Answer 6

???? im so confusewd~!!!!!1

Answer 7

ok lets go slow

Answer 8

\[y=\frac{5}{x-4}\] and you want to know what value you CANNOT substitute for \(x\)

Answer 9

ok

Answer 10

the only thing you have to worry about is that you are not allowed to divide by 0

Answer 11

in other words \(\frac{5}{0}\) is undefined, it is not a number

Answer 12

so you have to only be concerned with what value of \(x\) would make \(x-4\) be zero

Answer 13

solve this problem by writing
\[x-4=0\] and solve for \(x\) in one step
if \(x-4=0\) then \(x=4\) so you may NOT have \(x=4\) and that is the excluded value

Answer 14

ooo ok thanks
