Answer:
16 MPH boat speed still water
5 MPH current speed
Step-by-step explanation:
84/4 - x = 55/5 + x
x = (84/4-55/5)/2 = 5 mph current speed in MPH
11+5 = 16 is boat speed in MPH
21 MPH downstream, 11 MPH upstream
Answer:
C. 0, -1, 3
Step-by-step explanation:
Note: There is no graph. I assume you mean "zeroes/roots" by "solutions".
x(x^2-2x-3)=0
/(x^2-2x-3)
x=0
x^2-2x-3 = x^2+x-3x-3 = x(x+1) + ( -3(x+1) = (x-3)(x+1)
/(x-3) --> x +1 =0, x=-1
/(x+1) --> x-3 = 0, x=3
What you have to do is divide. Divide 720 - 60 = 12. So there are 12
