This would be (3/2)^2 = 9 /4 answer
Downwind DATA:
distance = 1330 ; time = 5 hrs ; rate = d/t = 1330/5 = 266 mph
---------------------------
Upwind DATA:
distance = 1330 ; time = 7 hrs ; rate = d/t = 1330/7 = 190 mph
---------------------------
Equations:
p + w = 266
P - w = 190
-------------
Subtract 2nd equ. from 1st to get:
2w = 76
w = 38 mph (speed of the wind)
Answer 38mph
Answer: 96.77
Step-by-step explanation:
Y=-2x+2
y=x2-2x+4
is the value of x such that when you plug it into both equations, they both produce the same value of y, or the value of x such that
-2x+2=x2-2x+4
solving this equation----------> x2=-2, taking square root of both sides gives x= ±√2i, or the system has no real solutions but has 2 complex solutions. If you graph both functions in the xy-plane, where x, y are real numbers, you' ll see they do not intersect, which implies there is no real number solutions.
