Ответ:
=
6 hours
Step-by-step explanation:
An airplane can travel in one hour = 550 miles
Distance between London to Montreal approximately = 3300 miles
Let the Time taken by the airplane from London to Montreal be = x
The expression will be
=
x =
x = 6 hours
It will take 6 hours to fly from London to Montreal.
Ответ:
recall that to find the x-intercept we set y = 0 and solve for "x".
and to find the y-intercept, we set x = 0 and solve for "y", so let's do so
x = 0, so then the equation turns into
y = 3x² + 5x - 2
y = 3(0)² + 5(0) - 2
y = -2
when x = 0, y = -2, ( 0 , -2 ).
