Answer:
i don't have the table so no one can answer
Step-by-step explanation:
An excluded value is one where the bottom of the fraction = 0.
In your case 1-3x=0
1=3x
x=1/3
At this point, the function does not exist. If you were to draw a graph of it, there wouldn't be a y-value corresponding to x=1/3.
Answer:
(x) =
Step-by-step explanation:
let y = f(x), then rearrange making x the subject
y = 
x + 4 ( subtract 4 from both sides )
y - 4 = x ( multiply both sides by 5 to clear the fraction )
5y - 20 = x
Change y back into terms of x with x = (x) , then
(x) = 5x - 20
The answer you are looking for is -11/10 or - 1 1/10.
To find this answer you must first make the denominators the same. To do this, multiply 2/5 by 2/2 to get 4/10. Finally, subtract the two fractions, keeping in mind the denominators stay the same. -7/10 - 4/10 = -11/10 or - 1 1/10.
I hope this helps!
