Answer:
See below. 
Step-by-step explanation:
Recall that the x-intercept is basically: (x,0). 
In other words, we just need to substitute y with 0 in order to find the x-intercept. 
Thus, we will have:

Answer:
19 28/33
Step-by-step explanation:
lets work out the whole number parts first:
= 19 + 17 - 16 = 20.
4/12 + 2/11 - 6/9
= 1/3 + 2/11 - 6/9
Find the LCM of the denominators:
3 = 3
11 = 11
9 = 3*3
- so the LCM is 3*3*11 = 99.
So we have:
33/99 + 18/99 - 66/99
= 51/99 - 66/99
= -15/99
= -5/33
So the answer is  20 - 5/33
= 19 28/33
You just had to subtract 5/33 from 20.
