Graph?
well
for
|a|>b solve
a>b and a<-b
|4w+1>11
solve
4w+1>11 and 4w+1<-11
minus 1 both sides
4w>10 and 4w<-12
divide both sides by 4
w>5/2 and w<-3
graph the points -3 and 2.5
shade outside
not including
2.
union means include all common to both
so
2. 1,2,3,4,6,8,9
3. 1,2,3,4,5,7,10
4. interseciton so only ones common to both, so 4
5. null set (empty)
Answer: average speed is 8 km/h
Step-by-step explanation: in upstream his speed is 9 km/h -3km/h.
So his speed is 6km/h and he needs time t= s/v= 1.5 km: 6 km/h = 0.25 h
Downstream his speed is 9 km/ + 3km/h = 12km/h and time is
1.5 km:12km/h= 1/8 hours= 0.125 h
Average speed v = s/t = 3km: (0.25 + 0.125 ) h = 8 km/h
Answer:
at x = 
, 
= -3.5
Step-by-step explanation:
The given equation is
Now, substitute the value of x = in the above equation.
The given equation simplifies to,
now, 
So, the equation become
-3(2) + 2 + (1/2) = 
= -3.5
So, at x = , = -3.5
We need to follow PEMDAS
