Find the inverse of y=7x-10. Is the inverse a function?

Answers

Answer 1

Answer:

Answer: $f^(-1)$ (x) = $(x+10)/(7)$

Step-by-step explanation:

To find the inverse , all we need do is to make x the subject of the formula.

y = 7x - 10

Add 10 to both sides

y + 10 = 7x

divide both sides by 7

Therefore:

x = y + 10 / 7 , that is

$f^(-1)$ (x) = $(x+10)/(7)$

Answer 2

Answer:

Answer:

Step-by-step explanation:

y=7x-10 calculate x : 7x-10 =y

7x = y+10

x = 1/7 y +10/7

the inverse of y=7x-10 is ; y = 1/7 x +10/7

How do I write 97.356 pounds in word form?

Answers

Ninety-seven and three hundred fifty-six hundreds.

I'm not too sure though

Final answer:

The number 97.356 pounds written in word form would be 'ninety-seven point three five six pounds'. When writing decimals in word form, use 'point' for the decimal, and state each digit individually after the decimal.

Explanation:

To write 97.356 pounds in word form, simply write it as 'ninety-seven point three five six pounds'

This is simply a conversion of each digit and the decimal point into its corresponding word in the English language. The 'point' corresponds to the decimal point in the number, and 'ninety-seven', 'three', 'five', and 'six' correspond to the digits in the number.

In general, when converting decimal numbers into word form, remember to say 'point' where the decimal occurs, and then state each digit after the decimal individually.
