Consecutive odd integers are separated by 2. The 3 consecutive odd integers are
n
n + 2
(n + 2) + 2 = n + 4
Given:
n + (n + 2) + (n + 4) = 51
3n + 6 = 51
n = (51 - 6)/3 = 15
n + 2 = 15 + 2 = 17
n + 4 = 15 + 4 = 19
so your final numbers are 15, 17, and 19
Yeah, these are tough.
When the plane is flying in the same direction as the wind,
the wind helps it cover ground faster.
Plane + Wind = 460 mph
When the plane is flying opposite to the wind, the wind makes it
cover ground slower.
Plane - Wind = 400 mph
================================
OK. So far we have
Plane + Wind = 460 mph
Plane - Wind = 400 mph
Add the two equations, and you get
2 Plane + zero = 860 mph
Divide each side by 2: Plane = 430 mph
Plug that into the first equation: 430mph + Wind = 460 mph
Subtract 430 mph from each side: Wind = 30 mph
Answer:
y+3=-11/7(x-2)
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(8-(-3))/(-5-2)
m=(8+3)/(-7)
m=11/-7
m=-11/7
y-(-3)=-11/7(x-2)
y+3=-11/7(x-2)
Answer:
y = 2x-2 if x <= 2
y = 3 if x > 2
Step-by-step explanation:
y = mx + b
and closed dot means = to
