = <u>25</u>

<u>D</u>. 10 + 5 (4 + 1) = 10 + 5 (5) = 10 + 25 = <u>35</u>

<u>E</u>. 10 + (4/5 - 1) = 10 + (-0.2) = <u>9.8</u>

<em>C is the only problem that comes out as $25, therefore it must be the correct answer.</em>

The average size of a certain computer datafile is 255 kilobytes. 10 million of these datafiles can be stored in a harddisk.
mr_godi [17]

Answer:

Hi! Your answer here is 2550 GB. To find this answer, we multiply 255 (the number of kb) by 10,000,000 (the number of files.) This gives us 2,550,000,000 KB. There are 1,000,000 kb in 1 GB, so we divide 2,550,000,000 by 1,000,000, which gives us 2550. 2550 GB of files can be stored.
