Question

FAN AND MEDAL WILL BE AWARDED <3
Yet another simple question I just do not understand :(
(Ignore the marked answer once more)

Answer 1

Inverse right?

Answer 2

Yes I believe so

Answer 3

First what you have to do is switch the y and x

Answer 4

But there is no "y" :o

Answer 5

So f(x)=7x-13 becomes ------> x=7y-13
Now just solve fir y again

Answer 6

f(x) is another way of saying y

Answer 7

Ohh right ! I forgot !

Answer 8

Yup, and that's all you have to do :)

Answer 9

Thank you :) But I'm a little stumped on how to solve the equation .. Do I add 13 to both sides ?

Answer 10

Yup, and then divide :)

Answer 11

This is what it should look like now , right ? 13x = 7 ? Because that's not what any of the options look like D:

Answer 12

You can't combine the x and 13, they're not like terms

Answer 13

This is how you do it.
