Question

The inverse of the function y = 7x + 5 is y=x+5/7 ???

Answer 1

is it true or false

Answer 2

x = 7y + 5
7y = x - 5
y = (x-5)/7

Swap the variables and work out the equation so that y becomes the subject.

Answer 3

so true??? right

Answer 4

nope.

Answer 5

@johana My solution was y = (x-5)/7, not y = (x+5)/7. You had the signs wrong.

Answer 6

@tyteen4a03 says, swap the variables x>y as he did and rearrange to solve for y.

Answer 7

so to inverse .. this sing have to change ??? so the answer is false
ok thank u :))

Answer 8

No, to inverse you need to swap the variables and change the equation so it becomes the form y = something again.
