Answer:
1 hour and 20 minutes
Step-by-step explanation:
If 4 people take 3 hours, 1 person will take 4 times as long. This is 4*3=12 hours. If 9 people do it, it will take 1/9 of the time 1 person takes to do it, which is 12/9 = 1.3 recurring, or 1 and 1/3 of an hour.
No,it depends if like 1+0 then no and if 1+1=2 then yes
Answer:
i)D:
ii)R: 
iii) Y-int:(0,3)
Step-by-step explanation:
i) The given absolute value function is;
.
The absolute value function is defined for all real values of x.
The domain is all real numbers.
ii) The range is all y-values that will make x defined.
The given function,
.
has vertex at, (-3,0) and opens upwards.
This implies that, the minimum y-value is 0.
The range is 
iii) To find the y-intercept substitute x=0 in to the function.
.
.
.
The y-intercept is (0,3)
