Answer:
 b= 10 miles/hr and c= 5 miles/hr
Step-by-step explanation:
Let it's downstream and upstream speed be d and u respectively
also speed of the boat be b and speed of stream be c.
as per question d = 150/10= 15 miles/hr 
and, u= 150/30= 5 miles/hr
also we know d= b+c = 15.....i and u = b-c= 5....ii
solving i and ii we get b= 10 miles/hr and c= 5 miles/hr
 
        
             
        
        
        
Answer:

Step-by-step explanation:
4x - 1 < 11
Add 1 on both sides.
4x - 1 + 1 < 11 + 1
4x < 12
Divide both sides by 4.
(4x)/4 < 12/4
x < 3

Answer:
Angle QPM and Angle LMP are alternate interior I'm pretty sure, so I think B or  second choice.
 
        
                    
             
        
        
        
p(x)= x-2
g(x)= 2x^3 + 3x^2 - 11x - 6
first we have to find the zero of the polynomial of x-2
p(x)= x-2 = 0
          x=2
therefore,
p(x)= 2x^3 + 3x^2 - 11x - 6
p(2)= 2*2^3 + 3*2^2 - 11*2 - 6
       = 2*8 + 3*4 - 11*2 - 6
       = 16 + 12 - 22 - 6
       = 28-28
      = 0
Hope it helped u, ^_^.
