Answers

Answer 1

Answer:

Answer:

f^-1(x) = (x - 1)/2

Step-by-step explanation:

f(x) = 2x + 1

y = 2x + 1

x = 2y + 1

2y + 1 = x

2y = x - 1

y = (x - 1)/2

f^-1(x) = (x - 1)/2

Answer:

815

Step-by-step explanation:

First you put the value of x from the table into the formula provided.

y = -670 + 33(x) <= plug in the x value from the table

y = -670 + 33(45) <= multiply 33 * 45

y = -670 + 1485 <= add the two terms (which you will subtract because one is positive and one is negative.

y = 815

How would you round off a number to one decimal place? For example would 67.39 become 67.4

Answers

you take the second decimal, and if it is 5 or over, you increase the first decimal by one. If the number is 17.96,you increase the first decimal by one which gives you 18. If the question asks for 1 decimal place, than put 18.0 :)

when rounding off numbers to specific decimal places look at the number after that place. If that number is less than 5 then keep the needed decimal the same. if it is greater than 5 then round up by one.

Examples:

15.69 ⇒ 15.7
15.64 ⇒ 15.6

17.890 ⇒ 17.89
17.898 ⇒ 17.90
